Here's an idea: since the ROM can also be transmitted calc-to-calc, can't
someone write a link program that extracts the ROM (or the Flash data
stream) from an already flashed calc? The same link program could then
simulate a transmitting calc when flashing.

This is of course illegal since you'd have to send the ROM to someone - but
that someone will so far always own a 92+, at least until Tiger supports it.

PQF Quote follows:

There have, in the course of decadent history, been many large wigs, often
with build-in gewgaws to stop people having to look at boring hair all the
time. There had been ones big enough to contain pet mice or clockwork
ornaments. Mme Cupidor, mistress of Mad King Soup II, had one with a bird
cage in it, but on special state occasions wore one containing a perpetual
calendar, a floral clock and a take-away linguini shop.
