Mario Kart 64

This work-in-progress decompilation of Mario Kart 64 pursues historical and educational elements within the game found via taking it apart and putting it back together. Inspiration to do so not only emanates from the game's hardware and technology but also its immensely positive effects on the cultures and families of nearly every nationality.

This repository does not contain assets. Compiling requires asset extraction from a prior copy of the game.

It supports and builds the following versions:

ROM Output	Revision	SHA-1 Checksum
mk64.us.z64	USA	579c48e211ae952530ffc8738709f078d5dd215e
mk64.eu-1.0.z64	EUR 1.0	a729039453210b84f17019dda3f248d5888f7690
mk64.eu-final.z64	EUR 1.1	f6b5f519dd57ea59e9f013cc64816e9d273b2329

Building

Build instructions located in the API docs
See also, the comprehensive API and documentation which includes an overview of the code-base while also discussing significant concepts, features, and modding.

Current State

The code-base may change significanty overtime as naming and documentation continues. The code-base is shiftable.

Some menu textures are compressed using a format called tkmk00. A byte-matching compressor/decompressor does not yet exist.
