ICN (FM Towns) refers to a set of icon image formats apparently associated with FM Towns computer systems.

Three formats have been identified -- see the Identification section below. The "ICNFILE" format seems to be the newest, and the most common.

More research is needed, e.g. to figure out the names and relationships of these formats.

Identification

One format starts with ASCII "CRI-FUJI".

Another starts with "CRI-FJ2 " (with a trailing space).
