The G(ame) S(hark) H(ackers) I(index)
GSHI is a longstanding collaborative group of gameshark and action replay code hackers who have contributed many, many codes to the scene. Many people who use the gameshark and the action replay devices are unaware that the companies who manufacture and market those devices use websites and communities such as GSHI to produce and distribute the codes that cause the hacking devices to be as popular as they are.
