    I tried using foobar but it doesn't sound correctly

    Any ideas?

    Considering you tried to use Foobar, this must be a video of some sort? If so, you're in the wrong section. You want computer help, not 3DS help.

    Anyways, the only .mca info I can find is about Minecraft, and I highly doubt they're related. Where did you get this demo? Is it "legit?" Can you tell me where you got it without breaking the site's rules?

    Foobar2000 . I think its a music player since it plays brstm using vgmstream

    I got the demo from "that iso site" . Its a JPN demo thought

    The link that you're referring to is currently down, so I don't know how to help you. You opened the .rar and inside was a .mca file? And it's supposed to be a video of the gameplay? Or is it an actual game demo? Because if it's a game demo, I have no idea why you'd be trying to use Foobar2000. If it is a game demo, it's odd that it's not .3ds, .3dz, or .cia, but I haven't been keeping up with homebrew lately so I don't know what kinds of file formats you kids are using nowadays.

    Nah, I dumped the Romfs of the CIA, explore it and found the .mca in \sound\stream\bgm\data

    Oh, that completely changes things. After googling "3ds mca" I came across a program that might help you (or not, I know nothing of the inner workings of the 3DS). https://www.hcs64.com/vgmstream.html If this is the vgmstream thing you mentioned and you already tried it, then sorry, but *shrug* I give up.

    Yeah, already tried it. It sounds crackling and bitcrushed.

    If you are still interested, .mca files need to be "fixed" before they play in vgmstream correctly

    For most it's 8 bytes needed to be removed, but I've noticed 4/8/16/20/24 bytes that need to be removed from individual files. It's a trial and error kind of thing.

    have a look at https://gbatemp.net/threads/425059/ my tools contain an mca2wav.exe that succesfully converts mca's from monster hunter 4 and monster hunter x (generations). maybe your mca's work too ;)
