there's already an autoload feature, in your zdoom.ini file (zdoom-username.ini for nt users) there should be (if not you can add it) an autoload block for each gametype, here's mine for hexen and heretic:
Code: Select all
[Hexen.Autoload]
Path=HHDecals.wad
[Heretic.Autoload]
Path=HHDecals.wad
of course those wads will load every time you play the game. I think what you want is the magical invention called A LAUNCHER
