@edmaul69 Hi i am attempting somthing similar with a Super Nintendo reset button and am looking for a script that will exit the current game and go back the the game select screen.

Do you happen to know of a working one?

many thanks

You need to reverse that. Most fans are going to need 5v to run. You can also use the 3.3v pin (pin escapes me right now), to run fans quieter, but those are the pins to run fans on for the pi. Also recommended are heatsinks for all of the sensitive chips (including the one on the bottom of the board). Use pins 2 and 9 for the power switch but not recommended for corrupting the sd card. I got one of the push button switches that connect to the micro usb port in between the pi and the power supply. It will also clean up your power feed.

Yes, you need two ControlBlocks to support 4 players. The capability for stackable ControlBlocks was recently added.

@rablack97 I can make that work! I printed a panel for the HDMI, two USB-A, and a USB-B(power). I can cut the USB-B to micro USB (which is what is inside the arcade panel console), run a wire to that button(which I actually ordered yesterday), and then plug the other end into the pi.
