SugarBox autorstwa Thomas Guillemin jest, jak zresztą pełna jego nazwa głosi, kolejnym emulatorem mikrokomputerów firmy Amstrad-Schneider - CPC464, 646, 6128. Głównym celem jego rozwoju jest dokładne odwzorowanie pracy monitora wraz z nieznacznymi poprawkami w emulacji procesora Z80, w który były wyposażone flagowe konstrukcje tej marki.
Sugarbox v0.24 31 march 2015
- [FDC]: Read track handle correctly TC (Hercule, and ESAT software works again)
- [FDC]: Side changing is now correct: Game with only one side no longer crash if they try to access a second side (Dragon of flame)
- [FDC]: Fixed a bug if a sector CHRN is almost ok, when a read sector command is issued (Wild Street is now ok)
- [FDC]: FDC is more robust: Trying to load a random file as RAW will fail without a crash (hopefully)
- [TAPE]: RECORD function added
- [TAPE]: Added length of tape
- [TAPE]: Lot’s of rework on the WAV support: Now load more files, including « Skate Crazy », « Basil », « Footballer of the year II » without the « reverse polarity » trick.
- It mainly try to reproduce what’s actually in the CPC: Filters, gains, and so on.
- [TAPE]: User can now set the Tape position at wanted position (by clicking on the counter status bar). Also, a shortcut is added to set tape to wanted block, or last ejection position
- [General]: Added file extension if needed, when saving file (for CDT, CSW, WAV, DSK, SCP, SNA files)
- [General]: Fixed a memory leak (which should have no impact on standard use)
- [Memory]: 464 has now no PAL
- [Display]: Full screen is now available for Direct X 9 display. Also, a smart sync has been added, to sync the display @50hz with 100hz display
- [DirectX9 display]: For people who want smooth display, it’s possible to sync Sugarbox with your monitor. Display is smooth, but whole emulation speed is affected as well (typical 60 hz monitor will run at 120%)
- [DirectX9 display]: For lucky people with 100hz monitor, an option has been added, to insert a black frame between two frame. Whole speed is exactly 50hz, and display is really smooth.

→ [cpc] SugarBox 0.22 (Yet another CPC emulator)
Sugarbox v0.22 22 juillet 2014
Main fix is on the CAPSImg.dll use: I found a way to use it without making it hang. This fix lots of CT Raw files that previously used to crash Sugarbox. Also, be sure to use the 32 bits version of the DLL !
What’s new :
- [FDC]: Fixed a wrong behaviour on a read sector command: When an overflow occurs, do not stop the command until the end of the sector. (This correct some version of « Famous Five » game)
- [FDC]: Disk rotation is simulated, with a slight variation depending on the time and the current track. Also, more realistic acceleration of the disk is done (« Basun » now run without any trick)
- [FDC - HFE]: Add support for HFE files
- [FDC - Dsk]: Add various fix to make it more reliable
- [FDC - CT RAW]: When reconnecting last revolution to first, support track that does not contains IAM: Length computation is done using first IDAM
- [FDC - CT RAW]: Handle correctly CAPSImg.dll error, so no more memory corruption occurs on incorrect dumps
- [FDC - CAPSImg.dll]: Use a workaround to avoid crash of the lib that can occurs when image with weak sectors are read.
- [CRTC0]: Fixed an incorrect behaviour on VSync duration from R3 (Correct Druid 2 )
- [PSG]: Fixed a bug that can corrupt memory when a register grater than 15 is written
→ [cpc] SugarBox 0.21 (Yet another CPC emulator)
Sugarbox v0.21 20 juillet 2014
- A quick 0.21 version to correct few things about CAPS library: I made a mistake and incorrectly include it without the proper licence files. So, the 0.19 and 0.20 version will be removed. So, as it is intended to be used, I just change the way it worked now: If a CAPSImg.dll can be loaded when inserting a CT Raw or a IPS file, it will be used (otherwise, the disk will not load). Visit the Software Preservation Society for more details.
Other than this, here is what’s new :
- [CRTC0] :Add support for CRTC 0: Few demos may not worked, but lot’s of them do (including the impressive « Shadow of the beast » preview from Overflow)
- [CRTC1]: Fixed a little error in the CRTC, preventing « Chany dream 2″ from running properly.
- [CRTC]: Fixed a case where HSync falling edge is not detected ( Chany dreamend part 8 is now displayed correctly)
- [Display]: Fixed an incorrect behaviour of Screenshot function, that used to take incomplete screenshots
- [Display]: Adjust a bit position of the screen
- [SNA]: Fixed some bugs with snapshots that have VBL bit = 1 in the PPI.
- [SNA]: Fixed Vertical Adjust improper in snapshots
- [FDC]: Fixed a rare case where, in a Kryoflux RAW file, the index is missing from the stream (which caused a crash to occur)
