I'm trying a bit to also get cassette saving to work in MESS. For this it would be very helpful to get a wav file saved from the cassette output of a real BBC for a simple BASIC program.
Something like this would be great:
10 PRINT "MESS!"
*TAPE
SAVE "MESSTEST"
Currently the emulated BBCs can write data to a wav file, but attempting to load the file back in the emulated BBC results in incomplete reads.
Any help is greatly appreciated!
