NES Front Loader + NESRGB + NES EverDrive. Famicom Expanded Audio Mod???

Can you mod the front loader NES system for expanded Famicom audio without the Famciom2NES adapter??? I have a front loader NES and a NES Everdrive flash cart and has recently installed Tim's NESRGB mod, with this type of set up you can run a wire (with 22k resister) from PIN 9 on the expansion socket to 2 resistors on the NESRGB board, but im not sure if the Famicom2NES adapter (with the jumper wire) is needed to get the extra audio mod to work, does anyone know for sure?

Obviously i dont have the Famicom2nes adapter as im using a front loading NTSC NES console and a NES Everdriver cart which you can load famicom games onto which have the expanded audio channel, hence my question about the removal of the famicom2nes adapter in the mod process!

 

I've been doing some research on this too. I've currently waiting for tim to ship out my rgbnes board. I've read you just have to connect pins 3 & 9 on the expansion slot with a 47k ohm resistor.

I've also read that some people were using 94k/95k resistors with the everdrive but some say to still use the 47k.

I plan on running a 100k linear potentiometer like this one: http://www.digikey.com/product-detail/en/P16NP104KAB15/P16NPA-100K-ND/2712643
This will just give me total control, and turning the knob roughly half way will get me the 47k and turning the knob roughly all the way will get me to 95k. And if a certain game I'm not digging the audio I can easily turn it down to my tastes.

 

As long as you have the right pins hooked and the proper resistor it will work. The Famicon2NES adapter doesn't do anything more than change the cart slot.
