This article needs cleanup. This article needs to be edited to conform to a higher standard of article quality. |

Mega Drive version
Level headers
Level headers are 42 bytes each. They contain data needed to load their layout, objects, etc. Below is the format for a level header. N/A means that we yet don't know its functionality, however looking at their values it seems like them all are pointers. If a question mark (?) is in the description, then the content isn't confirmed yet. All palettes pointers are indices from some array.
Offset | Size | Type | Description | Compression |
---|---|---|---|---|
$0 | 4 bytes | Pointer | Object placement | RNC |
$4 | 4 bytes | Pointer | Collision layout | RNC |
$8 | 4 bytes | Pointer | Graphics for plane B tiles | RNC |
$C | 4 bytes | Pointer | Graphics for plane A tiles | N/A |
$10 | 4 bytes | Pointer | 32x32 mappings for plane B | N/A |
$14 | 4 bytes | Pointer | 32x32 mappings for plane A | N/A |
$18 | 4 bytes | Pointer | Level layout | N/A |
$1C | 4 bytes | Pointer | List of miscellaneous graphics to load | Custom, graphics use RNC |
$20 | 4 bytes | Pointer | Start position, checkpoint positions, etc. | N/A |
$24 | 2 bytes | N/A | Unused? (always $0000) | N/A |
$26 | 1 byte | Index | 1st palette | None |
$27 | 1 byte | Index | 2nd palette | None |
$28 | 1 byte | Index | 3rd palette | None |
$29 | 1 byte | Index | 4th palette | None |
Level headers locations
Those are the addresses for the headers of all the levels in the game. They point to the beginning of the header data, of course.
