Q: I am making an arcade table with Raspberry & Retropie Software..
I'm no expert.. I need your help to buy a Keyboard Encoder compatible with my install. What do you recommend?
A: We offer the Ultimarc I-PAC-2 2 Player USB Pushbutton and Joystick Interface PCB https://www.focusattack.com/ultimarc-i-pac-2-2-player-usb-pushbutton-and-joystick-interface-pcb/
I've linked a recent project done by a RetroPie user as well: http://www.iliketomakestuff.com/raspberry-pi-arcade-part-1/
See our product details on the link, as this encoder covers so many keyboard features.
