So today I downloaded desmume and I entered a rom, everything was working fine till I tried to speed through the beginning scene in Pokémon HeartGold, as soon as my fingers hit my keys my screen would shut off, if I hold any key down for more then a second it begins to turn my screen on and off over and over again, I don’t know if it’s my computer or what, any ideas on what I can do to fix this issue?
