Detailed Description

Text on surface composed of 4bpp tiles, mapped in column-major order.

There are actually two chr4 systems. The difference between the two is the ordering of the tiles: column-major versus row-major. Since column-major is 'better', this is considered the primary sub-system for tiled text.
