ACN file

ACN files contain PCN file data.

We assume this is a kind of onboard Archive file go 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 'Top Hunter' is known to use this file type.
