I sure hope I'm not the first to notice this lol, but I was playing Lunar on Sega CD today and I got to a point where I saw something that I just know HAS to be an X68000 Pro system. While my picture isn't very good, all the details are there when you see it on screen. The mouse/keyboard port are where they should be, the power switch is there. I love it when they put little easter eggs like this in games. I just wonder how many people outside of Japan might have recognized this back when this game was new.
Judge for yourselves:

Also in the same place in the game was a Mega Drive:
