# LEGO Racers: an N64 source reconstruction in progress

> LEGO Racers is an N64 source reconstruction that splits a user-supplied, hash-matched ROM with splat and builds C and C++ source alongside assembly-backed functions. Its configuration recognizes two ROM hashes and generates region-specific build files.
