The Game Genie Encoder/Decoder is a simple program which can decode and encode game genie codes for Nintendo, Super Nintendo, Genesis, Game Boy, and Game Gear game genies.

Two versions exists, a Java version and a C++ version. They are nearly identical, although the C++ version using Qt looks a little nicer. Both versions should run on any system, though we presently only have Windows binaries for the C++ version. Linux binaries are expected soon, but the source is available if you want to compile it yourself.
