Doom Gameshark Codes (USA, Europe)
This page contains Gameshark cheat codes for Doom (USA, Europe). If you're playing on an emulator you can usually input codes very easily by accessing a tab off the top of the toolbar. Anyone playing on a physical Gameboy will need to purchase a physical Gameshark device to use these codes.
