Please help! Dolphin crashing when playing Sonic!

[acer1096xxx]

Hello, I recently downloaded Dolphin for my Mac OS X Lion and it works great. One problem I noticed was when playing Sonic Adventure Battle 2, the game eventually crashes dolphin. If I disable dual core, then the game will stop crashing, however, it will run too slow.

So what can I do? Enabling dual core makes it fast but crashes it, and disabling dual core makes it slow but doesn't crash it.

Thanks.

I apologize for my impatience, but does anyone know how I may be able to run the game faster without it crashing?
