I want to know the answer to the following question:
What was the lockout chip number for the USA and Canada?
All the background I'm provided with is that "Since two types of lockout chip were used in Europe, European NES game boxes often had an "A" or "B" letter on the front, indicating whether the game is compatible with UK/Italian/Australian consoles (A), or the rest of Europe (B).". Is that enough to answer the question?
Answer: no
