Mario Kart DS-Track Hack Information Guide
Mario Kart was released with only 20/32 courses available for online play. Thanks to talented users from the GBADev community, we have found a way for those of us using Flash Kits to enjoy the other 20 courses online.
This guide was originally published at the M3WIKI, which is now deleted and forgotten. The information in this guide was retained using an old M3WIKI link and the Internet's Way Back Machine. The guide has been slightly rewritten but the information and steps to hacking Mario Kart remain the same.
