How to know which block fails (WAV to CAS convertion A8CAS)

[manterola]

That's the question... I am trying to understand how A8cas works.. and I really don't know if everything was ok, it was a problem... where is the problem, etc.

Thanks!

If you are loading the CAS file into Altirra then with the debugger enabled you will see 'CAS' trace messages as blocks are loaded but you can also enable other logging, e.g. '.caslogdata', to provide extra detail

I would presume a failure would produce a shorter file.

From the Cas file format there's headers for each chunk.  So probably several bytes fixed overhead then 138 or so bytes per record.

 

I'd have though such utilities should give you some verbose logging option maybe?
