OK, thx Milhouse
I'll wait for a fix. Hopefully, we will get one.

I think this is likely to be your fix:

Edit /storage/.kodi/addons/emulator.tools.retroarch/bin/retroarch.sh and change

Code:

nohup /storage/.kodi/addons/emulator.tools.retroarch/bin/retroarch.start "$@" > /storage/.kodi/userdata/addon_data/emulator.tools.retroarch/config/nohup.out &

to

Code:

systemd-run /storage/.kodi/addons/emulator.tools.retroarch/bin/retroarch.start "$@"

and Retroarch should now work without any changes to kodi.service.
