OK, fair enough.  Let me rephrase my question:

That's what I've always understood "frying" to be.

But can you really call the Space Invaders two-shot behavior a  
"frying" behavior, since it does not depend on the state of the RAM,  
but only on the fact that Reset is held down while power is engaged,  
and it's completely repeatable and consistent?  (It would also be  
really cool if Stella tracked the state of Select and Reset when you  
turn on the (virtual) power, if it doesn't already.)
