Overview
This table contains map layer dimensions and alpha values. The table has a 12-byte dummy header that can be ignored (but should be left untouched).
Field listing
- 00-03 (04) = [ A ] Bitfield
- 04-0F (0C) = Unclassified data
- 10-13 (04) = [ B ] Layer 1 info
- 14-17 (04) = [ C ] Layer 2 info
- 18-1B (04) = [ D ] Layer 3 info

00 | [ A ] [ ? ]
10 | [ B ] [ C ] [ D ]
Alpha
It's unknown exactly how these values work, but they do influence how the map layers blend together; for example, the 'spotlight' layers in the Drago Plateau caves (maps 462-464) have special values.
Layer info
Each map has three layers. The 4-byte layer info includes the dimensions of each respective layer.
- 00-00 (01) = Bitfield
- 0x07 = (Width - 1), in units of 16 tiles (units of 256 pixels)
- 0x38 = (Height - 1), in units of 16 tiles (units of 256 pixels)
- 0xC0 = Unclassified data
- 01-03 (03) = Unclassified data
