Hello. I don't know if many people have noticed this, but the game Majora's Mask 3D seems to always output Surround audio no matter what Sound settings you currently have set up on your 3DS. Surround sound makes the 3DS output audio in lower quality when comparing to Stereo.

This is my conclusion after I compared how Majora's Mask 3D sound effects and Ocarina of Time 3D's sounded, and they sound pretty much the same (I compared the SFX that are common between both games). Plus, when you play Majora's Mask 3D and Ocarina of Time 3D using Surround audio , the audio quality of the SFX are very similar (if not the same).
However, when playing with Stereo sound, Ocarina of Time 3D sounds noticiably better, while Majora's Mask 3D sounds the same as before, even when changing the sound setting.
I made a more extensive post on the HCS forum regarding this particular problem, and a person told me that something similar happens with Pokemon X, where choosing Stereo would output Mono instead in that game.

So my question is if there is a way to play Majora's Mask 3D forcing the 3DS to play Stereo audio instead of always Surround. I tried checking the exheader of the game aswell as the .bcsar files to see if there's a byte or similar that forces Surround sound, but I had no luck. I've searched some pages on 3dbrew and so far the closest thing I found that could be related is s page that documented the DSP Memory Region, but I cannot do tests with it because I don't know how to find the data shown in the article (I'm using Luma's Proccess viewer).

This is a pretty particular case since it's the only 3DS game I know that does this (and I honestly think is intended) Besides, I can pretty much confirm that this does not have nothing to do with the console hardware itself, in fact, the difference is more noticiable when playing without the headphones (I use a regular old3DS).

As far as I know, the game code is responsible for setting up the audio, so that's where you should look.
Thanks for the replay. Yeah, I also thought on that aswell. Unafortunately, I don't have the skill to reverse engine that data nor there seems to be any documentation about the code on the internet (with code, you mean the ".code" file inside a decompressed exefs if I'm not mistaken).

I also tried to look to the proccess of the game, but I get lost pretty quickly.
