morhlis: Its a shame - Haven't seen McTecman post in here in quite some time. But I'm sure he's busy. Maybe we'll see him on here after awhile. 
    Testing out various installer packages. Getting them to install something is very easy, getting them to prompt for the user to point to a folder with existing files, copy certain ones from that folder a dozen times, THEN resume the install is turning out to be a nightmare. I know it's doable in some scripting solutions, but it's not easy to learn that from nothing. 
 dudalb - Yeah, pretty much. Hell, if you don't plan on playing the mods, you can pretty much delete all of the folders within /Games/ except Blood, CDMount, GZDoom-Blood and zmbv (or Video Codec if you've upgraded to Dosbox 7.4. If you don't care about cutscenes you can also nuke game.gog in CDMount (if you've followed the instructions, it should be just there). All the Launcher will do when you attempt to run them is boot up Dosbox, and it'll just close when the files don't exist. 
 I'm not sure how the hell to make the music play with a single map (custom or official), since .ini files dictate which track plays when. Okay, that's partially a lie - .def files also enable music to play for custom levels. Still looking into it. A partial solution would be to load a dummy file with a randomly selected music track, but I need to a) test if this works for official maps and b) see how level transitions work when you beat the selected level. 
 tl;dr: Derp.
