Bought myself a broken NES, removed the old hardware. Picked up a rpi 2 and ATXRaspi for a clean shutdown for de Pi, works perfect! Re-used the buttons from the NES. Got a nice blue Power LED. I got rid off the controller inputs and replaced it with USB. The NES now comes with a HDMI ouput and UTP for transferring ROMs.
Used retropie software 3.0 BETA 2 for rpi 2.
With much help of this blog it starts up in a nice clean (no logo!) random splashscreen from sur0x. Used the scraper from sselph, with good results! It runs perfect!
