I found that PS1 Quake 2 did crash occasionally when loading new areas but I was able to finish it just by taking a save state as a precaution before the end of a level. The crashes occurred intermittently. Best version of Quake 2 in my opinion.

@Boa are you using the standalone mupen64plus or lr-mupen64plus?

Okay so I got Digimon World working, but now the sound is about 98% non existent. Every now and then I'll here a Digimon make a sound or the text box chimes but mainly it's just silence.
