This is a betatest! I did some installations myself and it seems to be working. Still: Do not expect everything to work.
Also I am not responsible for any problems with your system when testing this.
I made some alterations to my scripts.
So I kindly ask you to test them.
The best way to do so is to have an osmc install without RetrOSMC installed.
Now you only have to install the addon from zip. If you run it and do not have RetrOSMC installed, it should ask you if you want to do so.
Other changes are, that you can now access settings like CECFIX and HYPERIONFIX from the addonsettings and start the retrosmc installscript and the retropie setupscript from there.
Also you can setup scripts to run before and after emulationstation starts/quits.
You will need a connected gamepad or keyboard to navigate the menus though. Make sure they are recognised by Kodi by setting them up in the input menu.
You can also install this by traditionally download the script via ssh and run it from the home folder but I'd like to test the install from the addon.
Please get the addon from here:
Let me know if there are any problems.
You can check the new code on github:
Edit: If you want to update an existing installation, delete the old install-retrosmc.sh script from your home directory, download the install-retrosmc.sh script from here:
Make it executable:
chmod +x install-retrosmc.sh
and select "Update scripts" and "Install/update Launcher Addon"
