[mrpoope]

i have bee using back ups for a while, but im having trouble with my ea back ups. i have a v0 ps2 and i am using the swap method. swap magic 3.1 i belive for both dvd and cd. all my games will boot, except those that are EA sports. I have tried NBA Jam, and NBA street Vol 2. Can someone please help me out what i need to do to get these games to boot. i belive i need a patch, but i am not sure how that works the guides are a bot confusing. is that a method that goes something like this

BOOT DISK - PATCH OR BIN FILE - GAME BACK UP ?

can someone help me out ??

thanks !
