Hi Tony,
my part has been just brute force.
The important part is on your side. Without the script I would not have begun that work ...
I am going to compare the ASC-CAS files.
To me having 2446 out of 2448 is simply extra! We have just a 0,1% of error cases, not thta bad!

cheers

Thanks a lot, Stew that's good to know for next bacth process ... There is a way to find out problems: The WAV files use to be 55-75 times the CAS file, so small files are error candidates. I have converted all of the files to WAV format using XRoar while reading an interesting book! Anyway I have f...

@Ciaran The CAS2WAV.EXE doesn't give any error message processing the JMPMFL.CAS but the resultant WAV doesn't load properly in XRoar with Orchestra90cc Is there any way of making XRoar return an error code to the batch command that has called it? That way with if %errorlevel% neq 0 PAUSE I could ha...

Hello, I am in the process of converting the 2448 ASC files into WAV files ... I have found an I/O Error when loading a file into XRoar It is the JMPMFL.ASC that converts silently into JMPMFL.CAS and then while converting to WAV with XRoar shows for a small moment the I/O ERROR message and immediate...

Hi Ciaran, disregard previous post. It was my own fault, sorry :-( I was using this command for %%a in (*.cas) do ( ..\..\xroar -machine dragon64 -extbas ..\..\..\XRoar\ROMs\d64rom1.rom -altbas ..\..\..\XRoar\ROMs\d64rom2.rom -nodos -tape-rewrite -tape-write %%a2wav -type "SKIPF\n" -timeout-motoroff...

You could use XRoar for this maybe (yeah yeah I'm a one-trick pony...): xroar -nodos -tape-rewrite -tape-write filename.wav -type 'SKIPF\n' -timeout-motoroff 1 filename.cas Edit: except... there seems to be a bug ;) Hi Ciaran, no good news, sorry. I didn't use any of the created WAV files nor did I...

Hi Tony, I have tested the two cas you uploaded and work well in XRoar with Orchestra. Then I used the new script to convert AAODDS.ASC that had given 'header' problems and now it is well converted and plays nice too. So, congrats! You got it! I like the idea of widening the header with 80 chars $55...

Hi Tony, glad to know you have a patch that solves the 'problematic files' I am doing my firts steps on Perl, fortunately it is a very C-like language, but it has some tricks related to I/O and search/substitute strings that need some internet help! Honestly, after reading your script some hundred t...

that's right. Now it seems that I could plan to 'verify' the converted CAS files with a small java app. Or maybe better, try to learn perl and see what does Tony's script. I don't need the WAV files immediately, it was just a step to get them converted into ORC files and saved onto DSK in my CoCo, s...

The last byte in the block is the CRC of the block. The structure is as follows: 0x55 Lead 0x3C Block Begin 0x?? Block Type 0x?? Block size Size bytes of data 0x?? CRC 0x55 Trailing byte So, most probably, the script isn't counting on the CRC byte and does mistake it for a data byte. Good point, Ro...
