Adding new system x86

[WhiteT982]

Pi Model or other hardware: i7 7500T Ubuntu 22.04 x86

RetroPie Version Used: 4.8.2

Built From: Setup script download 
Emulator: Xemu

Downloaded Xemu through flatpak and am able to launch a game with it through command line using.

flatpak run app.xemu.xemu -dvd_path “gamename.iso”

To launch through ES I made a /home/pi/RetroPie/roms/xbox folder and added roms to it. Then I copied the es_systems.cfg from /etc/emulationstation to /opt/retropie/configs/all/emulationstation and added this Xbox system config

<system>
    <name>xbox</name>
    <fullname>XBOX</fullname>
    <path>/home/pi/RetroPie/roms/xbox</path>
    <extension>.iso</extension> 
<command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ xbox %ROM%</command>
    <platform>xbox</platform>
    <theme>xbox</theme>
  </system>

Next I made a /opt/retropie/configs/xbox folder and added this emulator.cfg

xbox = "flatpak run app.xemu.xemu -dvd_path %ROM%"
default = "xemu"

System shows in ES with roms but won’t launch.

I can change the es_system.cfg to launch scripts by adding the .sh extension and changing the command to just %ROM% and games will launch in ES using this script

#!/bin/bash
flatpak run app.xemu.xemu -dvd_path “gamename.iso”

Any ideas to get this to work without writing scripts for each rom? Only thing I could think of is it won’t launch a game without the rom being quoted. I tried quoting the %ROM% from the command line in the es_system.cfg but that didn’t work. I guess I could rename the roms to have no spaces or other characters but just hoping for something simpler.

default = "xemu"

Try :

xbox = "flatpak run app.xemu.xemu -dvd_path %ROM%"
default = "xbox"

@Folly
Ok I will. I thought that line just told ES the default emulator? I’m curious if otherwise because this is mostly me copy/pasting so I definitely don’t fully understand how all this works

@WhiteT982

You can also remove the default line.
When you select a game it will ask how you want to load and then it will be added in the emulators.cfg.

@Folly
Alright I’ll try next chance I get.
