i can't get it to work. everytime i tried to load a snapshot of digimon ds but it doesn't seem to work. anyone know what's the problem?
You can't use the ROM or you can't get a screenshot of it? If the former are you using an emulator or a flash cart?
is the snapshot feature (you right-click the emulator then choose save state) used for getting screenshots or is it like the one in VBA where you press shift+F1 to save the game.
I think you mean to say savestates, not snapshots. If you're using No$GBA, I don't think they ever added savestates yet, but I could be wrong.
No$GBA does indeed not saves states, you have to use the in-game save function and pray that it works.
