Difficult to say, but from memory your average shmup on a lo-res screen moves at around 3 or 4px/frame. I'd imagine something like Superfrog would push 8px/frame and like I said, the SMS version of Sonic is doing 8px/frame.

But of course it depends on the resolution too I guess

Load up an emulator that supports single frame skipping (or maybe a max speed in % setting) and you can take a look yourself. You might be surprised how slow it's moving, but the multiple layers of parallax give the impression of speed.

I seem to remember Chemical Plant Zone (Act 2) on Sonic 2 on the Megadrive was like that. The first part where you run down that huge ramp and through a ton of loops. The parallax scrolling gives you the impression of massive speed, and then of course Sonic disappearing off the screen makes your brain think the character's going even faster.

Cool stuff, is scrolling
