Where to Buy:

The Moddern Castle
Version
NES Front Loader - Stock (not RGB modded)

Use a short wire or component leg to jump the pad to pin 3

NES Top Loader - Stock (not RGB modded)

The Top-Loader doesn't have a real amplifier for audio, so you can try muxxing it into pin 1 or pin 2 of the CPU.

It was never designed for this, but it certainly won't harm anything.

NES Front & Top Loader - RGB Modded

Use a jumper wire to connect the expansion audio pad to the open via next to component J5 on the RGB board.

    This small interface is designed to allow easy acquisition of expansion audio from a real Famicom cartridge.
