Slot Usage
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 15 bit unsigned) to identify a track:
| Slots Hex | Slots Dec | N | Nintendo Usage | CT-CODE |

| 0x00–0x1f | 0–31 | 32 | Original racing tracks (T11–T84) | |
| 0x20–0x29 | 32–41 | 10 | Battle arenas (A11–T25) | 34 custom tracks |
| 0x2a–0x35 | 42–53 | 12 | not used | |
| 0x36 | 54 | 1 | Galaxy Stadium | |
| 0x37–0x3a | 58 | 4 | Special scenes like winningrun_demo | |
| 0x3b–0x41 | 59–65 | 7 | not used | |
