Old thread... My first thread.
I answered some question on myself.
I know I can create maybe "DOOM-TNT.sh" and can put command from emulator call from DOOM.WAD to TNT.WAD. But now if I save games from DOOM1 and DOOM-TNT they are all displayed in both games titles togehther. This is a bad solution.
I created some bash scripts that will solve that.
You now need only one folder with all WADs inside.
You will need zip support enabled so please get zip with sudo apt install zip
Get the scripts here from github
Update: 15.07.17
added FreeDoom1
added FreeDoom2
They work flawless!
Quake issues ...
Two ways...
Use the wiki
here! It's the recommended way
If you lack of space or you are not able to run Quake and it's official and inofficial packs you can
discuss here
Maybe next year I'm back with HeXen and Heretic :)
