an ultimax cart starts via the hardware reset vector at $fffc - so if you find
a vector there that points to code that looks like startup code, perhaps thats

respectively

I recognize that a class of criminals and juvenile delinquents has taken to
calling themselves 'hackers', but I consider them irrelevant to the true
meaning of the word; just as the Mafia calls themselves 'businessmen' but
nobody pays that fact any attention.
