I am just wondering if i do buy a psp i have this plan. But i am worried it will go wrong.
1. buy a new psp and downgrade the firmware to 1.5.
2. put my .gba .nes files on my psp.
what i am asking is is it that simple? would i have to put an emulator application on the psp and then run the .nes and .gba files of the emulator?
And also when is there anyone who can say that you can play N64 games perfectly o0n a psp?
Also once you have downgraded is there any risks? Can you update it back?
