This is a good idea, but it would not be simple to do. I know that TI put a
protection system so that only regular flash updates can modify the flash.
They did that because some of the futures updates will be for sale, and they
don't want them to work on any TI. Every TI92+ has an unique serial number,
and when you by an update you give this serial, and then they sell you the
update which work only with yoUR calc.
So, we would have to break the protection first...
