* About this file
=================

This file lists the most important user-visible changes for each official
release of VICE.  For the gory details, please use the subversion history:

$ svn log http://svn.code.sf.net/p/vice-emu/code > ChangeLog


* Upgrading
===========

If you run into trouble please try removing any VICE configuration files
left over from previous installs.
(vice.ini / .vicerc / vice2.cfg / vice-sdl.ini depending on platform)

Before reporting bugs, always try with a clean config: Run the emulator
with the "-default" command line argument or use "restore default config"
in the UI).


* Changes in Vice 3.7
=====================


** general
----------

- From now on VICE will write its version into the config file and show a
  warning message when using a config file from a different version.

- The binary monitor interface is stable now. Examples of projects using it:

  - https://github.com/GeorgRottensteiner/C64Studio
  - https://github.com/MihaMarkic/vice-bridge-net
  - https://github.com/Sakrac/IceBroLite
  - https://github.com/empathicqubit/vscode-cc65-debugger
  - https://github.com/rolandshacks/vs64

- Added Debian packages of development builds of the SDL2 and Gtk3 UIs and the
  headless build (amd64 only).

  You can find bleeding edge development builds on github:

  https://github.com/VICE-Team/svn-mirror/releases

  Whenever you stumble about a bug, please try with the latest development build
  first - perhaps we already fixed it :)

- Removed all kernal patching and load different ROM files instead. This is
  easier to handle and more logical anyway :)

- Renamed all included ROM files to use a more elaborate naming scheme, for
  example as in "kernal-901227-01.bin".

  Unfortunately not all included files could be identified yet - if you have
  related ROM dumps around yourself, please take your time to compare against
  the following, and let us know if you can identify one of these files:

  - C128 ROMs: kernalfi, kernalfr, kernalit, kernalno
  - Printer ROMs: mps801.bin, mps803.bin, nl10.bin
  - PET ROMs: chargen.de

  (Wanted in all cases is what the markings on the actual chip read)

- CRT emulation improvements:
  - uses measured (different) color coordinates for odd/even lines when possible
  - added option for U-only delay line (1084 style)

- More realistic handling of the case when two paddles are selected at the same
  time.

- Keyboard handling was rewritten / fixed
  - The case when two host keys are mapped to different CBM keys with different
    modifiers is handled differently (correctly) now, so some old keymap(s) may
    expose detail errors as a result - please report them!
  - Fixed Shiftlock/Capslock mapping
  - All extra keys that are not in the regular matrix are handled in generic
    code now.
    - used by C128 40/80 and CAPS keys, Restore
    - extra keys can operate in "non locking" mode

- More realistic behaviour of the virtual drive
  - always return 'files scratched' (instead of 'file not found'), even if the
    file does not exist

- More realistic behaviour when mounting images:
  - When attaching a d64 image to a 1571 drive, create an 'unformatted' image for
    the second side.
  - Create empty tracks for non existing tracks also when mounting gcr images

- SID fixes:
  - use a few more bits for better accuracy when calculating the 8580 filter
    DAC values.
  - fix filter ringing/self oscillating with 6581 and 8580

- CIA fixes:
  - Improved the CIA shift register.
  - Fix the case when pb changes value after changing the control bits for
    pb/pb7 output. Fixes the turn disk space detection of the 'Love' demo.

- Add SPT (Stupid Pet Tricks) userport joystick adapter emulation.

- Fixed use of SO_REUSEPORT on server sockets - this allowed multiple VICE
  instances to bind to the same port, with an indeterminant one receiving each
  incoming connection. Now uses SO_REUSEADDR instead, which allows use of a
  port that remains in the TIME_WAIT state after a previous process closed,
  but does not allow use of a port that is still in active use.

- Add DragonFly BSD support.

- Remove Android support.

  speakers on real hardware behave quite different in how much they "muffle"
  the sound.

- Fixed and document PET layout and US/DE keymaps.

* Changes in Vice 3.6.1
=======================

This is a service release which fixes some regressions and annoyances reported
by our users after the 3.6 release.


** general
----------

- Fixed sound buffer underrun behaviour, it will now cause a small glitch and
  no longer disable sound or flood the log with warnings.

- Do not write the log to a file instead of stdout when stdout is already 
  redirected to a file or pipe, so we can do just that on the shell.

- At exit, put quotes around parameters of the regenerated command line options
  so eg filenames with spaces in them will not break it.

- Suppress warnings about duplicated labels when playing back monitor commands
  to make mrsid a happy bunny.

- For cartridges that contain RAM that can be loaded from (and saved to) a file,
  do not init RAM on powerup if backed up by a file (mimic battery backup).

- Do not clear the keyboard input when a 'reset' hotkey was pressed. this allows
  to "hold" keys when pressing reset, for example "run/stop" when resetting FC3.
  Note that this still is limited by various other things, like the keyboard
  mapping and keys reserved by your window manager.

- FFMPEG recordings now default to mp4/h264/AAC instead of some divx avi bullshit.

- On smart attach automatically change the drive type also when not autostarting.
- In some cases the wrong drive was selected automatically on smart attach.

- Fixed sampler file loading.

** build system
---------------

- Version x.y.0 builds will now generate a version number of x.y (no .0).
  Additionally, support for semver style build labels has been added, allowing
  versions such as 3.6-beta, 3.6.1-beta, etc.

- Make configure check for *both* avresample and swresample, prefer swresample.

- MacOS bindist support for bundling avresample.

** C64 fixes
------------

- Added belgian/dutch keymap provided by sorex.

- Added support for the 21sec backup parallel cable.

- Set default ram size for ramlink to 16mb, enable it on ROM attach.
- Fix ramlink API calls for slot0, add missing ROM image setting to UIs.

** C128 fixes
-------------

- Various MMU mapping fixes.

** GTK3 fixes
-------------

- Tracked down and helped fixing an upstream GTK bug that made VICE crash on any
  keypress under certain conditions, making VICE work again for Jazzcat :)

- Fixed default joystick/gamecontroller mappings on Windows/Linux/MacOS.
- Fixed mapping logic to handle multiple events and duplicate mappings correctly.

- Allow negative coordinates for windows, this should fix restoring the window
  position that was broken on some multi-monitor setups.

- Monitor: remember and restore VTE window size and position.
 - Make the monitor window "remember" its position and size between invocations.
 - Allow setting the position and size via command line, using `-monitorxpos`,
   `-monitorypos`, `-monitorwidth` and `-monitorheight`.
 - Position and size is saved along with the settings.

- Made joystick/control port tabs only show the extra ports when they are
  available.

- Mouse pointer changes shape when hovering over clickable status bar items.

- CPU speed / FPS settings added to the main menu.

- Correctly use the LED colors for drives > 8.

- Fixed drive/tap popup menu labels, only display "#8:0" etc if the drive is a
  dual drive device in the context menus and directory popup menus. Only show
  "Directory of tape #1/#2" in xpet, show "Directory of tape" in other emulators.

