Quoting from the V3 instruction sheet:
Did you find a secret code?
At the shop counter screen, press button (A).
Then, press button (A) quickly three times.
When the shop owner’s face appears surprised, punch
in the secret code to reveal a new item.
[Note: A = left button, B = middle button, C = right button]
