Ports won't launch from Emulation Station

[LeonardChallis]

Pi Model or other hardware: Raspberry Pi 3B+
Power Supply used: Official charger from starter kit
RetroPie Version Used: 4.5.1
Built From: retropie-4.5.1-rpi2_rpi3.img.gz (from RetroPie.org.uk)
USB Devices connected: Logitech Keyboard/Mouse dongle
Controller used: PS3 Dual Shock
Error messages received: None
Log found in /dev/shm/runcommand.log (if relevant): https://pastebin.com/RQ59bWZm
Guide used: N/A
File: Presumably /home/pi/RetroPie/roms/ports/Desktop.sh and /home/pi/RetroPie/roms/ports/Kodi.sh
Emulator: Ports (Desktop and Kodi)
Attachment of config files: N/A
How to replicate the problem: Select Kodi or Desktop from the Ports section of the menu

This is an almost vanilla installation of RetroPie. What I've done so far is:

• Added some roms to other console folders
• Installed Pixel desktop via Configuration / Tools > Raspbiantools > Install Pixel Desktop Environment
• Installed Kodi via Manage Packages > Manage Optional packages > Kodi > Install from binary
• Added the following to es_systems.cfg because it didn't automatically do it when I installed the two above packages:

  <system>
    <name>ports</name>
    <fullname>Ports</fullname>
    <path>/home/pi/RetroPie/roms/ports</path>
    <extension>.sh .SH</extension>
    <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ psx %ROM%</command>
    <platform>ports</platform>
    <theme>ports</theme>
  </system>

When I try run either the Desktop or Kodi option from the EmulationStation menu, after a few seconds it just drops back to the menu. No error is shown in this interface.

I also read that there is a Kodi error file in the home directory but I don't see one of those available.

Thanks in advance for any advice.

@LeonardChallis
First of all it looks like your es_systems.cfg isn't configured correctly.

There's a couple locations for es_systems.cfg
https://retropie.org.uk/docs/EmulationStation/#editing-es-configs

The original location which is re-written everytime you update RetroPie and install new emulators:
/etc/emulationstation/es_systems.cfg

And your custom one that overrides the original if it excites and is not automatically re-written by RetroPie:
~/.emulationstation/es_systems.cfg (which is a symlink to /opt/retropie/configs/all/emulationstation/es_systems.cfg)

You could look for Kodi and Desktop configuration in /etc/emulationstation/es_systems.cfg and manually add those changes to ~/.emulationstation/es_systems.cfg

Note: I'm not at my RetroPie to look to see what the correct settings should be.

Okay, here's what I've got in es_systems.cfg

  <system>
    <name>ports</name>
    <fullname>Ports</fullname>
    <path>/home/pi/RetroPie/roms/ports</path>
    <extension>.sh .SH</extension>
    <command>bash %ROM%</command>
    <platform>pc</platform>
    <theme>ports</theme>
  </system>

And then put this in/home/pi/RetroPie/roms/ports/Kodi.sh

#!/bin/bash
"/opt/retropie/supplementary/runcommand/runcommand.sh" 0 _PORT_ "kodi" ""
