/*
   apart from initializing data, structures below can be used to
   speed up access to data and let cc65 to generate better code
   e.g. if you have menu defined as TopMenu and you want to change the number of
   menu items use:
    ((struct menu*)&TopMenu)->number=newNumber;
   This will be translated into single lda/sta pair
