The Game Genie Encoder/Decoder program is a simple program to encode and decode game genie programs.
The interface should be fairly self-explanatory. Just select the system you are using (NES, SNES, Game Gear / Game Boy, or Genesis), and fill in either the raw code or the game genie code. The one you did not fill in will automatically be generated.
