Ok, so I just upgrade my PSP to 5.50 GEN-D2 and it won't run any of the games I bought from PSN like Half-Minute Hero, GTA: Chinatown Wars, Fieldrunners etc.
It will run UMD games perfectly.
Every time I try to copy a PSP game from my PS3, I get some error and it doesn't copy. Maybe the games won't run because the thing isn't activated?
I also can't download games from MediaGo.
Anyway to bypass this?
