I got a PSPGo used today, it seems to work great. I put 6.60 official on it, then the 6.60pro light custom firmware thing. Once I restart the system, I run Fast Recovery and all homebrew works fine, like gPSP Kai, without any issues whatsoever. However, when I try to run any isos form the memory card or the internal memory, the game is recognized, and seems to launch, but it just freezes on black screen booting. The two games I've tried are Kingdom Hearts: BBS, and Legend of Heroes: Trails in the Sky, both of which supposedly are known to work on 6.60 pro cfw, according to several comments from the site I got it from. What the heck is wrong here?
