I would look more into it myself but I'm strapped for time and don't know where to look lol.

This could go technically in the trading post as well but what I am asking for is, a PSX game capable of being played in a PSP, I know there is a method to change a PSX game so that it is playable on a psp, but can you simply obtain an image that is already converted? and how would you put it on a PSP? (consider I know nothing about PSP emulation)
