Help with brutal doom (zdoom retropie 4.4 pi 3)

[8bitkid]

So i already installed zdoom and got it to run doom/hexen/strife etc no problems it even loaded the strife voices.wad and the hexdd.wad all fine but as soon as i try brutal doom it goes black then it just kicks me back out to emulationsation. id realy apreciate some help ass all evidence suggests this should work

my .sh is stored at /home/pi/RetroPie/roms/doom/Doom/Mods/Brutal Doom.sh

looks like this

#!/bin/bash
"/opt/retropie/supplementary/runcommand/runcommand.sh" 0 PORT brutaldoom

the emulators..cfg is stored at /opt/retropie/configs/ports/brutaldoom

looks like this

zdoom = "/opt/retropie/ports/zdoom/zdoom +set fullscreen 1 -iwad /home/pi/RetroPie/roms/doom/Doom/doom.wad -file /home/pi/RetroPie/roms/doom/Doom/Mods/brutalv20b.pk3"`
default="zdoom"

i have checked the file addresses of the .wad and .pk3 files they are perfect but it still wont start have i got something wrong in the emulators.cfg

for reference i have also tried adding my doom.wad and doom2.wad to this and still no luck perhaps 4.4 has no pk3 support??
