Hey gang, I hope some of you can help me. A few years ago I had read up and learned how to play SNes games on my PSP using my copy of GTA. Although I could play roms and emulators and such, I could not play ISO's, but that was fine, I was happy with that. If I remember correctly, at that time my Motherboard didn't permit me to play ISO's on my memory card or to downgrade the Firmware to do so. I think I had OFW 2.70 or something at the time. No higher then 3 point something, but I digress. One day my nephew wanted to play a game on my PSP and updated it. I was screwed, everywhere I read, my motherboard and newer firmware wouldn't permit it, so I gave up trying to play emulators and such. A few years past and I upgraded it here and there, and today it's now at 5.51. A few days ago I decided to check up and see if things had changed, but I've been searching the net now for a few days to no avail, so these forums seemed to be a good place to ask for help directly. So here goes... Is there anything I can do with my PsP now? To help you guys help me better, this is what I have and this is what I know. I own a PsP which I believe to be a 1000, IC1003 model with firmware 5.51 update Version 3.80. I've heard of a Pandora's battery, but I cannot purchase one over the internet.... but I read somewhere that I could make my own. Presently I have the one default battery and the one 4gb Memory card to work with. I'd love to be able to play Super Mario again or maybe even be able to play ISO's now! I would appreciate any help anyone has to give me.
