U8 Archive

Archives, .arc, or ARC files are a common container format used throughout Sonic the Hedgehog (2006). Arc files can store a full file and directory-based virtual file system. Files may be compressed using zlib. In Sonic '06, the directories may be traversed, and individual files extracted and loaded into memory as needed.

Format

TBD.
