So i was playing Disgaea 2 and i tried turning it on sleep mode. But for some reason it froze and turned off and then when i turned it on there was a error screen and it became default again.And whenever i try to play a PSP Iso there is a error screen saying 80020321.(For some reason PSX Eboots work) NOTE: I use 5.03 Chicken CFW3.5. Help would be appreciated and thanked. Thanks in advance as well.
