MAKIchan Graphics

MAKIchan Graphics (MAG; also spelled Maki-chan) is a raster graphics format that was used mainly in Japan. It may be associated with MSX computers. It's been accused of having an overly complex compression scheme.

It is also spelled MAGIchan, but that is presumably a typo.

Identification
