I tried to make famec, as used by UAE4All2, 64bit compatible. At least as long as emulated memory is located in the lower 32bits it might work.
I have zero knowledge about 68k emulation details. Maybe someone with more experience could look over my commit and tell me if this is an ok approach, or if it will never work this way?
Here is my commit:

I simply tried to elevate all pointers to 64bit, and make sure all the other uae* types have the correct widths.
Something in my gut tells me that this will never work. But I don't know why?
If it will never work this way, I'd rather not waste more time on it.
