Someone found the ARK file structure, not sure if it applies as this is from MLP'S ARKs...
4 bytes - number of files in archive.
4 bytes - metadata offset
4 bytes - seems to be always 01000000
12-(metadata_offset-1) - compressed data (files compressed and/or encrypted one by one)
Metadata_offset-endoffile - encrypted metadata
64 bytes - filename
64 bytes - subfolder name (ex. 'folder/')
4 bytes - offset in ark archive
4 bytes - uncompressed file size
4 bytes - compressed file size (if equals to uncompressed size then not compressed)
4 bytes - encrypted file size (or zeroes if not encrypted)
4 bytes - timestamp
16 bytes - MD5 hash of the file
4 bytes - extract the file? (01000000 or 00000000)
=>168 bytes for every file in archive
Oh, and here's Win8's base version of the file. http://www.filedropper.com/0000iaadatadx
, "DX" I guess is Deluxe (Windows 8), Android uses "and" and iOS uses "ios". https://www.dropbox.com/sh/0b1mne4z4tcd ... d5FVsw2xaa
someone made a program with its source code to decompress them in MLP but it doesn't work for this game, the XXTEA metadata key (4F943201A15B02004F943201B5889900) is the EXACT SAME as MLP for BOTH PC AND MOBILE (IDK IOS)... https://www.dropbox.com/sh/0b1mne4z4tcd ... TjxP7P/Bin

Another tool, but doesn't work, says the ARK version is bad...
UPDATE: ARK Archiver cannot decrypt metadata of the MLP city builder as of some update, IDK when it was updated filedropper.com/mlpandroidark.
