F-Zero GX: Game constantly resets if dual core is checked but can't run with one core

[Metal Man]

So I'm trying to run F-Zero GX on my macbook, and the game runs find in dual core mode, but randomly resets, which is highly annoying. I checked the wiki, which told me to uncheck dual core, which fixed it, but makes the game run at unplayable framerates. Is there anything I should do to make it run with stability?

Run your CPU hotter than 1.8Ghz, you can't possibly expect to run a game like that w/ one core at that speed.

The OP probably has an Ultra-Low Voltage (ULV) CPU.
Metal Man what is the exact model of your CPU?
