These files are intended for XSEED's PC port. Simply copy them to the appropriate folders and you'll be good to go.

The mp_9999.arb file necessary for loading the map's contents has been provided for your convenience.
The file was removed in this version, but a decrypted copy of it from the Vita version works fine.
All other aspects of the map already existed in this version; it just needed the .arb file to tell the game to load the map's model and the debug menu.
