    Homebrew A5200DS - Improved

    So A8DS will play 5200 carts though it’s not custom tailored to it. I keep the 5200 separate because it’s always the red-headed stepchild of the larger A8 scene and the system deserves better. Sane reason I keep the MC10 MicroDS separate from DracoDS.

    ColecoDS - Improved

    https://github.com/wavemotion-dave/ColecoDS V11.0: 20-Aug-2026 by wavemotion-dave Added preliminary handling of undocumented flags X and Y for improved CPU accuracy. Fix for 64K 'Activision PCB' banking so that we correctly start the ROM running. Other minor cleanups and commenting as time...

    GimliDS

    That’s cool! I can certainly look into mouse support via the touch screen. I don’t think it would be too much trouble given that the X and Y positions are simply read from the SID chip which handles the interface. I’ll add it to the TO-DO list.

    Draco-DS - A Dragon / Tandy CoCo Emulator

    Okay... was back trying to debug the sound in Shamus and ended up re-working the sound driver. It didn't help Shamus but it's a big improvement in accuracy and now games like Demon Attack have proper sounds! I checked in a daily 1.6b build on my github site... still trying to figure out Shamus...

    Micro-DS ... a Tandy MC-10 Micro Color Computer Emulator

    Well... it's been a minute as the kids say! Almost a year since my initial release of MicroDS - a handheld MC-10 (and Alice) emulator running on a DS/DSi/XL/LL. https://github.com/wavemotion-dave/MicroDS Not a lot changed with version 1.1... I've added 60Hz 'true-sync' that synchronizes the...

    https://github.com/wavemotion-dave/DracoDS V1.6: 05-Aug-2026 by wavemotion-dave Improved accuracy on PIA handling (DDR and masking supported) - sound and keyboard reading more robust. More games read keys/joystick more correctly. Massively improved .DSK and .CAS type detection and loading. Use...

Gandalf DX now runs! Added new 'Autoload Search' option - allows seeking for large tape games like Guns & Gears...

    GimliDS

    @Tomtani1 - you're right! I just checked the code and I don't properly flush the file out until a new file is loaded or you quit the emulator using the 'Quit GimliDS' menu item. That's my mistake. I've just added the code to correctly flush the file immediately so you can now long-press the...

    GimliDS

    Either of those settings is fine. The only difference is whether the disk sound effect plays. I assume the SD card you have is not write protected. Other than that, I can’t think of a reason. As a workaround you could probably snap a Save State and restore it each time to bring back the high...

    GimliDS

    Thanks for the feedback! I just tried my copy of Jumpman.d64 and it seemed to write the disk just fine after getting a (pathetic) high score. The disk label on the keyboard should light up blue briefly on save. Make sure that in settings you have the emulator set to one of the "Write DSK"...
