Primary listing of what locations on the global map use what tilesets and palettes.

Format

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 (T) of each entry is the tileset, so there are 32 global tilesets. The last three (P) is the map palette and is specific to the tileset, so there are up to 8 palettes per tileset.

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. A table index can be generated from a tile x,y coordinate using the formula table_index = x / 8 + y / 4 * 32.

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