- Added statusbar led for shiftlock.
- Added clickable 40/80colums LED to x128.
- Added clickable LED for the CAPS aka DIN/ASCII key in x128.

- Properly update both keyboard debugging widgets on x128.

- Don't grey-out sound setting widgets when sound is disabled, so configuration
  can be changed before enabling sound again.

- Various fixes related to the new hotkeys feature:
  - Allow for a few more modifiers when setting hotkeys.
  - Filter certain modifiers that are only getting in the way (eg numlock).
  - Remove old hotkey from the table when redefining.
  - Make Return/Enter trigger Accept in the dialog, make Escape trigger Cancel.
  - Only show actions that have a corresponding menu item.
  - Use hardware keycodes to figure out the key that was pressed. fixes eg the
    situation on macOS that hotkeys could not be defined because they produce
    various symbols.

** SDL fixes
------------

- Fixed mapping logic to handle multiple events and duplicate mappings correctly.

** macOS fixes
--------------

- Fixed macOS bindist not working if placed in path with a space in it. Also
  the runtime cwd will now default to the user’s home directory, unless launched
  using the CLI scripts in the root bin folder in which case the current cwd
  will be preserved.

- Gtk3: added MacOS specific .vhk (hotkey) files.

- FFMPEG recordings now work on Apple Silicon binary distributions

- The launcher .app apps no longer require Rosetta on Apple Silicon

* Changes in Vice 3.5
=====================

This release completes the transition to the new GTK3 based GUI and fixes a
bunch of long standing issues (see below).

We are looking for someone who can provide stable automatic nightly builds - for
this will work best on a Windows machine, or perhaps a Fedora server. We tried
our best to come up with a solution for Debian, but that didn't work out as
intended. If you think you can help in this area - please get in touch.

We welcome to the team:

empathicqubit - who wrote the new remote monitor binary interface

Roberto Muscedere aka OldWoman37 - who contributed the new Lt.Kernal, CMD-HD and
RAMlink emulations (C64 only)

** general
----------

- Remove explicit support for OS/2, AmigaOS. These platforms should be able to
  use the SDL port.

- VICE used to store its ROMs, keymaps etc into $PREFIX/lib[64]/vice, which
  isn't correct. Now VICE installs its data into $PREFIX/share/vice, which
  makes a lot more sense. The documentation location has changed as well, now
  the documentation is installed in $PREFIX/share/doc/vice.
  On Windows, the binaries and DLLs have been moved into /bin, according to the
  requirements of GTK/GDK.

- Emulator timing is now directly driven by the host system audio device.
  If sound emulation is disabled, timing is synchronized with the host clock.
  As part of this change, the choice of sound synchronization method has been
  removed.

- Emulation now occurs in blocks of time directly related to the sound fragment
  size. Previously, emulation of an entire frame happened as quickly as possible
  and then the host system would sleep until it is time to emulate the next
  entire frame. This means that user input is now visible to the emulated
  software with lower latency than before.

- Audio latency is much lower on all platforms, and new lower latency defaults
  have been set. Users are encouraged to try using smaller fragment sizes and
  experiment with finding the lowest stable buffer size on their system.

- Support for changing the emulator timing to target generating a specific number
  of video frames per second. Useful for smooth PAL scrolling on a 50Hz CRT, and
  also fun for playing games at 60fps to match a typical LCD screen refresh.

- The default behaviour on CPU JAM was changed to "continue" to better match
  the behaviour of the real machines. Additionally a "CPU JAM" message will
  be displayed in the status bar.

- A "quit emulator" option was added to the CPU JAM dialog

- The CPU JAM dialog now shows the number of the device whose CPU has crashed.

- Proper support for dual drives has been added

- Relative file support on the filesystem device

- Autostarting works from any drive (select the drive in the attach disk dialog)

- Added support for 2nd and 3rd joystick button (potx/poty), currently only via
  keyboard and via unix joystick driver.

- Added mapping for the THEC64 joystick

- New LT.Kernal emulation

- New CMD-HD emulation

- New CMD RAM-Link emulation

- New D9090/60 emulation

- New icons for the applications.

- We now use proper binary prefixes for memory sizes.
  Welcome in the 21st century!

- Recalculate the palette parameters when the videochip type changes, now we can
  actually see the subtle color differences :)

- Emulate a switch present on some compatible datasettes (not the Commodore
  ones). Turning the switch on makes the sound recorded on the tape audible.

- Fixed/improved "native" screenshots. It will now work with all videochips and
  always generate "best effort" results.

- The emulators will look for the config file at an alternative location first,
  before looking at the system wide location.
  - for windows that is the location of the .exe files
  - for Linux that is ~/.vicerc

- Fixed lightgun/pen emulation
  - use poty instead of potx for trigger for magnum lightphaser and inkwell
    lightpen
  - tweak lightphaser offset against a bunch of games

- Handling of settings and resources was improved a bit:
  - always reset resources to default before loading a settings file
  - new "-addconfig" option (or "load additional settings") loads additional
    resources from a file without resetting to defaults before. this can be used
    to keep custom setups separate from the regular settings.

- Fixed sysfile search path order.
  The order now is $HOME/.local -> path-of-binary -> VICE_DATADIR

- Fixed a bug in .tap file handling that caused some .tap files to not work in
  the preview widget(s)

- A bunch of files have been removed from the source tree because they didn't
  really belong there and/or contained outdated info:
  - hardware-sids.txt, the old info is now at
    https://vice-emu.pokefinder.org/index.php/Hardware_SID_Status
  - SDL-support.txt, the old info is now at
    https://vice-emu.pokefinder.org/index.php/SDL_Status
  - ffmpeg-support.txt, the old info is now at
    https://vice-emu.pokefinder.org/index.php/FFMPEG_Status

- Another bunch of files were removed because their content was hopelessly
  outdated and/or could be moved to other files:
  - removed ancient CHANGELOG files. Read NEWS for the recent changes. Refer to
    the SVN log for the gory details.
  - moved contents from FEEDBACK to README
  - removed INSTALL, AUTHORS, FEEDBACK
  - removed the MAN pages. Read the html or pdf manual instead.


** build system
---------------

Many changes and simplifications were made in the build system, to make
it more reproducible and match the expected standard behaviour:

- Add --disable-optimization (default=no) to make the buildsystem use -O0 for
  debugging.

- 'make dist' no longer needs '--enable-static-ffmpeg' to generate a working
  tarball.

- Fixed support for the —disable-silent-rules/—enable-silent-rules configure
  arguments.

- Added --enable-sandbox-mode switch. This switch will tell GTK3 to use
  'native dialogs' so we can properly support Flatpak and similar containers.

- Added -—enable-cmake to automatically generate cmake CMakelists.txt files for
  in-tree configured builds. Generating Xcode projects works, and this may
  allow generation of MSVC project files in the future.

- Add --enable-desktop-files for creating and installing .desktop files on Unix.

