SugarboxA new version of Sugarbox, a relatively new Amstrad CPC emulator for Windows, was released. The main feature of the new version is the support for various CPC emulator disk image formats (e.g. HFE of the HxC floppy emulator or RAW from kyroflux), precise Z80 emulation (according to Kevin Thackers timing test bench) and some other features.
Be sure to test the new version of the emulator and download the latest version from http://sugarbox.free.fr.

Changelog:

  • [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
  • [General]: Added sound for disk drive
  • [General]: Fix copy/paste for english/spanish/danish
  • [GUI]: Added a feedback when loading tape/disk/SNA/SNR
  • [GUI]: Added a preliminary debugger, with Register edition, breakpoints, flags
  • [Joystick support]: Fixed diagonals not supported with some joypads (now, games should be far more playable!)
  • [Memory]: Fixed the configuration : 64k computer no longer have improper PAL
  • [Settings]: Fixed some nasty bugs preventing the keyboard settings to work

Kyuran just released the source code of his Nintendo DS Amstrad CPC emulator CrocoDS on GitHub.  It is heavily based on WinCPC by Ludovic Deplanque. In the repository you can find the source code for version 2.0 of CrocoDS, which was released in 2007. He also released a version of the CrocoDS emulator for iOS.

After 4 years Richard Wilson released a new version of his great CPC  and Plus emulator WinApe. There are a lot of changes and enhancements for the emulation, but have a look at the huge changelist below. You can download it from the WinApe homepage and at the end of this post.

Here is the complete changelist for the new version:

  • Changed CDT/TZX Standard block timing to match specification.

  • Improved row and column highlight and removal especially in full screen mode.
  • Breakpoint Window Condition editor resized with window.
  • Breakpoint Condition form now validates the condition when Ok is clicked.

  • Added Timers and associated window. These are controlled using breakpoint condition functions timer_start and timer_stop.
  • Added a number of variables to breakpoint conditions (eg. MODE, palette_select).
  • Ensured all breakpoints evaluate even on single-step and/or if another breakpoint triggered first.
  • Improved breakpoint condition function parameter count checks.

  • Forced emulator to full size if full size AVI is required.

User Interface

  • Stopped F8 key from entering debug mode while currently stepping over an instruction.

Sugarbox

A new version of Sugarbox, a new Amstrad CPC emulator for Windows, was released. The main feature of the new version is the support of online libraries like CPC-Power and Amstrad.eu. Another interesting feature is the support for black frame insertion, which will provide a smooth scrolling on 100hz capable displays.
Be sure to test the new version of the emulator and download the latest version from http://sugarbox.free.fr.

Changelog:

  • [General]: Optimisations (Emulation is about 15% faster)
  • [General]: Generic Joystick are supported through Direct Input. 2 Joysticks can be used, in the order they appear in the os. Work with Xbox controler, as well as standard usb joystick.
  • [SNR]: Add feature to watch SNR file (playbacks) – Preliminary
  • [Z80]: Fixed timing issue in interrupt following some opcodes
  • [Z80]: Fixed incorrect R increment for DD CB and FD CB instructions
  • [FDC]: Fixed « Format » command. Now, a Format command from discology (for example) produce a disk that is correct.
  • [FDC]: Fixed the MSR, that was not handled correctly. This fix Bobby bearing and Camelot warriors original dsk.
  • [FDC]: Fixed the Step Rate Time computation, which was twice longe than expected
  • [FDC]: Fixed behaviour with SK bit and deleted sectors (making Nigel Mansell works)
  • [FDC]: Fixed how read track over the index hole works. The current sector is finished,then the command is ended (fix Skyx)
  • [eDSK]: Fixed an incorrect behaviour with non formatted tracks on some dump. This prevents Bobby Bearing (UK) (1986) (CPM)
  • [Original].dsk to crash when trying to load
  • [eDSK]: Fixed some rare problematic case with offset-info datas
  • [CT-Raw]: Fixed write bug when multiple revolutions exists (which somewhere shifted what’s written, leading to CRC error). Fix « Le maitre absolu » in ct-raw format
  • [Memory]: Fixed a bug in the PAL, preventing SymbOs to use full memory.
  • [GUI]: Fixed missing space and enter for Autotype
  • [GUI]: Added a PAUSE feature, accessible via menu or the « Pause » key on the keyboard
  • [Z80]: Fixed a rare bug that can lead to potential unwanted deadlock with HALT command
  • [TAPE]: FAST loading enabled : If a tape is read, refresh are cut, so speed can be 2 to 3 time faster.
  • [Display]: SDL2 lib is now used. Fullscreen option is now better, as it can be fully configured. Also, black screen insertion for 100hz display can be used for buttery smooth scrollers
  • [Display]: Screen size and position is now more correct
  • [Display]: Screenshots are now better (and without any toolbar)
  • [Printer]: A really basic printer is now plugged ! You can see print result in the PRINT directory. (no graphical printing is done, only text)
  • [Online libraries]: Preliminary integration of CPC-Power and Amstrad.eu online libraries.
