How to replicate the problem:

I have a micro (usb) arduino with two connected mega drive controls and two ps3 controls.
The arduino is permanently connected to the PI, it would have and have specific hotkeys for the core of the Mega drive.

Is it possible to define a control for each Core?

E.g. I set the arduino as the only control for the core of the mega drive and set its own hotkeys and PSX I set the PS3 control with its own hotkeys.

Plus: Possibility of defining multiple controls in a hotkey

E.g. Mega drive MODE button and PS3 HOME button are registered for the Enable HotKey function (this can happen if you can configure a keyboard key and a keyboard key, but it does not support 2 or more different controls.

With this it would be possible to configure the two mega drive controls for the two to open the retroarch.

This is more like a function request than a doubt, if this is already possible, how do I do it? if it is not possible, where can I request the implementation ??

I tried to be as clear as possible.

Thank you.