- Added --enable/disable-html-docs
- Added --with/without-mpg123 (default=no), makes MP3-decoding support optional
- Added --with/without-ogg-vorbis
- Added --with/without-flac (default=no)
- Update --with[out]-lame, make no default
- Make jpeg and gif support default to no
- Make using libpng the default, fail unless explicitly disabled
- Make ALSA and Pulse default to enabled, make OSS default to disabled
- Make MIDI support disabled by default
- Make new 8580 filter default
- Removed --disable-hwscale, always check for OpenGL with GTK3, error out when
  --disable-hwscale is used with SDL2

Properly report missing tools to generate docs:

- Fail on missing pdftex when PDF docs requested
- Checks for makeinfo and texi2dvi (from the texinfo package) and warns in the
  configure output at the end if they are missing, but will still build VICE.

Check presence of other tools instead of silently not using them:

- Made dos2unix mandatory to avoid surprises
- Fail if building for Windows and `icotool` is missing. It can be obtained by
  installing the `icoutils` package.

Some features have been deprecated and are now disabled by default:

- Added --enable-x64-image option to enable X64 image support, which is now
  disabled by default.
- Added --with/without-fastsid switch to enable/disable the fastSID engine
  (default is off).

** Monitor
----------

- Completely new binary remote protocol for debuggers. The older hack was
  removed - see the documentation for details.

- -moncommands finally work as originally intended and supports all monitor
  commands now. That means there are subtle differences in how certain things
  work. one important thing is that by default it will use an initial break
  point just after "reset".

- "-initbreak ready" can be used to place an initial wait for "ready", like
  autostart does, or "-initbreak reset" to break just after reset.
  For more details, read the documentation.

- ‘stop’ is no more ending up in recorded monitor command playback files
- Support `cd ~` to change cwd to $HOME
- Added 'mkdir' command
- Added 'rmdir' command
- Added "verify" and "bverify" commands to compare memory with a file
- Added optional address to the `screen` command
- `chis` shows the cycle count as well now
- Added option to configure the number of lines used for chis
- Added option to change the size of the scrollback buffer

- Added "dummy" command to enable or disable whether break- and watchpoints
  trigger at dummy accesses or not.

- Check watchpoints in the order they were added, that makes the output in the
  monitor less confusing when more than one watchpoint triggers at a time

- Show rasterline and cycle in both decimal and hex
- Add 'q' as a shorthand for 'quit'

- Improvements to the char/sprite display - use # over * for more contrast,
  show the memory value(s) alongside binary view and fix bug showing multiple
  sprites

- "list", "load" and "save" do now work with the filesystem device
- Drive numbers are now expected to be decimal
- Add monitor dump function to m6821 core
- Added info on head position/status to VIA io dump

- The display now (optionally) refreshes after each monitor command. this is not
  cycle exact right now (only per scanline).

- Fixed accessing cartridge memory
- Improve expansion port mode status output
- Fix io command to shows IO space in address order


** vdrive
---------

- The filesystem device now uses shortened filenames by default to increase
  compatibility.
- Disallow to silently overwrite existing files (optional, default is "no")
- Implemented "save @" to overwrite files (but do not simulate the well known
  related bugs)
- Basic support for REL files in the File System Device. (Using P00 format, or
  rather R00, is recommended)
- Fix some BAM track allocation issues in 8050/8250 disk images
- Avoid DISK FULL with 27 blocks free on .D80 / .D82.
- For D80/D82 images, when reading the directory, use the correct block to fetch
  the disk's name from. This corrects a bad disk name in directory listings when
  using a vdrive.
- Added proper creation of d1m, d2m and d4m images, the resulting image has 1
  native partition spanning the entire disk.
- When formatting or validating an 8050 or 8250 image, the header sector wasn't
  flagged as allocated. This resulted in VICE hanging when creating more than 80
  files on the disk.

** True drive emulation
-----------------------

- More realistic modelling of the floppy drive wobble
- Changed lower limit for drive RPM to 260 and upper limit to 340 (ie +/- 40).
  This is slightly more than possible with a real 1541.


** CPU fixes
------------

- Prevent IRQ/NMI from being served by the CPU when it has JAMed
- Perform all "dummy" accesses also in the non "sc" core
- Changed magic constant for LAX#imm to 0xEE as required(!) by wizball

** VDC fixes
------------

- Emulate VDC's internal buffer, issues with RFOVDC plasma part are fixed
- Several fixes for interlace, now vdcmodemania interlace parts all work and
  soci VDC test #5 works
- Improved VDC-FLI handling, 3 byte attribute offset doesn't always apply,
  fixes vdc-mcm demo and vdcmodemania fli part
- Fix issue with wrap around of VDC ram affecting vdcmodemania fli part
- Fixed VDC reg #28 bit #4, it sets the addressing mode, it does not actually
  reflect the amount of ram installed.
- Correct aspect ratio for PAL or NTSC
- Screen is resized automatically on PAL/NTSC change
- Corrected size of saved screenshots or videos
- Correct handling of unused bits in some registers
- Corrections and enhancements to monitor "io d600" dump

** SID fixes
------------

- Fixed the filter saturation
- Noise writeback fixes
- Envelope regression fix
- Fix the coefficients for the resid external filter
- Rough implementation of the shift register and waveform zero bitfade
- Added 4 possible additional SID chips for a total of 8 (x64*/xscpu64/x128 only)

** C64 fixes
------------

- Enable/disable datasette/tapecart as needed on autostart

- Several new cartridge types added:
  - The 'ZIPP-CODE 48' cartridge
  - The polish 'blackbox v8' cartridge
  - The polish 'Blackbox V3' cartridge
  - The polish 'Blackbox V4' cartridge
  - The polish 'Blackbox V9' cartridge
  - The 'REX RAM-Floppy' cartridge
  - The czech 'BIS-Plus' cartridges (2,4,8kb variants)
  - The polish 'SD-BOX' cartridge
  - The 'MultiMAX' cartridge
  - The argentinian HERO bootleg cartridge
  - The "GMod3" cartridge

- Action Replay fixes:
  - When reading from IO1 area when AR5 is enabled, the value currently on the
    bus will get written to the register, causing the famous bug/crash
  - Handle the broken mode 0x22 and emit a warning on potentially problematic
    reads

- Retroreplay fixes:
  - Allow reading back the status of the freeze button
  - Fix reads from IO1 when the clockport is not active.
  - Handle the somewhat broken mode 0x22 like on real retro replay

- Nordic Power fixes:
  - Fix writing to cartridge ram in mode 0x22

** C128 fixes
-------------

- FD2000/4000 work again, including burst mode
- Several bugs fixed in the MMU IO dump in the monitor.

