ENDOOM captures[edit]

Hi Mightion, welcome to the wiki.

It's always good to see more documentation of period PC environments, and IMO it's even better that you actually read the article first to see what was missing.  :>   You should know, however, that other contributors have tried to remove compression artifacts from the screenshots.  This looks OK to me, but I'm not a DOS expert — if you still think your files are better, I recommend posting about it before someone deletes them.

Thanks again, and happy editing!    Ryan W (living fossil) 01:03, 30 July 2017 (CDT)

Nah, that's okay. I just saved them in .jpg format out of habit. I just got back into Doom-Heretic-etc about a week ago so I thought I'd share some stuff... I'll probably scan my Heretic and Ultimate Doom CDs later and add their images to the cover art section.
