When my kid presses L2 in pcengine emulation than we got this notice “6-button mode selected” and until L2 is pressed again playing is not possible. It would be great to know how to disable that uniq “feature”.
This is related to both pcengine libretro cores.
while in game press hotkey + start, then go to controls, port 1 controls and set L2 to none
One more question: is it possible to do it in batocera.conf (I mean once for all games)?
no, but you can save it within retroarch quick settings (i think it is called “save core override” or something like that)
Yes, I did that this way. I works like a charm.
