So I found a chanting lotus flower in the woods and I'm trying to figure out how to reprogram the audio on it... It has 4.5 hours of audio(!) stored on a 16MB flashrom, and is driven by a chip called JL16B-083A. At first I thought/hoped it was just an AC1082 clone playing straight MP3s, but when I looked closely at how it was wired I realized that wasn't the case and is something else (see pic below where I've labeled the traces).I've dumped the flash - it doens't seem like MP3s, but it doesn't really seem like anything recognizeable at all... All I know is that it's 4.5 hours long, implying it's running at about 8kpbs. I've tried my best to search various Chinese engines looking for anything on this part, but have come up empty... Has anyone ever come across this chip before, or knows how the audio is encoded on the flash? Or how I might figure it out? Objective is to load it up with audio from the Conet project and possibly return it to the woods :)
