I downloaded Birth By Sleep the other day, and I went to play it using this emulator (http://emulator-zone.com/doc.php/psp/jpcsp.html) but when I start the ISO, all I get is an error message saying that yhe file format is not supported ,
Birth By Sleep JUST came out and is unplayable on the current firmware on the PSP. And the PSP emulators have just started and aren't the greatest.
Ace is right. First of all, all the PSP emulators can barely even play God Of War. It only plays games like N+ and Bubble Bobble Pocket well. Second of all, Sony is getting tricky on AP patches. They made required online registration for Socom FTB3 and blocked KH: BBS with AP, which is causing CFW users to freak out. To the older PSP users, it isn't a big deal, you can just flash back to CFW whenever.
Well they have made a patch that is somewhat english that works in a modded psp with firmware so you can play bbs only if you get the files http://www.youtube.com/watch?v=bLQtzgjID1Y and have a firmware psp.
