# Kuru Kuru Kururin: functional GBA decompilation and PC port

> kururin reconstructs the European Game Boy Advance Kuru Kuru Kururin in C for functional rather than byte-identical behavior, and builds an SDL2 PC port for Linux and Windows. The author's reported tests run the original and rebuilt ROMs side by side through recorded input, comparing RAM, sound and video; the port loads game data from the user's own ROM.
