Was the Sonic 2 cart actually used during gameplay?

Yes. The S2K ROM in the S&K cart read level data from the Sonic 2 cart.

Sonic 2 is 1MB, the ROM I mentioned is 256KB. Take a guess.

I guess the biggest problem is Knuckles requiring a whole new set of sprites since the palette is different (this is the exact same problem Sonic 1 has as well). Also I think it just uses its own copy of the engine, in part to implement Knuckles' skills and in part because the original engine really wasn't made for extensibility like that. Also it adds some objects around where Knuckles can reach but Sonic couldn't, so I suppose it has its own object layouts (the same way it patches Sonic 3's), although not its own map layouts and such.
