[Coco] RE: [Color Computer] Other WAV2CAS

[Stephen Blunt]

I managed to read all but one commercial tape (Scramble) and a few wip files
of various programs.

I managed to get them all to work in an emulator. I tried the wav2cas and
only some one them worked. Additionally I know that some of the recordings
were very noisy but once I output them through the emulator I had much better
luck.

I did find that recording in 8bit mono often didn't work. I standardized on
16bit stereo and then split off one channel. My wav files are huge but it was
the only way I got all the bulk of the tapes to work.

Considering the CCR-81 I was using was just as old (I bought it off ebay) and
another ccr-81 I have no longer sync's, I was very happy with the amount I
did manage to archive.
