If this doesn't work, Python may have not been installed correctly. The .py extension should automatically tell Windows to start the Python interpreter when a .py file is started from the Windows Explorer. Rather than a batch file, create a shell executable that invokes the Python interpreter on the evbu.py file. The limitations of EVBU are derived both from the program itself and from the PySim11 simulation engine. There is no special partitioning of memory.
All memory is readable and writable.
This need not be fixed in the engine, however, as the EVBU interface can hook into PySim11 to implement memory restrictions. Several of the differences are considered enhancements, while others are simply due to laziness. There is, for example, no assembly of instructions supported by the ' ASM ' command, just disassembly. The ' -h ' option prints a brief summary of available options. The starting address can either be set manually using the ' RM ' command, or via the S19 file using the ' END ' directive, or via the ' -s ' EVBU option.
