I have benn trying to find a way to play homebrew on my psp without a modchip i have tried alot with editing a 1.50 eboot so the psp thinks that it is a version 3.00 but its really a 1.50 as soon as it is editing i reckon that the sony's encryption and signiture is corrupted as soon as it is edited. if someone knows that signiture it would looks like epsilon and the U.P team will be fairly annoyied with the amount of work theyve done .
