Game Input MultipleXer

I hope to understand something! for now thank you very much for your availability!

okey i try to read how to do it, do you know if someone already has a hex mouse to mouse firmware? It would save me a lot of time ... if it doesn't exist I will try to find out how to create it myself, if I can create it I will post it here, maybe it is useful to others ... Thanks for the informatio...

if there is a need I also have other more performing arduinos ... in case you can advise me what I need? however, is it possible to emulate just the mouse? is there already hex firmware that i can install to try? or a guide on how to get a firmware that makes me mouse to mouse? I saw it exists only ...

Hi, I wanted to know if finally there is a way to emulate KM to KM? I already own the gimx purchased years ago on the site ...

thank you in advance for any reply...
