Or any other GBA emulator. I have a PSP-2000 running custom firmware 5.00 m33. I saw a previous topic discussing the Gpsp Kai 3.3 Test 2 Build 13 so I went ahead and downloaded it. There aren't really any instructions so I just put the emulator in the Game folder along with GBA bios and a rom. I did all this only to get the corrupted data message when I tried to start it. I've tried other versions of gbpsp and had no luck. Some versions show the bootable icon and then just end up crashing when I try to start it. Am I doing something wrong or is this a known problem? I've tried searching for a possible solution on google and came up with nothing. Thanks in advance for any help.
