Pretty sure that if you Google the make & model of the machine, the company will have some sort of replacement, upgraded BV available?
That would be easier than trying to get anything from Cash Code?
First, Cash Code's going to want the machine's specs, and most likely your registered repairer's license number, to have access to any firmware upgrade.
Secondly, you might need special programming equipment and software to flash an embedded IC chip...if that's the case.
Is there a programming port on the BV that would help you decide whether or not you have anything to flash it with?
If not, then your options would be severely limited to sending out the BV somewhere to be upgraded...where? I would say the machine manufacturer.
Sorry that I was not able to be of too much help to you.
Good luck!
