About BCSTM-Player
Without a DSP dump on the SD card there's no sound.
The author's known bugs: it runs at 30fps on an original 3DS, the licence screen runs off the edge, and you can get stuck in the licence menu. tobid7 wrote it. cheuble made the original BCSTM-Player, and some of that decoding code is still in there.

Last words
If you encounter any issues (including crashes or just bugs), report them in an issue please.
If you want to want to have your language supported as well, feel free to open a pullrequest with the json of your language. But keep in mind that i will remove some strings in some cleanup commit
I will get on them when I have time but for now i need to step back from coding. I always do too much projects and other stuff at once and it is finally time to take a break.
And finally:
Merry Christmas and happy holidays to everyone 🎄
