Hi guys.
I have a problem with thoose Naomi Game.

Back of the motherboard with the PSU plugged in and powered on. From the picture, it's CN1.

I don't know why but I had to run Royal Rumble at 5.15V to work, otherwise it boots to a black screen. Every other cart works fine at 5.00V.

Try giving it some more juice.
