Qwertymodo’s version of the SNES digital audio mod is in stock and ready to ship! This mod allows for 100% clean, digital audio from all SNES games, except Super Game Boy and MSU-1 romhacks. It’s designed to be an easy fit for the SNES Mini, but can be installed in any version of the SNES with the S-APU audio chip. Also, the output is 3.5mm mini toslink, which means if you mount it in place of the RF jack on a larger SNES/SFC, it’ll be a 100% #nocutmod! The price is $40 and more info after the links:

The first thing to reiterate is this mod will not work with the Super Game Boy, or with the CD-quality audio from MSU-1 patches. That’s because both of those generate their own audio on the cart itself and mix it with the SNES’ analog output. It’ll still work with all other audio from the FX Pak ROM cart though!
Next, I realize many people might not even know mini-toslink exists! Admittedly, I’d completely forgotten about it until it was included with many MiSTer I/O boards! Basically, it looks like a standard headphone jack, but outputs the same digital, optical signal a standard SPIDIF jack outputs. I linked to the cheap cable I use that’s mini-toslink on one end and standard SPDIF on the other. You can also use this with audio receivers that have a “digital RCA jack” input; Just get a mono 3.5mm-to-RCA cable. And once again, this does not output analog audio, only digital.
And that’s basically it. All other info on SNES digital audio mods can be found in the page linked above and you should reference Qwertymodo’s pages to get the exact installation points needed!
