Well that should be good news then, right? It sounds like the DC version was better than the arcade version. From one person in the comments section:

"Anyway, I worked in a Babbage's in a mall when the Dreamcast launched. I had never heard of the game but I saw tons of it when the demo units came in, bought it and a Dreamcast, etc.

Then one day the dink-ass arcade we had in that mall got an arcade version. Man, I had always heard the Dreamcast version was better but I didn't know by how much until then. The Wikipedia article doesn't mention what exact hardware the arcade version ran on but I seem to recall hearing it was PlayStation 1 hardware essentially. It would make sense. If nothing else the resolution on it was pretty low."

I don't really remember how the arcade one was since it was such a long time ago, but I thought the DC one was pretty damn good :) Sounds like good stuff:D

 the arcade was on the system 12, which is basically a souped up playsatation, i.e. more ram, faster processor ecetera 

regardless the dreamcast release is much much prettier
