Of course, guess I wasn't sober enough to catch that on the first pass.
And yes, boot loader is in the high page. Time permitting, I'll dig
into it and see what I can get done.

I built a balancing two wheeled bot using the 2560 written using the
Arduino IDE. It would be a lot of work writing all the library
equivalents but, if we get enough snow this winter, it would surely help
with the cabin fever.
