EarthBound/Map Data/Compressed Tile Arrangement Data

This is a sub-page of EarthBound/Map Data.

Data blocks storing arrangements of four-tile-by-four-tile chunks for map tilesets. Data for a given map tileset is found using the Tile Arrangement Pointer Table.

Terminology note: In EarthBound modding, these four-tile-by-four-tile chunks are often referred to ambiguously as "tiles", while the individual 8x8 pixel tiles making up the tile chunks are often referred to as "minitiles".

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