In case anyone's interested, BizHawk 1.7.0 was released today. (Same day as Windows this time)

Some highlights from this release:
- Adds a new NES core, QuickNES, which is faster than the previous NES core but less compatible. Both cores are manually selectable, but the emulator automatically detects the mapper of the game you open and picks QuickNES if it knows the game will work. Even though the existing NES core ran full speed already, this new one is about twice as fast so if you're doing something that requires you to be able to run a NES game at over 200fps, I guess that's good.
- Adds support for the Wonderswan and Wonderswan color systems, in sync with Windows 1.7.0
- Adds support for Gameboy, Gameboy Color. Windows has had these for awhile now, but they're finally supported in the OSX version.
In summary, the following systems are currently supported on the OS X port:
NES, Famicom Disk System, Sega Master System, Game Gear, PC Engine/TurboGrafix16, Atari 2600, Atari 7800, ColecoVision, Genesis/MegaDrive, Sega CD, Gameboy, Gameboy Color, Wonderswan, Wonderswan Color.
That leaves only a few systems that the Windows version supports but not OS X. I hope to close the gap further in future releases.
Edit: Version 1.7.1 is out:

Although there are changes, I'm not sure if any are notable. Mostly bug fixes.
