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 - 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) Build system - 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=yes), makes MP3-decoding support optional - Added --with/without-ogg-vorbis - Added --with/without-flac (default=yes) - 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 - Aadded 'rmdir' command - Aadded "verify" and "bverify" commands to compare memory with a file - Aadded optional address to the `screen` command - `chis` shows the cycle count as well now - Aadded option to configure the number of lines used for chis - Aadded 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(!) 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 VIC20 fixes - Added handling for 32k cartridge files that contain blocks 1,2,3 and 5. - Fixed megacart nvram addressing - External audio filter fix
