So yeah. I noticed that the middle Lightkey button wasn’t working when I tried using it as the screenshot key in Retroarch. The LEDs all light up no problem, it’s just that the key does nothing.  
I looked at the raw events with `showkey` over SSH and the key straight up does nothing, even there. All the other keys send keycodes.  
How do I rebind the keys in order to get this working?

middle key is a clone of the shift key, to change it you need patch the keypad firmware

> Is it possible to bind the useless LightKey middle button to Pause Game in retroarch? I tried binding it in Retroarch directly but it seems that I can’t bind anything in there, this must be another GREAT effect of this OS v.04… So, in retroarch.cfg, how can I achieve that exactly. Thanks

Oh, I didn’t know the keypad actually ran arduino stuff. That’s so neat!  
Thanks for clearing things up.

i could also recommend you to use the emulated mouse firmware \>
