So - looking to buy some wireless controllers and a 'dongle' for the XU4, specifically for the setup. I'm thinking about 4, so the more value the better!
I'm thinking PS3 wirelss controllers, as you could use the PS button as the Hotkey? Is the XU4/Batocera compatible with these? If not - any recommendations?
As an aside - what would be really great would be the option to change the 'help' button icons on Emu Station from the default "A" "B" etc to match the controller you're using (e.g. with PS controllers use Cross and Circle etc). Couldn't you just swap out some image files somewhere? Would that be possible in Batocera?
