1) download the file libretro_xxx.so for rpiX
2) connect to the batocera via ssh
3) mount -o remount,rw /
4) copy the .so file to /usr/lib/libretro
5) edit /recalbox/share_init/system/.emulationstation/es_systems.cfg, nintendo ds section to add this file as a libretro core
6) run /recalbox/scripts/recalbox-save-overlay.sh
7) reboot
Does not work with Batocera 5.8. The core is automatically deleted when restarting and this line does not work /recalbox/scripts/recalbox-save-overlay.sh
Error in line 20
The correct destination is /recalbox/share/system/.emulationstation/es_systems.cfg
(File es_systems.cfg is missing. Therefore it is to manually add) and not /recalbox/share_init/system/.emulationstation/es_systems.cfg
