i have a 512 mb memory but u can get a 4gig one now.... also i have 3 games at presant gta liberty citys rocky balboa and toca... umm i dunno what games to sugest
if i were u, i would get wormz for psp. (forgot the exact name) i dont own a psp, but i played my friends psp, and wormz was my favorite
Im playing madden 08 it's fun NFS Carbon lsot me I still play most wanted 5-1-0 The boxking game si fun too, also twisted metal , and socom
pspiso(dot)com is what I suggest! I got mine from a used psp store, downgraded it and I can get games within a couple hours.. I also have a 4gb stick.. It holds about 10 games or so, depends.. some get ripped, like madden 08, and only end up taking 160mb for the game. So if your smart, you might just take advantage of that website!
