Nah, just load it on a supercharger.   Does CuttleCart 2 have some 
kind of "ROM" protection that a Supercharger might be lacking?

I'd hate to just go back to doing final debugging on Z26, and crossing
my fingers that my burnt cart won't have the problem.  I need to find
this and fix it but I have no idea how. 

On ,
the ROM of March 8th seems ok (well, it has another stupid constant 
bug for the initial ball speed 1/2 the time) but March 9th starts 
to go nuts on a supercharger. But like my other research has shown,
it's kind of an odd delicate situation.

Yeah, this is near the end of my DASM listfile:
