The first thing to check is whether the chip that holds the region
code is flashable. For example, look for chips with 29 (flashable) or
27 (non-flashable) in the part number.

Another thing you could do is to find firmware of the same revision
for different regions and then compare the two. Hopefully there will
be a difference at only one byte. By knowing the actual region codes,
you may be able to decipher how to encode for region 0. Note that
there may also be a checksum byte(s) which you would have to
recompute.

Still another way would be to do the above for a DVD player using the
same chipset. Then search for a similar looking code block in your own
Denon firmware.
