To use this save file you need to:

• Disable Steam Cloud saves for now.
  
• Navigate to
  %APPDATA%\SEGA\smt3hd
  There will be folder with just numbers as a name, open it, your save files will be located in it.
  
• Make backups for your saves.
  
• Replace your SMT3HDDATA.sav with one you've downloaded.
  
• Load save slot 15.

Also, walkthrough on save file you've downloaded was made on Chronicle version of the game. I dont know if there will be any problems if you dont have it, so just to be sure, go get it, its free :)

To get 100% compendium completion, you need to fuse the only demon that is left on this save, which is Vishnu. You can fuse it with Raphael + Skadi, which will be already in your stock.

After loading save slot 15, you will be located in Shibuya, so just go straight to Cathedral of Shadows and fuse Vishnu. Sometimes, achievement may not pop up, if thats the case, navigate to Demon Compendium → View.


There should be 100% completion sign and achievement should pop up.

Dont forget to enable Steam Cloud saves again :)
