Devil May Cry 3 Dante's Awakening Special Addition Help!

Okay. I appreciate Google for putting the game up for grabs, and also his instructions on how to get it out. But once I use 7zip to "extract" the files to their own folder, they're in weird format, Devil May Cry 3 SE.I00 and Devil May Cry 3 SE.I01. On top of that, the extraction says Devil May Cry 3 SE.I00 is broken. Redownloading the files don't fix anything, I can't mount the MDS File through Daemon, I can't run the game as an ISO, and im just genuinely confused.. Maybe I'm creating my own havoc, any tips?

Inform the uploader that the file is broken

You might want to try extracting with WinRAR first though, as a rule is 7-zip doesn't work for any reason then try WinRAR (free version is enough for that)

Normally though you would be able to just mount that via the MDS like you attempted to do, so long as the Devil May Cry 3 SE.I0x are in the same folder as the *.mds file
