ACN files contain PCN file data.

We assume this is a kind of onboard Archive file to save constantly loading the data from CD.

How this data is used is not yet fully known. We currently assume data is stored in the program ROM space and then moved to the correct place as needed. It is not known if this is handled by the bios or game at present.

The game 'Art of Fighting' is known to use this file type.
