DrPengin Posted August 13, 2017 I know there are already topics on how to install Aliens TC, but this is different. I have a registered copy of "The Ultimate DOOM" and Dosbox as well (I know of source ports, but I would like help based on running it vanilla) as the "u_alntc1.zip" and "u_alntc2.zip" files extracted into my Doom directory. So I run the INSTALL.BAT file in Dosbox and it pops up with a message prompting me to specify which version of Doom i've got. For me I would type "INSTALL 1" as prompted, but it doesn't work. How do I correctly use the INSTALL.BAT file provided? Thanks. 0 Share this post Link to post
