You've gotta wonder what is going on. NatAmi is supposed to be a 68k Amiga clone with extensions. They have an open source program already written in the form of WinUAE and rather than taking it, adding SuperAGA functions and producing something for the community they write their own simulator which is not Amiga compatible??
Something smells fishy!
Combine that with the total technical drivel on their forums and you've gotta wonder WTF?
