You don't, you go into the options and choose that EXE for "Test Map". Or, you could set it up to show said dialog EVERY time you test the map - I do, considering I use DB for both SRB2 and whatever DOOM variant I decide to download some odd day (usually ZDOOM-related).Roboashura said:How do I change the DB config to use that rather than srb2win? Or start a new one, whatever works.
