Literally just arrived. Plugged it into my 1C (which boots official carts just fine), It shows a garbled screen for a few seconds then boots to a dim grey frame that resembles the menu then a grey-bordered popup appears. There is no text anywhere. No indication of what's wrong. I was reading some similar threads and the only thing I found similar was a weak power supply but mine is rated at +5V@5.5A, +12V@2.5A, -5V@500mA which looks like it should be enough. WTF is going on?
