PSX Game downloads?

Do the PSX games if converted to CSO or ISO work here on the PSP? I have All Final Fantasy's since 6 and I was trying to get them to work on my PSP but most of the time they just crap out on me so I decided to try this site. Just curious if anyone has gotten them to work on a PSP at all... THANKS!
