A Mod Chip is hooked into your Playstation that bypasses the copy
protection and country lockout phase of the Playstation's
startup. With one installed, you can play CDR backups *of games you
legally own* and import titles.
Please note that the majority of rec.games.video.sony (myself
included) does not condone piracy or using "backups" of games you
didn't shell out for and don't own the original disc for. See section
3.15 for the reasons why you WILL lose in a court of law when dealing
with CDRs.
Mod chips also destroy whatever was left of your original
warranty. You have been warned.
