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.

Number of palettes per tileset

The number of palettes associated with each tileset varies, but because the pointer table points to a contiguous block of palettes, all in order by tileset, and each palette is a consistent 0xc0 bytes, the pointer table values can be used to determine the number of palettes associated with each tileset. The determination can be made using the formula num_palettes = (tileset_plus_one_table_pointer_value - tileset_table_pointer_value) / 0xc0.

Note that, having no following entry, the number of palettes associate with tileset 31 cannot be determined in this manner. But it is known that tileset 31 has a full 8 palettes through observing the usage of those palettes in Magicant.
