Anyone ever played a Neo machine that has 2 screens?

I was meaning to post this awhile ago. Before I really even started collecting Neo stuff, I was down the shore and there was a Metal Slug arcade machine (not even sure which metal slug it was now...) But it was obviously a 1-slot, but the thing is, up by the marquee, there was another, really small monitor, that was extremely sharp and clear. It was extremely cool. Anyone seen one of these?

It sounds like a conversion from a hyper 64 to a mvs. I believe the hyerper 64 ded cabs had the small screen on top. <IMG SRC="smilies/spock.gif" border="0">

I've play one before. It's cool. If you link 2 up, it shows a video of the two players playing each other.

Never heard of it, but it sound pretty sweet! <IMG SRC="smilies/glee.gif" border="0">
