After hours of searching for the answer and not finding a definitive one, I must ask you: how do I have to setup Doom Builder 2 in order to get my own map load in Doomsday Engine when clicking the "Test map" button in the editor? I have tried all sorts of parameters in DB2's "Game Configurations > Testing" -tab on nothing seems to work. I always end up in DE's game selection window, and if I then select the game my map is based on (let's say Doom 2), it only loads the original map and not the one I was working on.
Currently the only way I know how to get my map boot up in Doomsday is to copy-and-paste my WAD-file into the Addons-folder that lies inside the Doomsday/snowberry-folder. The problem with this method is of course that it is way too slow and cumbersome.
Any help help would be highly appreciated, thanks!
