persona 2 issues

Anyone else have any? My copy crashes sometimes randomly in a regular fight, and all the time on the first boss fight... the random crashes in a regular fight didnt start occuring till after i crashed in the boss fight, but that could have just been chance... either way, im not too happy about not playing... anyone have either a good copy going and got past that point? or same boat as me?

*EDIT*
Got first the first boss fight, hasn't crashed since... However, there still are minor graphical glitches goin down places, but hey whatever. As long as I can still play.
