Oh ya you might want to open 'Windows Media Player,' max out the volume slider, and then close the window. So the mp3 won't be really quiet.

1.1 fixes a bug causing the shortcut to open with the default program for mp3s instead of Windows Media Player.

You need to also have the PapaNier.exe in the game directory. Download from here= https://www.nexusmods.com/nierreplicant/mods/13
This only works with PapaNier v1.0
