[cpc] SugarBoxV2 2.00.0 (Yet another CPC emulator) 14/04/2023

Sugarbox_1.99.2 17/11/20

• Continuous integration and version automatic generation (#30)
• CI and automatic version creation.

SugarBoxV2 2.1.1 (Yet another CPC emulator) 4/09/2026

New: DAP debugger for VS Code

• Added a TCP DebugServer (JSON over TCP) under Sugarbox/debugers/, with a full protocol covering registers, memory, breakpoints, snapshots (.sna), keyboard input, and hardware state (CRTC/GA/PPI/PSG/FDC/Tape).
• Integrated the amstrad-cpc-debug VS Code extension (new Git submodule).
• Removed the old DebugSocket and the partially-implemented legacy debuggers (cleanup).
• Added a pytest integration test suite (protocol, step, evaluate).

CPCCore

• New debug interface (IDebug): breakpoints, memory display, synchronous snapshot loading (LoadSnapshotNow) usable even while paused.
• Added the ED FF break opcode (RASM standard) and support for RASM debug chunks.
• Full rework of keyboard handling (Raspberry Pi keyboard support, function keys, real keyboard state exposed for tests).
• Renamed the debug interface so it's no longer tied to gdb terminology.
• Misc fixes: missing virtual destructor on IMedia, disk refresh on load via external command, temporarily disabled WAV/TCN regression tests.

CI / Build

• Fixed macOS build (AGL framework removed from the newer Xcode SDK → dylib stub workaround).
• Bumped to Node.js 24 and actions/checkout@v4 across all workflows.

Sugarbox v0.29 22/01/2017  

• Complete PLUS family support: 464+, 6128+, GX4000. All ASIC functions are supported (making modern demo like « CRTC3″ or « Eerie forest » functionnal).
• SNA v3 is supported, with BRKS chunks (breakpoints generated by RASM or Winape)
• Various fix on full screen management (should not crash anymore)
• Various fix on DSK management. More dumps should be analyzed correctly
• IPF support: Generated IPF file should be more reliable (no more crash with Samdisk or DTC from kryoflux)
• Joystick support is better
• Sound have been reworked.

Sugarbox v0.28 30/06/2017  

• [Gate Array]: Fix mode changing: Imperial Mahjong now looks better !
• [Expansions]: Add support for the Playcity
• [Expansions]: Add support for the Multiface II cards.
• [Z80]: Complete recoding of the Z80 core. It now use the real M and T states, and handle WAIT states correctly. More accurate.
• [General]: ZIP support (only zip file at the moment) for tape and disks
• [IPF] : IPF created is striclty equivalent to the original dump (in term of MFM track)
• [IPF]: Minor fixes in IPF reading
• [DSK] : Fix some wrong behaviour. Dsk reading should be more reliable (and will no longer crash)
• [DSK]: Fix a bug in saving DSK file. It should no longer crash (anyway, if you can avoid using it, prefer HFE or IPF format !)
• [Emulation]: All peripherals are now running in the correct timings.
• [FDC]: Index detection fixed on Sector writing (Imperial Mahjong is able to save its configuration)
• [FDC]: Dump with missing tracks will no longer crash Sugarbox
• [FDC]: Fix wrong behaviour for double sided dumps that needs flipping of disk (fix altered beast double sided CTRaw)
• [FDC]: Fix wrong status than can set « Seek end » incorrectly in some cases

