Edit .SAD audio files in professor layton pandora's box

Sorry for the late reply. I've done undubbing all of the DS Layton games not too long ago (search for "Professor Layton DS UNDUB collection (updated)" if you're curious) and discovered that to avoid this issue you've described you need to use .SAD containers from the Curious Village and inject your modded audio in those. A tad tedious but it works.

 

Did you use the American or British versions?

 

@AcuteBulbasaurappears Both.

 

I found the QR codes but they brought me to nowhere

 

Do you have the finalized roms?

 

You're supposed to go through decoding the "QR code -> b64 string -> QR code -> b64 string" chain and put together the URL as instructed at the bottom of the post.
