ZDoom Multiplayer

[DanMcCoy]

Hello

I have successfully managed to install zdoom in RetroPie on my Pi3 and it works just fine.
What I'd like to do is play a multiplayer network game.

the ZDoom wiki suggest that "multiplayer games must be started either from the command line or from a launcher of some sort".
https://zdoom.org/wiki/Multiplayer#Technical_details

I've tried creating a second menu item by creating a second ".sh" file in /home/pi/RetroPie/roms/ports

I've tried a few different contents for this file. I've tried:
#!/bin/bash
"/opt/retropie/supplementary/runcommand/runcommand.sh" 0 PORT "doom -join 192.168.0.xxx" ""

And also...
#!/bin/bash
"/opt/retropie/supplementary/runcommand/runcommand.sh" 0 PORT "doom" "-join 192.168.0.xxx"

But launching either of these from retropie produces the follwing message:

No config found for system doom -join 192.168.0.xxx

Obviously I'm going about this the wrong way. Can somebody nudge me in the right direction please? Or tell me if it's even possible?

Thanks

I run it directly via scripts:
(Host Coop)
#!/bin/bash
/opt/retropie/ports/zdoom/zdoom +set fullscreen 1 -host 2 -warp 01 -skill 2 -iwad /home/pi/RetroPie/roms/ports/doom/doom2.wad -file /home/pi/RetroPie/roms/ports/doom/mod.pk3
or
(Host Deathmatch)
#!/bin/bash
/opt/retropie/ports/zdoom/zdoom +set fullscreen 1 -host 2 -deathmatch......

or
(join)
#!/bin/bash
/opt/retropie/ports/zdoom/zdoom +set fullscreen 1 -iwad /home/pi/RetroPie/roms/ports/doom/doom2.wad -file /home/pi/RetroPie/roms/ports/doom/mod.pk3 -join 192.168.X.X

OR
Check out the Retropie Doom wiki, regarding mods. You could use the same commands above, but put it in /opt/retropie/configs/port/modname/emulators.cfg (that's what the "runcommand .sh " 0 Port" doom" stuff is pointing to...the "doom" directory in /opt/.../configs)
