Adding PS2 support to Qanba Q4

I need to add PS2 support for my Q4. I’m thinking of wiring a MC Cthulhu to the buttons and have a separate RJ45 for that. So I have 360/PS3 by default, and when I need to I can connect to the MC for other consoles. Would this work?

I mean, I want to share the buttons for both PCBs. Is this possible?

Power to Power line, Ground to Ground. :stuck_out_tongue:
Of course!
