    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"...

    Homebrew Stella-DS Improved

    This is the DSi version :) Though it also works on the DS (Lite/Phat) as well. RAM isn't a problem. I'm using about 3MB out of the 4MB on the DS and 3MB out of the 16MB on the DSi. Not sure what I'd do with more RAM. Now extra CPU speed would be nice... if I only knew how to program for the...

    Homebrew Stella-DS Improved

    https://github.com/wavemotion-dave/StellaDS 8.4 : 27-June-2026 by wavemotion-dave Fix for TIA rendering that fixes Aardvark and probably others. Fix for banking on Squish-Em-Deluxe (F8) so dummy read on RTI properly hits the hotspot. Hotfix for PAL rendering which was causing the LCD to...

    SugarDS - An Amstrad CPC Emulator for the DS/DSi/XL/LL

    I can confirm that it does not load correctly. I did try to debug it a bit a couple of months back... got nowhere. If I load the .dsk file it throws an unhandled OP exception. I did manage to load it on a PC emulator and create a .SNA snapshot past the loading screen and that snapshot will load...

    Homebrew A5200DS - Improved

    Been ramping back up on A5200DS in the past week - porting over some improvements from the other dozen or so emulators I've been working on. I've just checked in a test version 3.8a with some nice changes: 60Hz True-Sync. The emulation is now synchronized with the LCD display to avoid...
