# Luigi's Mansion (3DS): partial ARM source reconstruction

> Luigi's Mansion (3DS) Decompilation recovers C source from the Nintendo 3DS release, with implemented formatter, startup, runtime and game-state functions. Its tools extract a user-provided decrypted dump, generate ARM disassembly and run headless Ghidra analysis; the main game entry remains unfinished.
