EDIT: I know this seems like it should be in Game Help, but it's not a problem I'm wanting to have fixed or whatever. I'm just sharing it, so in order to curb any confusion, I've changed the topic title, as well.
So this little "problem" happened again and reminded me that I wanted to share it with all of you.
Sometimes, at random, when playing NSMB, the sound will get louder and start playing "double", for lack of a better term. I'm assuming that some of the sound channels are reserved for one speaker with the others going to the other speaker.
However, when this occurs, it sounds like the whole game audio is playing through both speakers (if the aforementioned is true), but the right side will have a delay, so it's like you're playing the game with a loud echo... kinda like a "wet" grand hall mix.
It's kind of a cool effect and it only happens with my NSMB cart (which explains the topic title). Have any of you experienced this with NSMB on an old DS or with any games on the old DS at all?
