PSP minis Issues on PS3 | PS3Blog.net
Having issues playing PSP minis games on the PS3, even after updating to firmware version 3.15? Don’t sweat it, the conversion process just started. All new releases from today will work just fine (they will be put under a “minis” folder on the XMB). On December 17th, Sony plans to have the conversion process finished and all games will work on the PS3 (though, you will have to re-download the titles).
