Corpse Killer Sega CD controller option

i was wondering if their is or will there be an option for controllers. it seems that this and one other sega cd game will not work if their is a second controller input. you can play the game with a second controller, but you can’t move the cursor unless you use the first controllers analog stick. you would need to set the second controller port to empty in order to play this game.

I have a similar problem. I’ve tried getting this rom from several places and they all work the same. On the android RetroArch, I can move the cursor to select a mode on the title screen but no other buttons work, even using the overlay.

On the PC version of RetroArch, I can’t get anything to control. It’s as if there is no controller connected. Has anyone had any luck or have any ideas as to what to do with this game?
