Thanks heaps,
Bruce.
Your best bet is to reuse the ROM's that you have. Peel off the
labels, erase them and re-burn. Cross your fingers that none will
fail but expect the worst because it does happen. Remember to retry
the failures a few times because they can eventually work.
Repeated failures can make the ROM's slower to read but that's a whole
other discussion. I always double-burn mine to be sure the bits are
clearly set and will read quickly.
