   Well, the game currently *is* modularized.  In fact, the executable is   
   currently split into multiple parts, but, currently, all parts are loaded in   
   at once.  The main executable loads first, then two stubs loaded into the   
   first k, then some strings and    
   misc. data behind the I/O and kernal ROM to be accessed using my cc65 Hidden64   
   library.

   I used to comment extravagantly but recently stopped.  I don't know why.  :(

   Well, I have my own input routine called AltInput for cc65.  It is a front-end   
   to my CBMSimpleIO library.  Both are at https://sourceforge.net/   
   rojects/cc65extra/files/ui/.
