Hello yes i have an iso 500 mB nbastreet but i was wondering if i can continue to rip it more to be about 200 mb?

probably take out some music videos or sound fxs or buy the game

how do i do that?

u need vcdromx something to extract the iso and this tutorial on how to rebuild iso http://www.psp-spot.com/forums/index.php?showtopic=1880&hl= you can also take out dummy files and do some reaserch on shrinking iso's