Sugarbox v0.27 27/11/2016   

• [Emulation] :Add some optimizations. MAX speed should be faster (about 100% gain from v0.26)
• [Emulation] :Remove memory leaks in IPF writing process
• [Config files] :Fix the ‘-’ and ‘_’ for french keyboard: « From scratch » now autorun properly.
• [Display] :Screenshots are fixed: No more unwanted black line at the top.
• [Dump support] :Fix the code used to compute multi revolution dump, to be more reliable (when a revolution is wrecked, dont use it)
• [FDC] :Lots of fix in the FDC: The ‘acid tests’ of arnoldEmu are almost all corrects now.
• [FDC] :Fix some bugs when reconstructing the tracks (fix some dump of « Le Necreomancien », and various CTRaw files also)
• [FDC] :The ‘Flip’ fonction (used to flip double sided dumps) is now working correctly. Double faces IPF are now working
• [FDC] :’10′ bits used for bit synchronisation can be in a smaller number: 40 bits are enough to consider the PLL as correctly fixed between clock/data bits
• [General] :Fix a deadlock that occurs when a command is used during a dump disk is read
• [General] :Fix the autotype feature: the feature is more relevant. Also, the « | » character is correctly rtanslated to ‘ù’ on french keyboard.
• [General] :Add a function to recording every frame into a screenshot
• [General] :Autorun feature is a bit more reliable (more rules added)
• [General] :Added some command line switches :
  • -sn xx (load xx as a Snapshot file),
  • -drivea xx to set xx into drive A,
  • -driveb (same for drive B)
  • -fullscreen to start in full screen mode,
  • -config xx to load xx as config file,
  • -command xx to run xx as basic command at start
• [GUI] :Fix the incorrect update of « Save as.. » menu when inserting a disk.
• [Multiface II] :Add preliminary support for Multiface II (no config yet)
• [PPI] :Rewrite most of the 8255 implementation. Now run the ‘acid test’ properly (when it have meanings)
• [PSG] :Correct lots of bugs (sound is now a LOT better, and digitized sound works correctly). Fix Dick tracy, Antiriad, Crazy cars 2, and probably a lot more !
• [PSG] :Also run the ‘acid test’ of PSG correctly.
• [Z80] :Support for NMI added

Renegade 1987, Taito

Sugarbox v0.26 5/04/2016   

This update is mainly focused on IPF and Disk support, but it includes also a debugger (rather simple at the moment, should be improved in the next releases). Z80 emulation is a bit better (all Z80 tests are now correct).

• [CT-RAW/IPF]: Native support of these two format. CAPSLib dll from SPS is no longer used. This will fix some non-working dump( due to bug in the lib).
• [IPF]: Add a SAVE IPF option. You can save your current disk in IPF format, to generate a 3″ disk. You can even write dump with weak sectors.
• [HFE]: Now it’s possible to save HFE file !
• [edsk]: Added some tuning to handle sector of header size lower than real size.
• [edsk]: Fixed some nasty memory overrun.
• [edsk]: Fixed the way of handling overlapped disk: « Corsarios (UK) (1988) (CPM) [Original].dsk » disk now run correctly. In fact, all dsk should now retrieve their original size of 6k/track
• [edsk]: Fixed support for ALLGAP dumps
• [FDC]: New paradigm: Weak bits are now handled by bit. Multi-revolution dump are converted to single revolution with weak bits data.
• [FDC]: Fix a bug with the SZ byte = 0 in read track command (this fixed « War In Middle Earth (UK) (1987) (CPM) [Original].dsk » dump)
• [Tape]: Add a delay when motor is on/off. This fixed « Last Mission »
• [Z80]: Interrupt mode 0 is partially fixed: It does nothing, but no longer corrupt the Z80 registers
• [Z80]: Fix some wrong behaviour of undocumented opcodes
• [Z80]: Add the undocumented ‘Q’ register used for Flags, and fix the SCF/CCF instructions regarding this register
• [Z80]: All Z80 tests from Patrik Rak, adapted to the CPC by Kevin Thacker, are now correct.
• [Display]: Fixed wrong behaviour for 100%speed with 100hz screen without black frame insertion: Speed was twice what was intendeed
• [General]: Add Autorun disk on insertion which try to guess the best file to run.
• [General]: Optimization: Everything is now running 60-80% faster than before
• [General]: Add a support for auto-executing BIN file (with AMSDOS header), through drag’n'drop.
• [General]: Fixed the Spanish configuration for 464, and added support for Danish keyboard.
• [General]: Added -fullscreen command line to enable fullscreen by default
• [General]: Fixed the « -command » option: In order to run a disc, just launch your command as Sugarbox -command run »disc » for example
