about roms please i need an answer

i ave benn proving since yesterday to play a lot of games in desmume but they start but i cant see then i cant see any image. somebody has an answer?

Post in the correct topic in future, moved.DSmume is not the best emulator, try No$GBA, and make sure you extract the roms from the rar file. Don't get your hopes up because many games cannot be emulated at this stage.

like looney said use no$gba it's better and it doesn't have those glitchy backrounds but some game might run slow
