Ok, I started with a 2.6 fw PSP then I upgraded to 2.7, then downgraded to 1.5 then upgraded to 3.03 OE-A then upgraded to 3.03 OE-B.
I converted 3 of my umds into csos then made a folder in the root of my psp named ISO and put 3 different compressed csos inside my ISO folder.
When I goto Game>Memory Stick on my PSP nothing is there. I tried making an iso folder in the Game150 folder and then Game folder.
I tried using devhook to launch the cso and it detected that they were there but I can't figure out how to launch the darn things lol.
Any help getting these isos to run on the regular 3.03 OE-B fw or running on devhook would be greatly appreciated.
EDIT: Oh yeah and I'm using a TA-032 psp
