First of all, is there already one? So, well, I have my own ACNL "Sound" archive, and inside it are two (accurately) named folders and one .bcsar: –stream (.bcstm files, of course) –GardenSound.bcsar –asr I cut the .bcsar with 3DS Audio Ripper and got these folders: –bcwav –cseq –csar Their names all are hexadecimal-esque, but in a hex editor you can see some human language titles. Stream, bcwav and cseq all open in foobar2000, asr and csar don't. I have no idea to handle those, so a hint would definitely be appreciated. But that's not the main question: I have converted all .cseq files to .mid MIDI files. But the built-in soundfonts all can't substitute the ACNL sounds. Which are all in the bcwav folder… But not all tracks there are sounds. Yay..! I can imagine I'd have to pick the fitting sounds manually, but first, how, and second, what's the best way?
