Hi there, did everything according to the instructions. Testing works while i run retro game. However after i restart the buttons don't work anymore unless i start retro game. there seems to be a problem with automatically running retro game on system boot ? I put this line /home/pi/Adafruit-Retroga...

Running a second wire from the PWR Usb Pad alongside the HDMI cable will also work, won't it?
In case i don't want to use a Voltage inserter/HDMI USB Adapter
