ok first of all you get the game enhancer so you don't have to mess with opening up your psx and maybe even messing it up. PLus the swap trick is Really Really simple anyone can do it. You have the real game in and you turn on your psx. The enhancers menu pops up. BTW the game enhancer doubles as a game shark. The disk will stop spinning and this is where you take it out and put in the back up. Then all you have to do is go to start game and it loads up. Very Simple! Since you already have the Game enhancer you don't have to go out and get the Mod chip because some games does detect the mod chip and they won't play.