** VIC20 fixes
--------------

- Added handling for 32k cartridge files that contain blocks 1,2,3 and 5.
- Fixed megacart nvram addressing
- External audio filter fix


** PET fixes
------------

- Teach VICE where BASIC 1 keeps the current screen line address, so that
  Autostart works.
- Made the UK business keyboard the default and moved it to the top of the list
  of keyboards. This makes the default setup work with the keymaps and editor
  ROM we have in VICE.
- For CRTC-less PETs, use screen setup values that work out to 60 Hz refresh.
- Tuned the display timing values for non-CRTC PETs
- Renamed PET ROMs to include their part number (in line with Zimmers). This
  should make it more clear which editor ROMs exist.
- The 4032B model used a wrong Editor ROM

** SDL fixes
------------

- Implemented mouse pointer auto-hiding
- Remember last position in the main menu

- Several Keyboard mapping fixes:
  - Fix (some) plus4 keymaps
  - Some pet keymap fixes
  - Updated/fixed symbolic mapping for italian keyboard
  - Some tweaks to symbolic keymap for german layout (plus4)
  - Added keymap from/for BMC64 (c64)

** GTK3 fixes
-------------

- Almost all causes of stuttering / audio glitches when interacting with the UI
  have been resolved.
- Cairo is completely gone, all major platforms use their native rendering
  backend
- Added hotkey "pause" to generate a screenshot from current canvas using a
  generated filename in the current working directory
- Rearranged cartridge/io settings around a bit. not perfect yet, but probably
  better than before
- Add optional hiding of VDC display
- Make double-clicking on the emulated screen switch fullscreen mode
- Alt+Enter will now also toggle fullscreen mode
- Added option to pause the emulation when settings dialog is open
- Remember not only the last directory but also the last file in file dialogs
- Show "Use Alt+M to disable mouse grab" in window title if mouse grab is
  active
- Support 'StartMinimized'/-minimized
- Added 'restore window geometry' to UI and commandline to allow users to apply/
  ignore the last position/size of the window(s) stored in vicerc/vice.ini.
- Allow for 8 'analog' controllers on Linux
- Added Alt+Shift+F12 VICII to switch border mode in x64sc
- Moved the netplay settings from the 'File' menu to the settings dialog
- Added 'Host' root node in the settings UI, move Autostart, Monitor, Netplay,
  Snapshot/Event/Media recording directory and start-mode under that.
- Also move Host->Machine settings (CWD and JAM-action) under Host, remove the
  Host->Machine node.
- Use workaround for GTKFileChooser's "Select" button not being active when
  selecting/creating a directory.

- Several Keyboard mapping fixes:
  - Added keymaps for THE64 keyboard
  - Updated keymaps for pet graphical keyboard
  - Fix shift+z/y in german positional mapping (c64)
  - Some tweaks to symbolic keymap for german layout (plus4)
  - Some tweaks to symbolic keymap for german layout (c64)
  - Fix (some) plus4 keymaps
  - Added positional keymap for Swedish keyboard
  - Fix ctrl and cbm mapping (c128)


** macOS fixes
--------------

- VICE GTK performance on macOS is now excellent and we finally now recommend
  the GTK build over the SDL build.

- macOS bindist now relies on macports rather than homebrew. With macports it’s
  possible to build deps from source while targeting an older macOS version,
  which allows us to continue to support macOS 10.9+.

- Re-enabled the bafflingly disabled working macOS joystick code

- Actual macOS game controller device names are now listed instead of 6x “Analog
  joystick n”


** c1541 fixes
--------------

- Added some REL file support
  - support for REL files to the c1541 COPY subcommand

- Add subcommand to show dir entry of a file, and all side sectors.

- Add support for SEQ and USR files for the -extract command

- Renamed `zcreate` command to `unzip`. 'unzip' (dissolve a zipcode archive)
  sounds more logical than 'zcreate'. When we decide to also support creating
  zipcode archives, a proper name for that could be 'zip' or 'zipcode'.


** petcat fixes
---------------

- Added missing basic v4 tokens for cbmII


* Changes in Vice 3.4
=====================

We are still looking for dedicated maintainers for the Windows port, if you
want to help improving these and/or want to provide binaries, please get in
touch.

We also needs support in fixing the various keyboard mappings, please test the
keyboard in your favourite OS and port and report any problems.

We welcome dqh in the team, who will take care of the macOS port.


** General
----------

- Remove support for Syllable OS, SCO, QNX4, QNX6, SGI, AIX, OpenStep/NextStep/
  Rhapsody, Solaris/OpenIndiana and remaining traces of Minix, NeXT, SKYOS,
  UNIXWARE, Sortix

- Remove remaining traces of support for WATCOM, MSVC, OpenWatcom

- Remove aRts support

- Remove YUV rendering

- Remove generation of .chm, .hlp and .info files. Please use the .pdf or .html

- skip building x64 unless --enable-x64 is passed to configure

- do not use the new/experimental 8580 filters unless --enable-new8580filter
  is passed to configure

- update pattern generator for uninitialized ram. changed defaults so all
  raminitpattern tests pass.

- remove block device disk image (rawdrive) "support". in linux it was never
  needed (just use the device file) and on windows it was never implemented.

- added support for the IP232 protocol that was used by the long lost VICE1.19
  hack, and which is supported by tcpser for emulating DTR/DCD (carrier detect)

- various userport rs232 fixes

- always save gifs as gif89

- added a couple shift flags to keyboard maps to support virtual cbm/ctrl and
  mandatory pressed host modifiers. not all keymaps have been updated yet.

- ACIA IRQ fix

- create empty half tracks when mounting d64. fixes skew.d64

- new headless port that can be enabled by passing --enable-headlessui to
  configure. this can be used to build an emulator without video output, which
  may be useful for scripting.


** Autostart fixes
------------------

- Implemented autostart for tapecart images (.tcrt)

- Automatically change drive type when autostarting disk images that do not
  work with the currently active drive.

- Make AutostartRunWithColon default

- fixed autostart when memory hacks are enabled (plus60k, plus256k, plus4)

- make auto-starting from tape also respect the 'basicload' option, loading
  absolute by default

- when using a disk image to autostart .prg files, remove the .prg extension
  from the temporary file name

- many detail fixes that make autostart work as expected in all emulators and
  in all configurations (eg C128 in 80 columns or C64 mode)


** Snapshot fixes
-----------------

- More strict checking and more explizit error reporting


** 6510 fixes
-------------

- Accurate emulation of ANE#imm and LAX#imm "magic constant" dependency on RDY.
  All occurrences of unstable use are being logged now. LAX#imm "magic constant"
  changed to 0xEF, which makes the problem cases "spectipede" and "turrican 3"
  work.

- fix: reset should set the I flag


** VIC-II fixes
---------------

- Accurate emulation of the "VSP bug". Warnings about possible VSP related
  memory corruption are always logged, actual memory corruption is still
  optional.

- Fixed changing more than one colour register via monitor


** VIC fixes
------------

- new noise LFSR as reverse engineered by Lance Ewing.


** SID fixes
------------

- use model dependent floating output ttl values like in residfp


** Monitor
----------

- Support full expressions in the monitor conditional breakpoints.

- When deleting checkpoints, reset the index to 1 when there are no more
  checkpoints left

- Added 'RL' for rasterline and 'CY' for cycle in line to list of conditionals
  that can be used for breakpoints.

