Basic Structure

12 bytes of unknown things
1 byte of gamemode (0-single, 1-coop, 2-race, anything else - unset)
19 bytes of unknown things
128 chars of title
18 bytes of unknown things
966 bytes of tiles (1 byte per tile, see tiles below)
80 unknown bytes
28 * 2 bytes of object index (2 byte per object see object index table below,
 position determines object, value determines object count)

the rest of the file can be split into 5 byte chunks
(id, param1, param2, param3, param4), see param table below

Offsets

0x0C: game mode (possibly an integer or short value) 00 - Single Player 01 - Coop 02 - Race 04 - Unset
