    GimliDS

    Donations Welcome (but never required!) All of the emulators I've helped develop over the last 6 years are free to use. I tried to estimate the number of hours that have gone into these hobby projects - for sure more than 2000 hours of development total - including answering many hundreds of...

    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...

    Homebrew A7800DS - Improved

    Well... file this under keeping me humble. For more than a year now I've had a RAM decode issue in A7800DS that affected SUPERCART RAM games with RAM mapped into $4000. Basically I only allowed access to the first 4K of that. The bug crept in on v4.9 with my over-zealous optimization of the...

    ColecoDS - Improved

    It should really be that simple... at a minimum you need coleco.rom (exactly so named) in the place you keep your BIOS files - I keep mine in /roms/bios directory. The other BIOS files are not required but helpful to allow all the cousin systems to play properly.

    Homebrew Emulation Introducing Nintellivision - an Emulator for the DS/DSi

    With the introduction of the Intellivision Sprint, there has been a lot of new and custom artwork produced. That's been a boon to Nintellivision - I now have a lot of better artwork to make custom overlays from. If you haven't updated your overlay extras.zip package in a while, you will likely...
