I played Final Fight CD (Japanese version) on Kega Fusion. It's neat how near arcade perfect port this was for the time. The soundtrack is awesome, and the Japanese got the better deal compared to those in the West. The Western releases are still good, but suffer from painfully bad and dull voice acting, a less bad ass intro, slight censorship, and some small details only the Japanese version has. With that said, the gameplay is virtually unchanged and keeps all of the gameplay quirks no matter the region difference. FFCD does slightly worse hit detection and becomes noticeable when adding the rapid-fire button cheat. Can't wait for the SG Mini 2, so I can at least play it on the big screen.
