Using r2modman on Windows

This is a guide made for Lethal Company but it’s pretty good so just pretend it’s for RoRR.

Run the game at least once, to make sure steam generates the wineprefix. Doesn't have to fully launch or anything, steam just has to try launching the executable.
Put the version.dll in the game files or use r2modman. This is done in the same way as you would on Windows.
Get protontricks on your system, and run protontricks 1337520 dxvk. Alternatively, if you know how to, run winetricks dxvk after setting it up to use the correct wineprefix.
Set the launch options to WINEDLLOVERRIDES="version=n,b" %command%

If the game doesn't launch after specifying the launch option, it might help to go into the game's properties and force it to use Proton Experimental in the compatibility tab.
