Re: I shouldn't have worded that the way I did
There was a 6-button controller for Genesis later on. It looks like the MK games and SFII-CE used it. From what I remember about using the regular pad (don't feel like looking it up) you had to hold the punch/kick button for a certain interval to unleash the high or low move.
Magazines were getting lukewarm on MK by the third one. I always thought the MKII Shang Tsung looked more badass than the Alice Cooper dude.
