Just bought a Sega Naomi setup with a Capcom IO for my Supergun. Plugged in all of the needed components and plugged the harness into the IO. The Naomi turns on and sounds like a jet engine, which means it's getting power, but no signal comes in. In some cases, it attempts to make a signal, but the TV acts as if there is nothing. I've flicked between the dip switch settings for 15K and 31K and used my VGA monitor but no results. I have a multi-region bios, but currently no cartridge (Akatsuki Blitzkampf, but it's on loan). Am I doing something wrong or is it messed up?
I love all video games.
