I have a brand new PSP w/firmware 2.60. I downloaded 4 games. 3 have a firmware use lower than what I have and 1 has a higher firmware than mines. How will I be able to play these games on my PSP without going back and forth downgrading and upgrading? Is there an easy way? Also....is it possible to convert PSP games that were downloaded or on the original UMD disc into PC games?
