Q: I need to buy Pandoras battery? or upgrade to 3.90 m33-2 ? Thanks
A: Yes you need to get Pandora's battery and magic memory stick. with that you can up grade too 3.xx m33 and play iso ( games you downloaded ) but you need to have custom firmware to make magic memory stick and Pandora ( but you can make the Pandora without custom firm ware but you have to open battery . So ask a friend to make you a pandora and magic firm ware memory stick or you can make it urself. heres where i learn all my hacking psp info and now im hacking psp at school for money hehe here you go. psp_hacks.com and go to forums and read because everyone asks this. heres a other link. http://www.psp-hacks.com/forums/about136070.html
