After an "argument" in the launchbox discord, i did some googlefu and found out that dosbox daum has the option to mount zip files.
@Zombeaver promptly tested if it worked properly and surprisingly it does
So here is a guide on how to run zipped DOS-Games.
Download DOSBOX Daum from http://ykhwong.x-y.net
Unzip (DOSBOX Daum, not yourself)
Make 2 folders in the unpacked dosbox named "Data" and "Games"
Copy your Games in .ZIP format into the games folder
Start dosbox and type: "mount c Data:Games\YOURGAME.ZIP:/" replace YOURGAME.ZIP with your zipped game name, i'll use LBA.zip (little big adventure) here:
Start your game as usual:
Success
You'll have to keep your isos in a seperate folder if you have to mount them for games that need them (Daggerfall, Little Big Adventure, etc.) and there are probably a few other problems and glitches but so far it works pretty good.
