Hacking the Famicom & NES for split audio outs
Follow this simple diagram to add split audio outs to your NES or Famicom…
Open up your NES and disassemble it down until you have it sitting there on your work surface as a bare motherboard, locate chip 2a03 and check the following diagram:
Once you have done the mod, the NES/Famicom’s sound channels will output separately on one jack split as follows:
- Channels 1+2 will output from Jack 1
- Channels 3+4+5 will output from Jack 2
Using a split Y cable to headphone jack plug you can record the NES’s sound into your computer now at a MUCH higher quality than before…
You will have to mix the audio down to Mono tho - as the NES is a MONO system… and the sound separation is not natural… Unless you are playing back your own music of course and have taken advantage of this :)
You can also do this mod by soldering to the underside of the 2a03 chip, make sure you have the right solder points for the legs tho - I don’t want to be responsible for you frying your laptop by accidentally connecting something to +v :)
