Stuck on a level? Looking for more game lives? Don't run around like a  headless chicken--hack your way to freedom! TheGameShark Proadds new  life (or lives, as the case may be) to your N64 carts, allowing you to play with  infinite health, lives, ammunition, and all the hidden characters locked away in  the programmer's vault of fun. The simple interface displays available  preprogrammed codes for thousands of games. New codes and games can be added on  the menu system (using the high-score-style letter and number scrolling for each  character--tedious, but effective). Just stop by theGameSharkWeb site  to grab the latest codes, often available just days after a game's release. A  new feature allows any Metnick wannabe to hack codes of their own.
