# Mario Kart DS: an incremental matching decompilation of the European release

> mkds-decomp incrementally reconstructs the European Mario Kart DS ARM9 code in C. Candidate functions are compiled with mwccarm, compared against cartridge bytes with relocation checks, and incorporated into a ROM rebuild checked by SHA-1. The author reports that unmatched spans remain original-byte gap objects during the partial reconstruction.
