Bah, Genesis emulators are I think an area where we really need something: a) Highly portable b) Focused on accuracy c) Under a fully open source license We've got all three for the NES (Nestopia), Game Boy (Gambatte), and SNES (bsnes) now. But the Genesis is rather overlooked. Kega Fusion is accurate, but closed source and extremely Windows-specific (I think SteveSnake is beginning to regret coding 99% of it in x86 ASM now that x64 is taking over the world). Gens is pretty accurate and reasonably portable, but actually under conflicting licenses (it claims to be GPL, but the Starscream 68000 core is under a non-commercial use license only). Regen is highly accurate and portable, but also closed source (disappointingly, I was hoping for it be the One True Emulator), and it doesn't seem to do SegaCD or 32X either.
All others are less accurate, discontinued, and mostly closed source. As for SegaCD on Mac OS X, MacGens does seem to be dead (somewhat appropriately, given Reaperman's suggestion, because the author stopped using Mac OS X it seems). So I'll assume you're on an Intel Mac, in which case the best solution would seem to be to use Kega Fusion with good old Wine. Usually on a Mac this would mean Darwine, but that has died since I last checked on it, and now it seems is the new way of using Wine on Mac OS X. If you're not using an Intel Mac or Kega Fusion won't work using WineBottler, then you're shit out of luck as far as I know.
