It's hard to convey how absolutely transformational it was for me to play Space Harrier in an arcade back in the day. The graphics were mind-blowing. Big part of why I became a programmer, even though I went down a different path than game development. Those big, bright, detailed sprites moving around with hardware-accelerated scaling at a smooth rock-solid 60fps! There had been nothing like that before. I mean, we'd…
Makes me realize how MAME is insufficient to reproduce the incredible gameplay of Space Harrier (I don't say this as a critic of Mame but more to express that there was somethign really special about Space Harrier). The moving cabinet was so smooth and the joystick reacted so well to the manoeuver (especially when you had to do that "triangle" to avoid the mech at the higher levels). Anybody remember the Asute level…
Playing a game on a modern platform (including MAME running on a PC) adds about 100ms of latency, minimum. That's not a ton of latency, and games can still be plenty fun, but it's on the threshold of being noticeable and even if we're not conscious of that input lag, it's just not the game as that "I'm wired directly into the machine" feeling of a true zero latency setup.

(of course, even in an all-analog setup, there can be latency, but not on the order of 100ms. at least not on the hardware side of things)