- in mc/ms commands show asterisk for 1s and dots for 0s, not the other way
  around

- adjust number of disassembled lines so the top line does not scroll out of
  the window when labels are used.

- Added "log" and "logname" commands to control logging to a file


** vdrive
---------

- added rudimentary support for CMD-style reading of the RTC

- respect error info in disk images (only when reading right now). Should trick
  some simple protections.

- report 65535 blocks free rather than 0 so that applications that query
  available disk space before saving work as expected, e.g. some BBSs


** C-64 fixes
-------------

- added support for MAX Basic cartridge, new CRTID 61

- added clockport device for rrnet mk3

- fixed reading of 'open' clockport, fixed io dump for clockport devices

- implemented support for cartridge hardware revision in the crt format

- When attaching an Easyflash cartridge image, replace the EAPI driver with the
  one for the flash chip VICE supports. This way EF images that contain a
  different driver (for whatever reason) will still work.

- various keymaps added and/or fixed/updated.


** C-128 fixes
--------------

- added proper C128D model type.

- various MMU fixes

- fixed broken memory mapping in C64 mode

- Completely rewritten VDC vertical handling code. VDC101 demo with it's
  vdc-split technique is now fully emulated. This rewrite attempts to emulate
  more how the VDC works internally, and how the video signal/screen react, so
  the border height etc is now more naturally handled.

- Various misc VDC fixes, e.g. show blank lines with certain register combinations


** GTK3 UI
----------

- Implemented "restore display" (Alt+r). Resets the active window to its
  minimal/natural size. Handy when stretching the window and then not knowing
  you can make the window smaller again with resizing that same window until
  it doesn't get smaller.

- Change double-clicking images in smart/diskattach dialogs to 'open' instead
  of autostarting

- added options to select rendering backend and filter

- fixed opening files with UTF8 encoded filenames

- Make the (VTE) monitor display on top of the emulated machine window when in
  fullscreen

- copy only used icons into the distribution, which drastically reduced its size

- Added keyboard debugging to the statusbar

- Added * (all files) filter to the fliplist attach dialog. This will allow
  people to use Pi1541 *.lst files at their own peril.

- Add proper statusbar messages when using the fliplist.

- Add howto about creating a GTK3-Windows cross-compiler on Debian with Fedora
  packages (aka FrankenVICE)

- only show the host keyboard mappings in the list for which we have a valid
  mapping, grey out symbolic/positional depending on what keymaps are actually
  available

- Move joystick settings to the joystick widget on the statusbar.

- Windows: add icons to binaries

- allow better control of the filter settings by removing tick marks
  of the sliders and adding spinboxes (6581+ReSID only)

- Fix the 'media recording' dialog to not show empty widgets when FFMPEG support
  is missing, show hint on compiling in FFMPEG instead.


** SDL fixes
------------

- make hotkeys only check left alt, which makes right alt (alt-gr) work in
  keyboard mappings.


** macOS fixes
--------------

- make open-gl work

- binary distributions, font support, GTK3 dock icon

- fix missing icon theme, fixed pdf manual generation, improved build
  instructions

- fixed macOS make bindist when building out of tree

- Added instructions for building and debugging using Xcode



* Changes in VICE 3.3
=====================

This release stabilizes and introduces the GTK3 UI as the primary user interface
for all major ports. For "lesser" platforms we still have the SDL1/SDL2 based
interface. All other user interfaces have been removed. RIP

We are still looking for dedicated maintainers for the Windows- and macOS ports,
if you want to help improving these and/or want to provide binaries, please get

- add a slot number before the literal name of a game-controller, which is less
  confusing when more than one controller of the same type is used

- fix parsing of the commandline with -config first

- added dutch to list of keyboard mappings


** Unix fixes
-------------

- the sleep function was not handling timer overflows properly, which happens
  every 4 seconds on a 32bit machine with nanosleep()

---------

- Add toggle button in x128 for the Go64Mode

- ignore 'dotfiles' in the fileselector on *nix

- added browsing inside disk and tape images.

- added pageup/pagedown/home/end key mappings, and support them in the menus,
  file-selector and text viewer

- Terminal- or UI based monitor can be selected at runtime in all ports

- added a hack to get rid of spurious keyup/keydown events after switching
  from/to fullscreen

- generate suitable fonts for the ui at startup, use some custom gfx for the ui.
  fixes the problem that the ui chars will screw up when the user selects a

  - fix display of literal key names for SDL2

- major rework of SDL2 video renderer to work natively with all supported
  graphics acceleration technologies (OpenGL ES, DX11, Metal, etc). Fullscreen
  support and resized windows now preserve aspect ratio properly on any screen

- SDL2 now respects "GL" filter mode. As a bonus it does so even when the
  renderer is not OpenGL.


** VSID (GTK3)
--------------

- Remember last-used-directory for the open file dialog
- Add drag'n'drop support
- Add HVSC support:
    * Support SLDB
    * Support STIL


** VSID (SDL)
--------------

- implemented drag'n'drop


* Changes in VICE 3.2
=====================

** General
----------

- New (experimental) GTK3 native port, this and the SDL(2) port will replace
  all other ports (which will get removed) in VICE 3.3 and onward.

- Handling of the `-keybuf` command now works properly for all emulators and
  RAM sizes.

- Fixed handling of LOAD"$$" with virtual devices.

- Fixed @CD, @MD and @RD commands for virtual filesystem devices.

- Fixed NEOS Mouse emulation.

- Call the new CIA "8521" instead of "6526A" (which is wrong) in the UIs.

- Added 4sid support.

- Fixed tape wobble.

- Erase timing fixes in flash core.

- Don't allocate sectors on tracks > 70 in the BAM of 1571 images.

- Ethernet emulation: fix register mapping in rr-net mode.

- reSID: fixed envelope bugs shown by testprogs/SID/env_test/.

- Fixed 6509 CPU port issues.

- Added support for TAP virtual network interface.

- Fixed drive clock overflow. Drive and host went out of sync on clock overflow
  (every ~4G cycles), which would break loading or custom drive code in the case
  loader/stuff is not idle during overflow window. Also drive would execute
  ~4G cycles out of sync, which made the emulator freeze for a while.

** Monitor
----------

- Fix monitor 'm' command buffer overflow.

- Added conditional on values in memory to breakpoint handling.


** SDL changes
--------------

- Cosmetic overhaul of the SDL UI.

- New drag'n'drop support for the SDL2 port(s).

- Fixed monitor display of printables with the 'M' (memdump) command.

- Fixed drive status display in statusbar.

- Added "advance frame".

- Disable the mouse pointer unless we really need it.

- Change MacOSX SDL menu key to F10 to accommodate old MacBooks etc.

- Change default menu key for sdl amiga based platforms to 'F10'.

- Added default hotkey files (with hotkeys similar to existing GUIs).

- Added various keymaps for use with keyrah in combian/retropie.

- Added controller mapping file for PS3 controller.


