F-Zero X: an early US N64 decompilation

F-Zero X reconstructs parts of the US Nintendo 64 game in C, alongside assembly extracted from the user's ROM. Its build extracts a user-supplied Z64 ROM and produces a ROM with a published SHA-1 target. The author describes the codebase as early research and says its output is not yet suitable as a general modification base.
