I've been having problems while speedrunning Pokemon Yellow. The last run I did had stutters, massive input lag, the game holding a direction even when I press a different key (like moving right even after I stop holding the key, it's not just one tile either but rather it keeps going for a few tiles or bumps into a wall), inputs being eaten even when I press A 10 times only one of them is registered. I don't believe it's the keyboard having issues because I can play other games just fine without ever experiencing such problems, it's only when playing on the pokemon yellow rom. Is there any way to fix this issue?

Which emulator are you using?
