(Tested the BFG Edition decensor patch on the Bethesda.net IWAD and confirmed it does not work as it bricks the game's IWAD file, preventing it from booting, even on DOS. Please test and confirm fixes are working properly before listing them.)

    "I’m on PC. Can I drop my own WAD files on the client to run them?
    Actually...yes! Browse to your installation directory and put any WAD files into your Saved Games\id Software\DOOM Classic\WADs folder (or the equivalent folder for DOOM II) and they will be recognized in the Add-ons menu. Note that only WADs compatible with so-called vanilla-DOOM and DOOM II will function at this time.

    Basically the first connected XInput controller is always connected and used by "player one", aka the one with the keyboard and mouse. There does not seem to be a way to disable this and allow the XInput controller to be used by "player two", so at least two XInput controllers are required, or a controller of another type (e.g. DualShock 4).
