ZDoom

I updated all of the mods but I'm not a big fan of the audio changes. Deleting the sound folder in SmoothDoom_SE.pk3 made the Chaingun sound go mute. Is there any way to properly remove the new sounds? Can I use the regular SmoothDoom.pk3 ?

I was looking for an updated version of Smooth Doom, since it became my favorite mod. I found the motherlode instead. Everything here looks incredible when bundled together, really nice job.
One question: how do I use this double HUD that I'm seeing in the screenshots?
