The GameShark was an unlicensed cheating device made by InterAct (Datel?).
The GameShark was available on the following consoles:
- Nintendo 64
- PlayStation 1
- Game Boy/Game Boy Color
- Game Boy Advance
- Sega Saturn
- PlayStation 2
- Nintendo GameCube
- Nintendo DS
The GameShark Pro for the Nintendo 64 has a couple flaws.
- The poor design of the GameShark will sometimes brick.
- Some games lock-up when you exit the memory editor.
