Global tileset data. Each byte represents a tileset/palette entry for a sector of 8x4 tiles, starting at the top-left corner of the map.

TTTT TPPP

The first five bits of each entry is the tileset, and the last three is the palette, so you have 32 global tilesets, and 8 palettes.

Entries are arranged by sector rows, so given that the global map is 32 sectors wide, a table index can be generated from a sector x,y coordinate (starting from the top left sector as 0,0), using the formula table_index = x + y * 32.

Note that the global map is 32 sectors wide by 80 sectors tall for a total of 2560 entries.

So very stubbly.
This page is rather stubbly and could use some expansion.
Are you a bad enough dude to rescue this article?
