I recently went out and bought a new surge protector. It is a major improvement because it allows me to hook up my tower of power (3 brick AC adapters), saturn, dreamcast, Xbox, 360, TV, Audio Receiver, and Audio mixer. It's nice not having to unplug everything to play the SEGA CD.
I also finally bought a Audio extension so I can connect the composite audio to the receiver and not the TV.
Next on my list is to buy some SCART (RGB) cables for the Genesis and Saturn along with a SCART to component converter to connect to US televisions. Then the VGA cables for the Dreamcast with a VGA to HDMI or component converter. Then, I should have my setup the way I want.
