Hello,
When I was on older version of batocera (5.11 I think) I was able to access to dolphin conf with command line on ssh:
export XDG_CONFIG_HOME=/recalbox/share/system/configs
export XDG_DATA_HOME=/recalbox/share/saves
export DISPLAY=:0.0
dolphin-emu
But with 5.25 it don't work anymore, the message is "mit-magic-cookie-1 key could not open display"
Thanks for your help.