** Android changes
------------------

- Do not enable mouse emulation by default.


** Mac OS X changes
-------------------

- Reinstated the Cocoa UI's Video Settings dialog. Some of the controls
  don't work properly, but it's better than nothing.

- Added a PET model selection menu to the Cocoa UI.

- Fixed Cocoa UI's CPU memory window display. It still requires the monitor
  to be activated before it will show anything, however.


** OS/2 changes
---------------

======================

** General
----------

- Added x64sc, the accurate C64 emulator:

  * VIC-II emulation rewritten from scratch using results from extensive
    testing with newly written test programs on real hardware.

  * Emulation is done on a cycle by cycle basis combined with pixel exact
    dot clock domain handling.

  * Accurate handling of all possible in-line splits of VIC-II registers
    and graphics data.

  * C64 model and even individual chip revisions can be selected for very
    detailed emulation of their differences.

  * Equally accurate PAL, NTSC and PAL-N emulation.

  We believe x64sc is one of the most accurate C64 emulators at the
  moment.

* Changes in VICE 2.2
======================

** General
----------

- On autostart, do not change true drive emulation (TDE) anymore by
  default. The old behaviour can be switched on again by specifiying
  -autostart-handle-tde on the command line.
  There is one drawback of this behaviour: If TDE is switched on, an
  image attached must fit to the drive type set. For example, when you
  attach a .D81, you must have the drive type set to 1581, or the
  autostart will fail.

- Added automatic Warp mode during autostart. If this resource is enabled then
  VICE automatically enables the warp mode and then loads a file. After
  loading the warp mode is disabled again and then the program is started.

- Autostarting a PRG file can now be done in three different ways:

  * "Virtual FS": This mode mounts the directory where the file resides as a
    virtual filesystem on drive #8 and then loads the PRG via virtual drive
    traps. This was the only way of autostarting in previous VICE versions
    and is still the default.

  * "Inject to RAM": The PRG file is loaded from VICE directly into the RAM of
    the emulated machine. Then the memory setup of a Basic LOAD is simulated
    and the program is run. This is the fastest mode available but may lack
    compatibility as no actual load operation was performed in the emulator.
    However, no drive setup is altered during the operation.

  * "Diskimage": VICE creates a temporary new disk image and copies the
    contents of the PRG file onto it. Then this image is mounted in drive #8
    and the program is loaded from there. If TDE is enabled then the load
    operation is most compatible. The disk image stays attached until a new
    image is mounted.

- Improved PAL emulation is now available for Unix/Xaw XVideo mode, and
  AmigaOS. Only the YUV packed modes work, the planar modes still use the
  old code paths, though.

- Sound core has been reworked to enable lower latency of operation.
  Approximately 50 ms latency values are now routinely reached, and some
  people have reported that as low as 30 ms still works for them.

- New SDL port. See ReadmeSDL.txt for details.

- New win64 ports, both amd64/x64 and ia64 are supported (msvc compile only).

- New SDL based armle, mipsle, ppcbe and shle QNX 6.x ports.

- New SDL based M68k and sparc SunOS ports.

- New SDL based Syllable port.

- Remote monitor (in other words: TCP/IP interface to VICE monitor) added.

- Fixed non-6502/6510 CPU handling in monitor.

** C64/C128 changes
-------------------

- ReSID's resampler has been optimized with MMX assembly. Some long-standing
  bugs in resample-interpolate mode were also fixed.

- ReSID-FP has been optimized, too. It clocks the analog parts at half the
  rate now, which saves CPU during filter emulation especially for 6581 modes.

- Added SFX Sound Sampler and SFX Sound Expander emulation.

- Added EasyFlash cartridge emulation.

- Added paddle emulation.

- Added lightpen/lightgun emulation, currently only available for the following
  ports: SDL, GTK+, cocoa, win32/win64 and msdos.

  attached on the joystick port.

- Added support for the following userport joystick adapters: CGA/Protovision
  (normally only used on the C64/C128), PET (normally only used on the
  PET/CBM2), Hummer (normally only used on the C64DTV) and OEM.

** PET changes
--------------

- Corrected the joystick support, since the only way a PET can use a joystick
  is by a userport joystick adapter, the following userport joystick adapters
  are currently supported: CGA/Protovision (normally only used on the
  C64/C128), PET, Hummer (normally only used on the C64DTV) and OEM (normally
  only used on the VIC20).

** CBM2 changes
---------------

- Corrected the joystick support, since the only way a CBM2 can use a joystick
  is by a userport joystick adapter, the following userport joystick adapters
  are currently supported: CGA/Protovision (normally only used on the

  Emulator is controlled with the new control window. There disk and tape
  images can be attached by clicking on the image or dragging files there.
  Added the tape controls for the datasette and the status bar.
  Added a master volume slider.

- Added SyncDraw display mode that does temporal filtering of the frames
  generated by the machine (motion blur). This enhances the display quality in
  moving scenes if the machine frame rate does not match the display refresh
  rate (e.g. a 50 Hz C64 is shown on a 60 Hz LCD display)

* Changes in VICE 2.1
======================

** General
----------

- The VICEplus project has been joined with VICE. Thus, x64dtv is now
  part of VICE.

- We can be contacted via IRC: #vice-dev on libera.chat

- Added a more accurate ReSID engine using floating point math (ReSID-FP).

- Added support for the USB HardSID.

- PAL emulation has been rewritten and optimized.

- Fixed the ACIA 6551 emulation. (x64/x128/xcbm2/xpet/xplus4)

- Monitor commands help text is now translated too
  (in ports where translation is available at all)

- Monitor IO command now displays IO area even if it is currently
  banked out.

- GCR file handling (.G64) issues an error message if the .G64 does not
  have the expected outline. Before, VICE just silently ignored such
  files.

- IRQ handling fix

** C64/C128 changes
-------------------

- Fixed the digimax sound generation.

- Added the RR clockport disable functionality at $DF00.0. Allows
  to disable the RRnet.

- Improved REU compatibility and timing.

** C64 changes
--------------

- Added isepic cartridge emulation.

- Added Double Quick Brown Box cartridge emulation.

** VIC20 changes
----------------

- Improved the sound emulation.

- Fixed the lowest note bug.

- Improved VIC emulation (exact in-line color/reverse mode changes).

** C64DTV changes
-----------------

- New emulator.

** Unix changes
---------------

- XRandR fullscreen implemented

- Command line option `-fullscreen' is supposed to do something
  useful.

- Vsync code imported from win32 (based on openGL extension).
  see also doc/openGLsync-howto.txt.

- Vidmode (fullscreen support) is broken and therefore marked as
  deprecated. It will be removed in the next release if no-one takes
  responsibility to fix the broken code and is willing to maintain the
  code.

- PAL Emulation (new implementation, improved speed) should be usable
  again (it was broken on certain display depths).

- Log messages are always english.

- Only x11 keymaps will be installed when doing a 'make install'.

- MIDI cartridge emulation for x128, x64 and xvic.

