Actually, this could be a great re-opening of an existing function, adding a second layer of almost “gesture” like inputs.
In another thread recently, re: mapping a player 2 for the gameshell, @Petrakis brought up that it should be viable to have a secondary mapping of the dpad+shift.
That would be doing something based on an arduino being flashed. However a software solution could be doable. I have done some similar things with xbindinput, just for some quick shortcuts to terminate programs. Something could be done, scripting mould gestures.
On another note, I don’t see how replying to a post 10 months later with something that is not constructive, and seemingly demeaning to the original topic has any purpose in a forum such as this. I think you hit the nail on the head @adcockm. We are about going forwards and innovating.
The second reply is doing the exact opposite.
