Mario Kart DS Hidden Tracks Online

From M3 Wiki

How to play on normally hidden Mario Kart DS Tracks on the Nintendo WiFi Connection

Normally, you can only play 20 of the 32 courses available in Mario Kart DS online. However, the guys at GBADEV have found a way for those of us with M3s and other such devices to patch the game to let us choose any 20 courses of our choice online.

[edit] Items Needed

1. DS + M3 + Pass/Flash/WifiMe
2. Mario Kart DS ROM
3. Extra Track IPS file (Here)
4. An IPS Patching Program (Here are some)
5. OPTIONAL: A Hex Editor (Here are some)
6. OPTIONAL: RETAIL Mario Kart DS cart

[edit] Steps

1. Take your Mario Kart ROM and apply the IPS patch using whatever program you prefer.
2. OPTIONAL: Edit the patched rom in hex to customize the track list you get during wifi play.
3. Now you have a choice. If you want to use your user name/save game data from your retail copy, then copy the rom over as is to the SD/CF card. Otherwise, copy it with the game manager using normal boot, no trim.
4. If you are using your retail save data, put your copy of Mario Kart in your DS (flashme users) or into your passme and your passme into your DS.
5. Boot up the M3 and start the ROM in DEMO mode (start, not A to load it) to use retail save data, otherwise press A to load game manager patched rom.
6. Play online!

[edit] Customizing the Tracklist

Thanks to Hypershell

Open the modified rom in a hex editor. Go to 0x00004C34. The value there 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 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.

Here are the values for all tracks in the game, along with their internal names (from Parasyte). Grand Prix courses not normally available are marked with *'s. Also, I added the menu name for all Grand Prix courses in brackets. The other courses are either battle arenas or incomplete tracks, I do not recommend trying them as they may crash your game.

[edit] Questions

What exactly does this do?

The patch by default replaces the first 12 courses in the online course list (of the 20 available) with the courses not normally available in wifi. This 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.

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.

Why do I need the commercial cart?

It has been found that you don't. You can copy the patched/hacked rom over with the game manager software and play it like any other nds rom. You may use your retail copy of MK to play with the save game data from the cart. This is very handy to those of us who've built up quite the standing on our retail games and want to play the extra courses without starting over on a flash device.

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 don'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 AKAIO and Bliss firmwares will fail to load the ROM as it will be seen as a corrupt file. To fix this run ndstoolfrom the command prompt as 'ndstool -f gamename'.
