Data blocks for storing compressed raw graphics for animated map tiles. Data for a given map tileset is found using the Map Data: Tile Animation Characters Pointer Table.

Portions of decompressed data are pointed to by Tile Animation Properties entries.

Format

Data for each map tileset is individually compressed. See Compression Format.

Tilesets with no animations are all the same 24 bytes, 8 repetitions of E7FF00 followed by the FF terminator. (This is simply the compressed format of 00 repeated 8192 (0x2000) times.)

Decompressed Format

Each entry, once decompressed, consists of an unstructured block of up to 256 tileset characters, each a 4-bits-per-pixel 8x8 SNES graphics tile (sometimes referred to as a "minitile" by EarthBound modders). See Tileset Character Data Decompressed Format.