** MS-Windows changes
---------------------

- Watcom generated executables are more optimized.

- MIDI cartridge emulation for x128, x64 and xvic.

- When specifying the target for the RS232 communication
  (Menu Settings/RS232 Settings), the target can be specified by
  name now. Before, you had to use the IP address.

- Fixed some minor errors with the RS232 communication via TCP
  connections.

- RS232 can use real devices now, too.
  To use this feature, you have to specify the COM port used in
  Settings/RS232 Settings like:
  \\.\com1: baud=57600 parity=N data=8 stop=1

  The characters after the colon can be used to specify additional
  settings for the COM port. The string must have the same form as the
  mode command's command-line arguments:
  [baud=b][parity=p][data=d][stop=s][to={on|off}][xon={on|off}]
  [odsr={on|off}][octs={on|off}][dtr={on|off|hs}][rts={on|off|hs|tg}]
  [idsr={on|off}]

  The above example specifies COM1 with a baud rate of 57600, no parity,
  8 data bits and 1 stop bit.

  Note that the leading \\.\ is used to distinguish between TCP/IP
  targets and real devices, thus, you have to use it.

  (Sorry, no fancy UI yet.)

- Color palettes are now completely configurable via system files.


* Changes in VICE 0.14.2
========================

** C64 changes
--------------

- A few VIC-II and CIA timing bugs have been fixed.

- The "sprite crunch" effect should now be emulated properly.

- Changes to $3FFF/$39FF in the video bank in the middle of one raster
  line do not affect the whole line anymore.

- Color of forced $FF DMA characters is now correct.

- The SpeedDOS parallel cable is now emulated.

- More accurate SID filter parameters when the sampling frequency is
  different from 44.1 KHz.

- The `TapeName' resource has been removed.

** VIC20 changes
----------------

- An annoying bug that prevented BASIC from working has been fixed;

- True 1541 emulation works again.

- The `TapeName' resource has been removed.

** PET changes
--------------

- Emulation of joysticks connected to the user port has been added.

** Unix changes
---------------

- The "change working directory" command displays the current working
  directory as default.

- A new status bar on the bottom of the emulation window displays the
  current speed and frame rate, and the status (i.e. LED + R/W head
  position) of the disk drive when the true 1541 emulation is turned
  on.

** MS-DOS changes
-----------------

- A bug that caused sprites to appear near the screen when the
  640x480 resolution was used has been fixed.

** Miscellaneous changes
------------------------

- A little timing error in the 6510 RMW instructions using absolute
  indexed addressing has been corrected.

- Much improved 1541 emulation: most custom write routines should now
  work.


* Changes in VICE 0.14.1
========================

** C64 changes
--------------

- A nasty CIA-related bug has been fixed.


* Changes in VICE 0.14.0
========================

** 6502/6510 changes
--------------------

- Several mostly timing-related 6510 bugs have been fixed (thanks to
  Andreas Boose's test suites).

** C64 changes
--------------

- Better SID (audio chip) emulation.  Now filters are emulated and
  waveforms are more accurate.  (Many thanks go to Michael Schwendt,
  author of SIDplay, for helping out with this and for providing the
  filter code and the SID wave tables.)

- Some CIA bugs have been fixed (big thanks to Andreas Boose for
  reporting them).

- The IEC bus recalculation has been made slightly faster (but you
  will probably not notice this, also because the true 1541
  compatibility improvements have made the emulation a bit slower).

- Some VIC-II bugs have been fixed (more big thanks to Andreas for his
  invaluable test suite).

- Disk/tape images can be "autostarted" from the command-line (with
  the new `-autostart' option) or at runtime (i.e. you can attach the
  image and let the emulator run and execute the first program on it
  for you).  This also works with `P00' and raw CBM binary files.

** VIC20 changes
----------------

- Fixed a small resizing-related bug.

** PET changes
--------------

- Improved/fixed keyboards on X11.

- New `PetModel', `VideoWidth' and `KeyboardType' resources.

- Added support for 2001, 4032B and 8096 PETs.

- Better CRTC emulation: R01 (line width) and R12 (control register)
  are honoured now.

** Unix changes
---------------

- Dispatching of Xt events fixed (there was a very stupid bug that
  caused event loops to do busy waits--argh!).

- Made WindowMaker-compliant (x64, xvic and xpet can now be docked).
  Now, could anybody please contribute cool NeXTish truecolor icons?
  :-)

- Better handling of window resizing.

- `configure' now uses Xaw3d only if `--with-xaw3d' is specified on
  the command line.

- The pop-up menus now work also if NumLock or CapsLock are activated.

- A private colormap is automatically used (even if `-install' has not
  been specified on the command line) if the emulator cannot allocate
  all the colors at startup.

- Increased portability: now compiles successfully on SunOS 4.x.

- Improved automatic frame skipping algorithm; it now gives a higher
  average frame rate.

- Different, possibly more usable, menu layout.

** MS-DOS changes
-----------------

- The contents of disk and tape images can be inspected before
  attaching them.

** Miscellaneous changes
------------------------

- The 1541 emulation is now more accurate (disk rotation is taken into
  account, but hardware formatting still does not work although we are
  not far from it).

- Safer handling for 1541 ROMs: a checksum is calculated, and turning
  full 1541 emulation on when no ROM is available does not make the
  emulator crash anymore.

- BZIP v2 support has been added (from Andreas Boose).

- Read-only support for various archiving formats (`.tar.gz', `.zip',
  `.lzh', `.zoo') has been added.

- The character ROMs are no longer built-in.

- Removed `.doc' extension from certain files in the documentation, as
  it confused HTML browsers.

- Useless Makefile target that caused problems with newer versions of
  GNU make removed.

- C1541 can now create disk images from Zipcoded files (`zcreate'),
  import Lynx archives (`unlynx') and execute DOS or UNIX commands
  (`system').  (`unlynx' and `system' have been contributed by Ricardo
  Ferreira.)

- Wrapping around $FFFF in monitor commands works now (beware: not for
  all of them, yet!).

- New, more usable, version of the `recomment' utility.

- Support for Simple DirectMedia Layer has been added.

- Character generator ROMs are not built-in anymore.


* Changes in VICE 0.13.0
========================

- Improved (now cycle-exact!) VIC-II emulation (big thanks go to
  Andreas Boose for helping me to improve it).

- More accurate 6510 emulation (emulates extra unused read accesses).

- Lower memory requirements.

- Complete MS-DOS port.

- Several CIA fixes.

- The VIC-I chip now emulates the reverse mode.

- Loading from tape handles the memory pointers correctly.

- Joystick emulation in the VIC20 emulator.

- Slightly better source code organization.


* Changes in VICE-0.12.1
========================

- The CIAs have been rewritten and are now more compatible and much
  faster (most of the games that ran much more slowly than usual with
  0.12.0 should now run at normal speed).

- VIC-II screen updates are now a little faster and also eat less
  memory.

- Disk images can now be attached in read-only mode.

