Play Muhammad Ali Heavyweight Boxing (Proto) Online
Dodging punches feels heavy and deliberate—Ali’s footwork actually looks real, and landing a clean combo makes the screen shudder like you just rocked someone. That awkward block button’s worth learning when you start slipping jabs and firing back with stinging counters.

Game Overview
Man, stumbling onto Muhammad Ali Heavyweight Boxing (Proto) for SNES feels like digging up a lost treasure. The moment you start a match, you notice how weirdly smooth the animations are for a '90s boxing game—Ali’s shuffle actually looks like Ali’s shuffle, and when you land a clean right hook, the screen shakes just enough to make it feel brutal.
It’s got that arcadey Punch-Out!! energy but with more weight behind the punches. The controls take a round or two to click (why does blocking feel so awkward at first?), but once you get the rhythm down, bobbing under swings and countering with a lightning-fast jab feels amazing. And yeah, you’ll absolutely try—and fail—to mimic Ali’s taunts between rounds.
Shame it never got a proper release, because this prototype’s got more personality than half the finished sports games from that era. If you’re into retro oddities, this one’s worth a few rounds in the ring.
