Just got a Japan Dreamcast, put it into a new shell and put in a DreamPSU, pluged it all back together, and I am getting these static type artifacts all over the screen though a VGA cable (first time I've turned it on). Checked all the connections inside they all seem fine.
Tried it though a scaler and straight into a projector, makes no difference. Is this caused by the VGA cable or something else?
