How to get Resident Evil Revelations 2 to work in Proton/Wine

Resident Evil Revelations 2 use WMP11 not WMP9 as the first game did to play its Cutscene, and since that is not part of Proton or Wine, you have to install it manually. First, you need to start the game in proton 5.0. Don't play. Just start it, so it creates the prefix folder in steam.
If you want to know how to install protontricks, you can check it here.

First, open the Terminal.

Then put this command in the terminal and push enter.

PROTON_VERSION="Proton 5.0" protontricks 287290 -q wmp11

I always use winetricks, but sometimes you can't because you don't have permission to do so, and that's where protontricks come in handy.
if you want to use WINEPREFIX, then Open Terminal and then put this command into the terminal.
WINEPREFIX=~/.wine winetricks wmp11
Depending on what you use, you need to edit the WINEPREFIX to the folder that you need to install it to, like RER's prefix folder or Wine folder.

It will download and install WMP11, and when it's done, the game should now show the cutscenes.
