Hi I have a Devhook .46 that runs firmwares 1.50 to 2.71 and I wanted to play ff crisis core on my 1.50 psp but it requires firmware 3.70 or something. My question is can i upgrade my psp with the umd to 3.70 but then use the devhook to go back to 1.50 to play my emulation when I want? Is there any way to play the umd game without upgrading?
