MarioDoom.pk3 is an awesome mod created by Valigarmander. Unfortunately, it only runs in Zandronum and GZDoom in it's current state, so I've done some minor tweaking to get a vanilla version made!   Download the vanilla version HERE: https://doomshack.org/uploads/MARIO_V.ZIP   Since it is vanilla compatible, it will run with any port. The .DEH file only seems to partially work in vanilla/choco, but it's purely for changing item pickup messages so it's not a big deal either wa
