Global Tileset/Palette Table
Game EarthBound

End Address 0x17B3FF
# of Entries 2560
Entry Length 1 byte (0x1)
Total Length 2560 bytes (0xA00)
Back to the ROM map

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. The actual usable number of palettes varies per tileset and can be determined by analyzing the distance between pointer values in the map palette pointer table.

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.

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