hello,

i recently have problems with my PSP 2000, it was 5.50 Gen-D2 at the start. i upgraded it in 5.50 GEN-D3 before installing the 5.50 Prometheus-3 and install the add-on to make it 5.50 Prometheus-4.. (with the help of a Video)

after i have successfully change my firmware from 5.50 Gen-D2 to 5.50 Prom-4. i have played The 3rd birthday.. i stopped playing it and just use my PSP for Music. But after a while, whenever i opened that ISO it always say "the Game could not be Started".

i tried DOWNLOADING OTHER Untouched ISO (and some PATCHED ISO) but it always says "the Game could not be started"

i never change any options from my VSH menu for that matter.

Please someone help me, i don't know much of experimenting my PSP..

PS: and regarding that PRO B-8 (latest Firmware) can it play ISO games (no UMD)?? and is it better than Prometheus-4??
