# fzgx: a matching F-Zero GX decompilation

> F-Zero GX reconstructs C source for the GameCube game's main.dol and REL modules, comparing builds with retail files. Its tools extract and unpack main.rel from the user's disc image, while unmatched functions are linked from that copy; the author reports roughly 30% of code matched.
