HI, this is my first post in this forum. i read through the threads and did not find anything about this.
i currently got tekken dark resurrection and used devhook .44 to emulate firmware 2.71 to play it. i have a 1.5 psp from launch. i seem to have a problem now. the psp is stuck on firmware 2.6. i rebooted, took the battery out and everything but it's still 2.6. anything i can do to fix this/ any help is appreciated.
