This article describes some technical aspects of slots for custom track distribution maintainers.
Original Mario Kart Wii
The tracks of Mario Kart Wii are internally addressed by slot identifiers beginning with value 0. The game uses integers (at least 31 bit unsigned) to identify a track:
Slots Hex | Slots Dec | N | Usage |
---|---|---|---|
0x00–0x1f | 0–31 | 32 | Original racing tracks (T11–T84) |
0x20–0x29 | 32–41 | 10 | Original battle arenas (A11–A25) |
0x2a–0x35 | 42–53 | 12 | not used |
0x36 | 54 | 1 | Galaxy Stadium |
0x37–0x3a | 55–58 | 4 | Special scenes like Winning run demo |
0x3b–0x41 | 59–65 | 7 | not used |
0x42 | 66 | 1 | Maybe reserved. |
0x43 | 67 | 1 | Online Protocol: No track selected yet |
0x44–0xfe | 68–254 | 187 | not used |
0xff | 255 | 1 | Online Protocol: Random selected |
There is a total of 206 (12+7+187) free slots in Nintendo mode.
CT-CODE
CT-CODE (or CT-Code; an abbreviation of Custom Track Code) is an extension of Mario Kart Wii. CT-CODE was developed by MrBean35000vr and Chadderz for their CTGP Revolution. The name CT-CODE was created by Wiimm, when he implemented CT-CODE support in his SZS Tools.
The main purpose is to allow more than 32 racing tracks in one distribution:
Slots Hex | Slots Dec | N | Usage | |
---|---|---|---|---|
0x00–0x1f | 0–31 | 32 | Original racing tracks (T11–T84) | |
0x20–0x41 | 32–65 | 34 | Custom tracks | |
0x42 | 66 | 1 | Maybe reserved. | |
0x43 | 67 | 1 | Online Protocol: No track selected yet | |
0x44–0xfe | 68–254 | 187 | Custom tracks | |
0xff | 255 | 1 | Online Protocol: Random selected |
CT-CODE uses the free slots and overrides arena and special slots to get space for 221 custom tracks in addition to the 32 original racing tracks.
LE-CODE
LE-CODE (or LE-Code; an abbreviation of Leseratte Code) is an extension of Mario Kart Wii. LE-CODE was developed by Leseratte. The name LE-CODE was created by Wiimm, when he implemented LE-CODE support in his SZS Tools.
The development of LE-CODE is split into 2 phases:
- In the first phase, only 217 custom tracks are available. Besides these custom tracks, 32 original racing tracks + 10 battle arenas + 4 random selections are available. These is a total of 263 slots, 7 more than allowed by the online protocol (256). This is only possible, because battle arenas share slots with custom tracks.
- In Phase 2 LE-CODE will change the online protocol to support more than 8 bits. At the moment, 12 bits (4027 possible custom tracks) are planned.
