The cool thing with the cassette support is that in addition to supporting 
.cas, .wav files are also supported directly.  It is actually easier to deal 
with .wav files directly because despite the theory, .cas files are not 
actually a stream of 1200/2400Hz pulses in practice.  I suspect that the 
.cas support in Jeff's emulator was implemented by patching the ROM's CASIN 
and CASOUT routines.

If these issues are the case, then these are bugs, plain and simple.  I've 
recently gutted MESS's and Imgtool's file format handling to make it more 
modular.  Now, if a new file format appears to compliment JVC/VDK/DMK, it 
can be added in a modular way and both MESS and Imgtool will immediately 
inherit the support.  Ditto on the cassette side with CAS and WAV.  
Unfortunately as Tim can attest to, new code means new bugs.  These will 
have to be squashed one by one.
