Did you play any of these? I bought a bunch ($9.99 - $14.99 a pop!) about ten years ago. They were available on RealArcade. Sonic, Comix Zone, Vectorman, etc.
The emulation was quite good! I feel nostalgic using this specific emulator. There was even an "Enhanced Sound" option that modified some operator to smooth out Sonic's jump sound.
I used to be able to redownload activated versions from my account page. They've discontinued support, but my page says I can still redownload them. Doesn't work.

I had a deal with Sega a long time ago, they used Gens sources for their Real Arcade emulator. I think they were quite disapointed when they received sources "Oooh my god, what a piece of crap ! How do this think can actually work !". Myself sometime i'm wondering ^^
