To anyone that has an old Interact GameShark:

We cannot support any version of the Interact GameShark, period. For anyone who would like a rundown as to why:

Interact originally developed GameShark. They had their own encryptions, own software, and basically their own ways of creating the devices which made the GameShark popular.

January, 2003: Interact announced that, after much financial struggle, they filed for bankruptcy and shut their offices down. MadCatz, who has been looking into trying to find a way into the game enhancement market for some time now, saw this as an opportunity to acquire and continue the legacy of one of the best game enhancement products on the market. After much negotiations though, Interact was only willing to hand over the name, "GameShark", and the affiliated website (at the time), www.gameshark.com (which was still being supported at the servers of www.ign.com). This did NOT include any of the older product information, such as technical data, hardware, software specs, product designs or patents. All it gave us was the right to use the name "GameShark", and continue updates and maintenance on the website.

Since this was the case, the older GameSharks that Interact supported were gone. The original specs, software, hardware and technical data was purportedly taken down along with the company, although some have speculated that it could have been sold off to another company. Either way, MadCatz has never offered support for those older Gamesharks because, simply put, there is no one here who knows how they work.

The MadCatz GameShark uses a new code format, brand new code encryption, updated menu features... basically, a new GameShark built from the ground up. So now you know that MadCatz has ZERO support for the old InterAct GameSharks for ANY system. You can call or email tech support on GameShark, as long as you have a MadCatz GameShark only!

Thank you.
