[Vm-dev] InterpreterSimulator

[Florin Mateoc]

Hi Eliot,

Thank you, VMMaker.oscog works better, indeed.
I still got an error while executing:

(StackInterpreterSimulator new openOn:
'F:\Smalltalk\squeak\Squeak-4.5-All-in-One.app\Contents\Resources\Squeak4.5-decompiler.image') test

Do I need any additional settings?


Here is the erorr report:
