ARC file (Hey! Pikmin)

.arc files in Hey! Pikmin are standard ARC files, but only work with specific tools. In addition, the content inside does not really have a "type", so if you extract an ARC file's content, you will have to add extensions yourself if you want (like .bflim).

In Hey! Pikmin these files are usually compacted inside .z files, and usually have texture images (.bflim files) inside more often than not.
