MAKIchan Graphics

Revision as of 23:29, 13 August 2020

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

There appear to be three main subformats: MKI (or MAKI), MAG, and MAX. MAG is probably the most common. MAX is a slight variant of MAG, and uses a native MSX color model known as YJK.

It is also spelled MAGIchan, though that might be a typo.

Identification

MKI files begin with the ASCII signature "MAKI01A " or "MAKI01B ".

MAG and MAX files begin with "MAKI02  ".
