Also check and see if the sound is working, you can use that to hear the Sega CD boot sound. If you are using an RF connection, use an AV cable, as the RF circuit tends to break or degrade.
The Genesis does play cartridges, but with the sega cd attached i notice a lot of interference and degeneration in signal compared to the genesis by itself. I have access to only one genesis and cd. When the bios starts, i can hear the music, but there the background of the moon for a split second, then it goes into this purple/blue haze static. I only have an RF adapter, my AV is coming Tuesday.
