I was playing my copy of Sonic 2 (i dumped it myself), and noticed that CPZ has a different color palette on the background, than the ROM I have on my emulator from a previous download. (before I dumped my own cartridge).
I will get a screenshot in a moment, but, was their different revisions of Sonic 2?
EDIT: Turns out the emulator I was using (Genesis Plus) on OS X loads the palette incorrectly. I used two emulators side by side, so my bad.
I can't believe that guy charges for his emulator, and they aren't even good. Pitty to anyone who actually buys the full version. (It's YM2612 emulation is horrible)
Not that it has anything to do with the pallet issue you saw with that particular emulator, but S&K checks for three different revisions of S2, and two of them are dumped.
Rev 00 - First revision, dumped, minor bugs present (CNZ1 signpost few pixels too low, typo in credits)
Rev 01 - Second revision, dumped, some bugs from rev 00 fixed ("Super Sonic transformation-after-endpost" bug still present)
Rev 02 - Third revision, undumped, known to exist because S&K checks for it, could potentially be the build that exists in Sonic Classics/Sonic Compilation (with fixed "Super Sonic transformation-after-endpost" bug)
Rev 01 is the most common version in the wild, I'd hazard a guess that it's most likely what you have. If your cart's header shows 02 then please share the dump with the Sonic scene, so that we can have a complete series of unmodified retail S2 dumps.

The best part is when an emulator of his has had bugs for years, and he still expects you to upgrade to the paid version. (which just enables features, so the bugs will still be there) The ColecoVision version doesn't emulate the right fire button, plus it aborts on any access to an undefined memory address. I think there was also some other bug I found in it a couple of years ago, but I don't remember it any more.
I contacted him about the bug, and I get pointed to Generator, which doesn't have the VDP bugs, but instead like Genesis Plus, still has shitty audio, which he blames my Macs sound card, which is bogus. The spinner at the level of an audio shouldn't sound so distorted...
Thing is, I like using Genesis Plus because it has the NTSC filter. So, I have two different emulators from the same guy, and they both want things I want in the SAME emulator.
I currently use picodrive for the PSP for my Genesis/CD emulation. It's the finest SEGA emu on the PSP at the moment, even playing things like Sonic CD and EWJ:SE at full speed.
