    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...

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

    Finally found my horizontal scrolling bug! For games that utilize the horizontal offset register, I had a bug that would not render odd-offsets (1,3,5,7) correctly (it would treat them like even offsets). This caused slight blurring/jumping in games that utilized them. This was most evident in...

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

    Hey guys... been working really hard this weekend on finally adding 60Hz True Sync display handling. If you've played Nintellivision long enough, you'll have noticed that when you walk down the corridors of Tarmin, explored the caves of Cloudy Mountain or wandered through the towns in TNT...

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

    I've been off on some wild 8-bit adventures most of this year but I've returned to bring some improvements to Nintellivision. NINTY-DS was the first emulator that I added a sort of 'Favorites' system but it has evolved this year. To that end, I've back-ported the most current scheme which...

    Homebrew Stella-DS Improved

    We already have an unbelievable PC Engine emulator courtesy of FluBBa. Even plays my beloved Gates of Thunder on CD! (via ISO image). I think I'll leave the 16-bit machines to more talented people :)
