So the 7800 just arrived and I haven't been able to figure out how to hook it up. It came with a set of cables that only have one prong on each side, I guess it's too old for my blood because I was expecting either an RFU hookup or a/v composite cables at best. Is it possible to use these one prong cables with a "splitter" that lets you use multiple consoles with the red/white/yellow three pronged cables like the one I have plugged into my TV, or do I have to find another method?
