CHAR (Metroid Prime 3)

This article is for the CHAR format from Metroid Prime 3: Corruption. See CHAR (File Format) for the other revisions of this format.

The CHAR format defines an animation character; together with SAND, it serves as the successor to the ANCS format from Prime 1 and 2, and contains much of the same data. The main difference from ANCS is that the file no longer contains multiple characters; instead, every character gets its own CHAR file, and any animation data shared with other characters is stored in SAND.
