Master System Light Gun to Genesis

[ussexplorer]

I'm so sorry and I swore I have found it before. I have two phaser light guns and I want to play corps killer. I have a blue gun for the genesis but as you know it will not work. So I plug the phaser light gun into corps killer and it detects. But I can't get it to fire. I assume it needs to be re-pinned. Anybody can point me to a howto or something I would appricate it.

 

Thank You,
