Hi /vp/
I'm looking to get my friend into Pokemon, i read up that Heart Gold is easiest for new players (he wont play the GBA ones for some odd reason) so i decided to emulate it for him.
The game runs ok for an emulator but the real problem is that it goes to black screen or freezes often. What is the best way to fix this issue?

Pic unrelated, the only pokemon related pic i have
