Runs perfect including videos after following pcm720's instructions. Works with Proton 5.0, not 5.13. You need the 32 and 64-bit vidreszr.dll files added to mf-install. I changed the OS for the wineprefix back to Windows 10 following the protontricks install of dotnet452, since that's where I sourced the media libraries from. Past the first 2 dungeons now with no problems.
