It starts with 16 bytes of (yet) unknown function (try decreasing the value at 08h - makes part of the voxels invisible).
Then theres a part 768 bytes that's like a paltette, but it seems to be unused as changes in there result in nothing.
This is followed by 32 remap-tables (I think) each 256 bytes long. They tell the game which color to display (based on direction) instead of the "real" color (the one that gets displayed in the editor).
