okay so i have CFW 4.01 M33-2 and i was wondering if i could upgrade it to CFW 5.00 M33-1 without a pandora battery or a magic memory stick, is that possible, if so can someone please tell me how to do it?

Another thing i need help with is finding a GBA Emulator that works and a GBA BIOS Image so i can play the roms i have.

And Finally could somone tell me what PSX means?
