Newbie here needs help or instructions

Hi people. Newbie here. I need help about the psx iso here in Romulation. I have downloaded 1 game here and I put it on my psp but it says on my psp that the data is being corrupted. Does all psx isos here in Romulation isnt compatible with the psp? I already have a popsloader here. But the iso I downloaded in this site appears to be corrupted. Please help. Is there any way to fix this?
