The CPS Changer was only released in Japan, and not many games were released for it. The system was basically Capcom's answer to SNK's Neo Geo system -the system was practically the same as their CPS-1 board, so the games you could get for it were the exact same as in the arcades. However, the CPS Changer was only available to order from Capcom Japan direct and it quickly flopped, although it has become a collector's item since.
Anyway, the reason this page exists is because I've read at several sites that a CPS Changer version of Champion Edition was released, but I can't find any concrete evidence that it was. Hyper Fighting definitely did get released on the CPS Changer, but does anyone know if Champion Edition did? I've a feeling it wasn't, but if anyone knows for sure, please get in touch.
