New to burning and need help!

[rack]

My younger brother has a problem with ruining his games for his U.S. PSX and I heard that back-up copies can be burned. I've tried using a MAC using Toast and they will not work. Well, now I hear about Mod Chips that will fix the prob. I don't really want to break open the case if I don't have to . Now I hear of these "patches". Can someone let me know how to do this using a "patch"? And if using a patch do I need to use a Mod chip?

Any help for this beginner would be appreciated.

Confused...as usual...
