PSX protector

[Kaiser_God]

Hi everyone
I am looking for a program that can "burnproof" a copy psx game. You see, I copy games for my friends but I get really mad when they copy the copy and sells the "2nd generation" copy to make money. I feel used because I'm kind. Can anyone give me a link to a good, strong psx copy "burnproof" program that I can download? I will really appericiate it.
Thanks for looking and for your assistance.
Bye
