Ok, REGULAR 4 wire modchips can be detected by new games and the game locks up. Stealth 7 wire chips cannot be detected by new games. Game Enhancers cannot be dectected either. Patches are usually for trainers, pal2ntsc converter, or non-anti-mod . .for people with a 4wire chip. But if you have a 4wire you can just use the action replay cd "free for download at megagames.com" and there ya go . . .
