Sorry for the necrobump, but this topic is relevant for me. Which emulator will run the most games with the least bugs?
Do Gameboy Advance emulators play Gameboy Color games? It would be ideal to find an emulator that plays Gameboy Original, Gameboy Color and Gameboy Advance games. I'm aware that no$GBA plays Gameboy Advance and DS but I don't know if it's compatible with original and color games.
Let me help you with this friend.
bgb and Gambatte for Game Boy/Color games because they are the most accurate ones according to
this
Both bgb and Gambatte have an accuracy grade of 89.4% which is really high.
I can say that they are indeed very accurate because I use them a lot personally on a regular basis.
bgb as far as I know is closed source which is apparently a big turn-off for some but Gambatte is open sourced.
I prefer bgb as you can see
here,
here and
here as I made my own borders for it with authentic colors and all.
Plus bgb actually makes it so you can use the Game Boy and Game Boy Color bios files which Gambatte can't.
As for Game Boy Advance games I recommend VBA-M but don't recommend it for Game Boy/Color games, bgb and Gambatte makes a hell of a lot better job in that department.
As for Nintendo DS games, DeSmuME is the only one I can recommend since it have superseded no$gba since long. Although apparently it does have DSi support but for Nintendo DS games, DeSmuME all the way.
