I modded my US NES to accept enhanced audio from Japanese carts. Here's a PDF explaining the project.

enhanced audio? The Japanese ones had better audio?

On a few games. And the disk system also used these audio pins. The pins allowed for external audio chips to be used inside the cartridge. On the US unit they moved the pins to the expansion port so no cartridge could use them.
