I have it working on my Maverick laptop, with a Quadra 950 ROM, 7.5.3 128MB RAM (I put it together last night, after I saw this thread) - the only issue that I have is that it will sadmac/freeze when I restart it.  If I shut it down and start it, it runs fine.  Actually a lot more stable than the sheep shaver that I have on my MacPro.  If I could just find my games folder...

I agree with Elfen about the resolution, I didn't use their suggested resolution and started with 600x800 instead.

I specified a system for "any' macintosh in the installer and removed the stuff that I didn't need.
