You didnt configure the back button to any of psp's buttons so for example if you enter the in game options menu you cant back out of and softlock yourself
Alright I compiled it and it works. I first tried the enum (0x020000) which didn't allow me to use the menu and got stuck on the clock.
I deleted the prx file from the original, changed VOLDOWN to HOLD and compiled it. I turned on my psp go now...
IT WORKS!!! thank you as a fellow shrek hands psp enjoyer i was tired of shutting down my console!!!! works on both psp 2000 and 3000 ive installed it to both.
