1.54 is up with a new screenshot.
I scrapped the previous file and started over with a fresh copy of Alien's original mod, so any 16x10 experimenting I did won't be present in this version. Also, I forced my monitor to 1920x1080, so I could confirm that everything is as it should be before packaging it up for download. Shorter: hopefully, no more bugs.
While I was digging around, I noticed that a lot of the math was off in some of settings. Unfortunately, I don't think it's something that little tweaks will resolve, but neither it is resulting in anything that makes this unusable. I may rebuild this from scratch at some point, but it won't be until after the 16x10 version is finished.