- Gzip-compressed disk and tape images can be attached directly,
  without uncompressing them.

- The hardware-level 1541 emulation now supports writing to the disk
  through the VIAs, so that write patches to the drive ROM are not
  needed any longer. [please notice that this might not work with
  everything, as the emulation is not 100% exact]

- VICE can now be compiled also with the standard (0.8.0) joystick
  module (without digital joystick support, obviously).

- A little bug related to the right Shift key has been solved
  (courtesy of Bernhard Schwall).

- The numeric keypad can now be used to emulate diagonal directions
  too.

- The Linux audio driver also works on 8-bit sound cards.

- When a CPU jam happens (illegal opcode), the user can now choose
  between entering the monitor, enabling the XDebugger or resetting the
  machine.

- Implemented the new `skip' button in the XDebugger.

- Some little annoying bugs in the SID emulation have been fixed and
  combined pulse/sawtooth and pulse/triangle waveforms have been
  implemented.

- The automatic refresh rate setting works better when sound is
  enabled.

- The adaptive playback speed in the sound driver can now be disabled.

- Sound can now be turned off automatically when buffer overruns
  happen, and is automatically turned on again after a specified
  interval.

- AIX audio support has been implemented (courtesy of Chris Sharp
  (sharpc@hursley.ibm.com)).

- The sprite collision interrupts are more correctly triggered.

- A bad bug related to the sprite expansion register has been fixed.

- The video cache now handles sprite-background collisions correctly.

- A nasty bug that could cause VICE to hang has been fixed.

- Attaching floppy images to drive 9 or 10 no longer makes them appear
  in drive 8 when full 1541 emulation is enabled.

- Solved some problems with systems that do not have regexp.h (at
  least we hope so).

- GNU make is no longer needed to compile the PET and VIC20 emulators.

- The documentation has been updated.

- The `tounix' and `toiso' utilities have been added.

- The problem that made VICE die with an `alarm clock' signal on very
  slow or overloaded machines should now be gone.

- The file selector no longer dies if you type `~' with no `/' in the
  directory field.

- The file selector now has a "contents" button with which you can see
  the contents of a disk or tape image before attaching it.

- The X11 video driver automatically disables usage of the MITSHM
  extensions if they are not supported by the X11 server (even if the
  `mitshm' resource is non-zero).

- Some annoying REU-related bugs have been fixed.

- The MS-DOS version uses the Scroll Lock LED to emulate the drive LED.


* Changes in VICE-0.12.0
========================

Well, almost 90% of the emulation code has been rewritten (that's why
it took so long to have this release out), so it would be quite long
to list everything here.  Anyway, here are the most important new
features:

- New 6510 emulation, which is much faster and has (hopefully) correct
  memory fetch timings and exact emulation for all the opcodes.

- Completely rewritten video emulations, now much faster and more
  versatile: the window size can be doubled at run-time and the video
  cache can be disabled when not necessary.

- (Much) better VIC-II (C64 video chip) emulation, mostly rewritten
  from scratch: it can now handle most $D011 tricks such as VSP
  (Creatures and Mayhem in Monsterland work) and FLI; [yes, the silly
  sprite priority problems are gone]

- (Slightly) better VIC-I (VIC20 video chip) emulation (still
  incomplete).

- New SID emulator by Teemu Rantanen, with support for Linux, FreeBSD,
  Solaris and HP-UX (not all of these are stable, though).

- New CIA emulation with correct timing.

- Faster interrupt handling.

- Xaw-based GUI with popup menus and interactive file selector from
  the Free Widget Foundation.

- Hardware-based 1541 disk-drive emulation, that works with many
  custom loading routines.

- New resource handling that allows saving and loading of settings.

- MS-DOS port (no sound yet, UI almost non-existent).

- Better T64 handling (still buggy).

- Removed C128 emulator and RAM tester (sorry, we had no time to work
  at them).

- Much better Linux joystick support, that works with digital and
  analog joysticks with auto-calibration (courtesy of Bernhard Kuhn
  <kuhn@eikon.e-technik.tu-muenchen.de>); [it should compile out of the
  box now]

- Support for all possible VIC20 memory configurations on the command
  line (courtesy of Alexander Lehmann <alex@mathematik.th-darmstadt.de>).

- Added `extract' command to c1541 (courtesy of Gerhard Wesp
  <gwesp@cosy.sbg.ac.at>).

- Added configure script for easier configuration and installation.

- Overall better source code organization, that should make porting
  much easier; [volunteers, you are welcome!]

- Better keyboard handling (reverse polling is correct now).

- The REU works.

- Several other bugs fixes and improvements we have lost track of.


* Changes in VICE-0.11.0
========================

- The CPU in x64, xvic and xpet is now 2 times faster on average; :->

- The VIC-II steals the correct number of cycles for bad lines and
  sprites, and correctly fetches the video RAM, so that FLD and other
  effects involving bad lines are now emulated correctly.

- The interrupt handling and the CIA/VIA emulations have been almost
  completely rewritten, thus dramatically increasing compatibility and
  reliability.

- The VIC-II sprite-sprite and sprite-background collision register
  emulation is (much) faster.

- The Read-Modify-Write bug of the CPU is correctly emulated when
  accessing the VIC-II register $D011.

- D64 and T64 can be directly attached (T64 in x64 and x128 only).

- A bad bug in the handling of the I/O registers of the 6510 has been
  fixed.

- The ADC and SBC decimal mode has been fixed.

- Various bugs in the 1541 error channel emulation have been fixed.

- The 1541 emulator and the standalone c1541 program support the Rx:
  (Rename) command and the Sx: (Scratch, delete) command now handles
  wildcards correctly.

- The infamous keyboard problem which caused key events to be lost
  when refresh was > 1 has been fixed.

- A IEEE-488 interface emulator has been introduced (emulates the
  original one) in x64, x128 and xvic.

- The xdebugger functionality has been improved (this part is still in
  the experimental stage, though).

- The `-8' and `-9' options allow to attach diskimages as drive #9 too.

- The Unix FS driver (Unit 11) has been improved, so that it supports
  the command/error channel and wildcards properly; moreover, new
  FS-specific commands (mkdir, rmdir, chdir) and errors (`permission
  denied' and `directory not empty') have been added.

- The VDC emulation in x128 supports variable character and screen
  size and bitmap mode as well (monochrome only and still under
  development).

- Some minor bugs in the VDC emulator have been fixed.

- The MMU implementation in x128 is much more complete, with true (not
  hard-coded) shared RAM and memory configuration support.

- A nasty bug which caused x128 to crash when changing speed and
  enabling/disabling the video emulators at runtime has been fixed.

- The Linux joystick has been fixed (it did not work at all in 0.10.0).

- The monitor `set' command no longer accepts ambiguous variable names.

- A new `hjoyport' variable/resource allows the user to choose the port
  for the hardware joystick (Linux only).

- Sun64 is no longer supported (if you need it, download x64-0.3.1).

- One thousand other little bugs have been fixed.
