- Most content of the rom is contained in a zip (named "vfs.zip") (the application likely contains an anti-tampering since you cannot load the game with the content of the zip being edited)
- Script are in compiled LUA, you can check the TrackManiaDS-Reversed github repository where the decompiled scripts are available
- The rest of the content are basic Nitro file
- File is split into sections, indicated by "D:" which are present every 0x100 (up to the custom maps)
- Replays are saved as raw binary files
| Byte Range | Information | Data Type |
|---|---|---|
| 0x00 - 0x04 | Header (always is "04 00 00 00") | UInt32 |
| 0x04 - 0x08 | Unknown | UInt32 |
| 0x08 - 0x10 | Unknown | UInt16 |
| 0x10 - 0x14 | Always ends in "00 00" | UInt32 |
| 0x14 - 0x18 | Always is "01 00 00 00" | UInt32 |
| 0x18 - 0x22 | Unknown | UInt32 |
- Maps (InGame) are 20x20x20 blocks, they're 506 bytes in the save file (Custom maps starts at 0xD00)
(for the following example, the starting offset is 0xD00)
| Byte Range | Information | Data Type |

| 0xD02 - 0xD18 | Map Name | Unicode, but it has other characters in between, i do not know what they're used for |
| 0xD1B - 0xD1F | Time Stamp | UInt32 (Seconds from January 1st 1935) |
| 0xD21 - 0xD30 | Seperator | Seperate Map Metadata to Map Data |
| 0xD31 - 0xD33 | "üÿÿ" | Unknown use, always present |
