RPC-2, commonly accessible software is available that does not care about
region code settings.
Initialization was changed so software does not have access to the
decryption functions if the region code does not match taking the
decision out of the hand of the player software.
I read two narrations in the web:
"RPC-1 has no region code in drive but in software,
RPC-2 has region code in drive and enforces region
code match in hardware."
versus
"RPC-1 allows to change region code as often as wanted,
RPC-2 allows only 5 changes. Special software will read
and display videos from non-matching regions anyway."
Early drives typically shipped with the region code unset and commonly
you would
be asked to choose a region when you ran the playback software the first
time.
Could be that some drives did not limit the number of times you could
change the
region code. If there were such drives, the information available
indicated you only
had a limited number of changes going all the way back to the days of
needing a
special card that only did mpeg acceleration in order to play a DVD.
