I primarily use Bootcamp due to the better emulators, but when I need to go back, I use KiGB. Unfortunately, to my knowledge, there is no link cable support or clock support. I used to use VBA, but that seems to crash a lot with my GBC ROMs. If anyone could point me to a better emulator too, that'd be splendid, but for what it is, it does its job fine. It runs nearly all GB/C ROMs at a good FPS. Only problem is the link cable...Oh well.
