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 12 courses online.
This guide was originally published at the M3 WIKI, which is now deleted and forgotten. The information in this guide was retained using an old M3 WIKI 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.
What You Need
- The Mario Kart DS ROM
- The Retail version IPS Patch or the DEMO version IPS Patch
- An IPS Patching Program
- For a custom hack you will need a Hex Editor
Please note: the guide was written for the Retail IPS patch and not the DEMO IPS patch. Hexing the DEMO patch will be similar but not identical to the steps contained in this article.
Applying the IPS Patch
The IPS patch replaces the first 12 courses in the online course list (of the 20 available) with the courses not normally available for WIFI.
- Make a physical back up of your ROM
- Click the Apply IPS Patch button. Select the IPS patch by using the program's browsing window
- Select the ROM to patch
If the above image appears then your ROM has successfully been IPS patched.
Hexing a Custom Track Hack
The track list can be edited to simply include your favorite 20 courses with a hex editor program. The WIFI list cannot be made longer than 20, so no matter what you have to leave 12 of the courses off your list. However, you can still race on those courses if your opponent chooses them.
Open the modified ROM in a hex editor. Go to 0x00004C34. The value here should be 0C (which is hex for 12). This is the number of tracks in your customized list. Change it to 14 (hex for 20). This will allow you to change every course in the WFC track list. From 0x00004C64 to 0x00004C6F, you should find the string "0C0F111317181A2021232526." This is the 12 new tracks. Change them, and the following 8 bytes (up to 0x00004C77), to adjust your track list.
Below are the values for all tracks in the game, along with their internal names. Grand Prix courses not normally available are marked with asterisks, followed by the Grand Prix courses name in brackets. The other courses are either battle arenas or incomplete tracks and playing them on WIFI is not recommended as they may crash the game.

Frequently Asked Questions
- How do these courses get picked?
Sadly even if you choose a "locked" course, you have to hope that yours gets chosen in the luck of the draw.
- What problems are there with the locked tracks?
Most play just fine except for some minor graphical glitches. The cannons in Airship Fortress and Waluigi Pinball do funny stuff when you see people go through them, but the gameplay is unaffected. In airship fortress you cannot use projectile items when you're on the airship itself. In the levels with other vehicles, the cars won't start moving until all players a synced up and the countdown starts.
- Why won't this load, file is corrupt?
The IPS patch will change the header of the ROM. Acekard's AKAIO and Bliss firmwares will fail to load the ROM as it will be seen as a corrupt file. To fix this run ndstool from the command prompt as 'ndstool -f gamename'.
- Will save files work with this patched ROM?
Yes, save files will work just fine. Most users who make use of the Track Hack do so for online play only. These users may choose to make use of a 100% unlocked save file. This way they can quickly game with all known vehicles.
- Can Nintendo detect the Track Hack?
The Track Hack simply sends a request to the DS on the other side asking it to load a MAP not previously allowed. Nintendo does not detect this or attempt to block any users, just as they do not block any WIFI ROMs running from Flash Kits. Have no fear when you game and enjoy the Track Hack.
