Seems like the answer is basically no, but... you can fiddle around with wav2cas and playcas and a hex editor and... easy peasy ;-)
Basically the tools need to be adapted for the Model 100 and this would work. Might be a fun little project... port wav2cas to some language other than Ruby and make it work for m100 files. For extra points... make it work as an Android app... -- John.
