how do you run the simulator?
See http://www.squeakvm.org/svn/squeak/branches/Cog/image/VMMaker-Squeak4.1.imag... the VM Simulation Workspace there-in. Substitute StackInterpreterSimulator for CogVMSimulator and you don't need the Bochs plugin.
Long time ago we had to use an MVC image and after it got broken and we could not use it anymore. Now in Pharo we do not have MVC so are we talking about the same?
One openAsMorph method is all it takes.

Hi All,
now I'm successfully simulating the LargeIntegers plugin I'm hittingwhat I consider a bug in CArray, used to model C pointers in the simulator. The first problem is that CArray>>#+ & #- return an integer value, not another CArray, (in C (char *)(exp) + n is still of type (char *), not int) and that the addition/subtraction doesn't scale by the unit size (in C (type *)p + n == (type *)((char *)p + n * sizeof(type))). The second problem is that << >> * & // are meaningless on C pointers. Anyone think of a good reason why I shouldn't a) rewrite CArray>>#+ & #- to read
- n ^ self shallowCopy += (n * unitSize)
- n ^ self shallowCopy -= (n * unitSize)
(since e.g. += increment
ptrOffset := ptrOffset + increment)and b) delete CArray>>#*, #//, #<<, #>>, #bitAnd:, #bitOr:, #bitShift: &
#signedBitShift: ?
