   Great :-) Congrats!

   As already commented on YouTube, I'm proud to see my digitized sound player   
   put to a good use here :-)

   Maybe I don't get your use case right, but in general my code in   
   https://github.com/cc65/cc65/blob/master/libsrc/apple2/waitvsync.s is   
   supposed to be "the" correct solution. Even 4am (!) adopted its //c logic   
   for Total Replay after an in depth discussion.
