NESRGB on Toploader w/ Expansion Audio using NESRGB Audio
by on (#158522)
Topic kind of says it all. I had someone else install my NESRGB kit on my Toploader and I (for some reason..) opted to not have them put in expansion audio, I guess because I have the HiDef kit which does it internally. But as soon as I got it I wanted to put it in. I soldered in the resistor to no avail then I noticed the modder utilized the NESRGB's audio circuitry and I can't find the information about modding that for expansion audio or if it's possible.

Thoughts? :|

Basically go pin 51 -> 1.2k Ohm resistor -> spot on the NESRGB with 2 resistors shown in this image

I think that should do it

Yep, I did it twice on both of my NES consoles. Works great.

Remember to keep the resistor lead/wire going to the rgb-board as short as possible (I wired the resistor directly to the board) to keep the noise at a minimum.

Sorry for reviving this old post, but does anyone have the picture that is missing from AaronE´s post?

the one that shows the "spot on the NESRGB with 2 resistors shown in this image"

Thanks!

This is how I personally did it:
