Two days ago I couldnt burn toast, today I am burnig psx games with ease. I ran into a problem though. I copied Fear Effect 2, which is on four disks, and Im still using the old swap method, where you wait for the sony screen and throw in your copy. That works fine. The question is.. When it comes time for the switch to a different disk..what do I do? I also wanted to know what a patch is, and if there was any way to copy and play a ps2 game without modding. If any of you guys have a link to a tutorial or info I would greatly appreciate the help. Thanks in advance.
