Gotta be honest here. Save states are miracles for NES emulators, SNES emulators, and Genesis emulators. They let you save without actually having to use an in-game save, which can often save you a lot of aggravation.

However, in the case of PSX emulators, save states are (more often than not) a bad thing. I have seen so many help topics on other forums about games getting buggy and crashing and all other kinds of issues, only to discover that loading from a save state is the root of their problem.

I can't say for sure that you would run into that problem, but if you did happen upon a save state and then discovered your game was unplayable, then you didn't really gain anything. So, my advice to you, sucky though it may be, is to just start over.
