== Overview ==
ARC files are archives. Containers of compressed files compressed with LZ-10 (more compression methods might be available).
This is very similiar to NARC (the DS archives).Found in [[BCMA|manual files] compressed with LZ-10

(Starts with 0x10 and followed by uint24 of the uncompressed file size). * Each file's end is padded to 0x10 besides the last one which ends with EOF.
