I'm a bit confused with using ZDL and GZDoom. I downloaded GZDoom and BrutalHEretic, Brutal Hexen and BrutalDoom. When I start GZDoom with the Brutal Doom pkg it works fine. But the Heretic and Hexen files are in folders which GZDoom does not see. For example there are new Textures and sounds but those get not loaded in Heretic and Hexen.

Then I installed ZDL in the directory of GZDoom. I added all the wads and PKG s but then GZDoom crashes or I get an error that for ex. soundfx is loaded double or similar. I have made two pictures, maybe someone can explain me how to use this.
