any plans to remove the carbon dependencies?
Long answer: Advanced Mac Substitute is factored into back end (the emulator itself) and front end (graphics and user input terminal). Writing a new front end from scratch is actually not that much work, and the OS X front end is due for a full rewrite anyway.
This would be an excellent opportunity to contribute that doesn't require any 68K or classic Mac knowledge.
But I dropped a link with a friend of mine who is super into classic mac, and mac in general.
In the meantime, you could run the Linux framebuffer front end, which, strictly speaking, doesn't have Carbon dependencies. :-D
