fireemblem7u: a matching decompilation of the GBA Fire Emblem release

fireemblem7u reconstructs the USA/Australia GBA release of Fire Emblem as C source that rebuilds a SHA-1-checked ROM. The author reports byte-matched game functions, while scripts extract graphics, music and other data from the player's ROM; a separate host build runs decompiled C on macOS.
