I have tried compiling the NDS file with the roms, without the roms, just renaming the .ds.gba file as .nds... and i always get the "no roms found" message, even after putting NES roms in the same folder and the root folder... DOH!
i would like to try and get nesDS and SnesDS to work. SNEmulDS sorta works, but the sound is distorted on most games.
Nes ds works well, though the scaling is somewhat annoying, if you compile a rom, don't rename the file extension, just write the output rom through the gamemanager. As for snes, thats about as good as it gets.
