Re: [B2-devel] Two dreams of mine

CW--

You bring up an excellent point: my goal is not necessarily to emulate  
the NeXT hardware.  Put simply my real goal is to be able to run some  
m68k-only NeXT applications, and since we already have x86 versions of  
NeXTSTEP/OPENSTEP, it may be better to emulate just the CPU in  
NeXTSTEP/OPENSTEP-x86 itself, rather than trying to emulate the entire  
platform.  This would be similar to what Apple did for the m68k-to-PPC  
conversion, which allowed the direct execution of m68k Mac OS apps on  
the PPC platform.

I'll check on QEMU - thanks.
