I want to know the answer to the following question:
How were adapters used to get around PAL region restrictions?
All the background I'm provided with is that "Alternatively, disconnecting one pin of the console's lockout chip will prevent it from locking the console; hardware in later games can detect this situation, so it later became common to install a switch to reconnect the lockout chip as needed.". Is that enough to answer the question?
Answer: no
