Sega CD games wont "play"?

[retrojules]

Whenever I try to play a SEGA CD game it boots to the US Screen (as im using the us bios) and it says "press start to play". When I press start, it just goes to the CD music player CD+G program screen. Nothing works to get it play the game! I've tried multiple games. I've tried my keyboard and my gamepad. Nothing works! I know the images are fine because it works fine in retropi and on retroarch on my PC.   Help me out here please!
