Eightman should exist somewhere on cd sice many places I know said they sold it in the past. and I hope Kizuna Encounter Super Tag Battle came out on cd also...if not then there are a grand total of 99 games on the cd system, if Kizuna IS on cd then the cd system has a total of 100 cd games!
I think I have Kizuna Encounter NGCD, but I'd have to check, and that stuff is in storage at the moment.
Basically, I got my NGCD with several games in a trade, and I remember there being one fighting game that wasn't one I remember playing and wasn't really interested in. The phrase "Super Tag Battle" definitely sounds familiar...
It will be several months before I can get at that stuff again (it's in Colorado, I'm in Kentucky), unfortunately.
