Game suddenly stop working

Hello everyone, I have already installed the rom for the specific emulator. but suddenly when i open the game the game suddenly hangs and not work, but the music is working. May i know what seems to be the problem for this issue? Thank you.

need more information. but off the top of my head I suggest checking your video driver (settings, far left menu) switch it and try again. alternatively it could be the game specific configuration but without more detail we cant really help.
