Im kind of short on money and thought it would be cool to get games for free. i have a 2 gb memory stick duo and really have no idea what a pandora’s battery or magic memory stick are. Can someone please help me?

November 30th, 2008 at 2:24 am
OK. reading what most of you have written this pretty much sums it up.
A. YOU NEED TO HAVE PANDORA BATTERY TO HACK PSP (YOU CAN NOT USE CUSTOM FIRMWARE WITHOUT IT)
B. YOU NEED TO HAVE CUSTOM FIRMWARE TO PLAY .CSO’s and .ISO’s (downloaded games and movies or backups)
C. Join ww w . pspmod . co m (put it together) read the forums, read the rules, then post questions be patient and read what others have asked because perhaps there problem pertains to yours or the two have the same solution. Wish you the best of luck
