For the future PSP games:
Yoshihiro and WAB are proud to bring you The First Firmware Trickz for Gamez that need Firmware 1.52 to run on your PSP and Cant Run UPDATER 1.52 or 2.0
The System think it's a PSP v1.52 ,v1.0 ,v2.0 even if its a v1.5 or 1.0.
Download it (at your own risk!) here.
Success! My PSP now thinks he's got firmware 2.00 and i can still run any homebrew i want.
Didn't test it on "2.00 dependent" games yet, since i have no such games
