Contrary to all the nagtive reviews that were posted here, my product worked properly and very well with no issues. I had used this device to activate hundreads of cheats on my games and they all worked!! The only game that wouldn't work with this device was the wwf no mercy which has a black cartridge. This product is worth the money and is completly durable as it lasted with me for over 3 months. Sadly I lost my product as I got older but I might get myself another one because it still remains entertainning and durable :)

despite not being supported anymore because interact was bought out by intec.this is a great tool for not just cheating but for varius other things such as enabling hidden weapons that you can't unlock on some games.if anyone still plays n64 i would recommend Game Shark to everyone who can have any use with it.Note Using Your Game Shark on a game for more then a hour oftenly can overheat your Game Shark And reduce it's life span and render it unusable.

My ten-year-old son thought it was great for the first twenty-four hours that it actually worked. On day two it didn't matter what game he used it on, it simply wouldn't work. He was very disappointed.

At first i didn't know how to use this but once i figured it out we had a blast. I am trolling Amazon for old games so I can put the GSP to good use. Thanks

A great tool for really scraping up some old worn out games., but... hence the title and the fact that it's kind of archaic now, some games tend to wig out when certain codes are entered, most notably with Resident Evil 2... other than that, it's awesome.
