I saw a Master System game called Dragon in a video called "Top 20 Co-Op Master System Games", but when I searched for it, I only found Dragon Crystal or Double Dragon in the results, but not this game. It looks like the video is the only proof that it exists. I think it might be false, but there's actual gameplay and I don't see any reason why they would do that (put it in the list).
The game itself is a fighting and platform game for the Sega Master System. Can anyone help me find it?
