Hey guys i know there are a lot of threads on this but theyre way too mixed up to find. I have a backup of guitar hero 2 and i am using FUJIFILM 16x DVD-R's I have swapmagic 3.6 and when i slide the card and put the backup in, it says not a valid ps2 disc. i have tried the "using the CD and original ps2 game" option, then it goes to the main menu with the memory card on it. ive been looking for an answer since the game came out...im on the verge of spendin 80 bucks on it. help!
