Memory for the TWIGZ Engine is stored mostly in XMS memory. EMS memory is used mainly as a secondary screen buffer and for some other graphical memory functions. Below is a table explaining how, exactly, XMS memory is used by the TWIGZ Engine. (Note: All items in red represent the XMS memory "handle" that the TWIGZ Engine uses to access those areas in XMS).
