No because I have a whole host of WADs and PKGs running at once. Visor mod, Brutal DooM, DooM Metal, a ZDL file holds a configuration of all these WADs, I'd like to boot up entire mod configurations if possible, but if it's not I'd understand and stick to firing up DooM through the launcher the old fashioned way. I just thought maybe someone knew a special command line or something that would make it launch the ZDL file through the launcher with BigBox.
