Each entry is a (little-endian) SNES address pointer to a group of tileset palettes located at offset [[EarthBound:Map_Data:Palettes|0x1A7EA7]]. There are 32 such groups, each of which contains varying numbers of palettes. In addition, each of those palettes hosts 6 subpalettes.

Table mapping between tileset numbers (from the Global_Tileset/Palette_Table) and map palettes for that tileset.

Format

Each entry is a (little-endian) SNES address pointer into the map palettes ($DA7CA7 or ROM offset 0x1A7EA7), representing the start of the block of palettes for a tileset. Entries are indexed by tileset number (from the Global_Tileset/Palette_Table), so the pointer for a particular tileset can be found using the formula palette_pointer_address = $ef10fb + tileset_number * 4 or palette_pointer_offset = 0x2f12fb + tileset_number * 4. There are 32 valid tileset numbers, giving the Palette Pointer Table a total of 32 entries and 128 bytes.
