Hey Intrepid,
Pardon my ignorance, but how can it automatically fill in the tags? I thought Total Recorder simply captured the audio coming through the sound card. How does it get the song/artist info from the XM signal?
I don't think it would do you any good without the dissassembler. I only dissassembled a part of it. You can download IDA Pro for a free trial period and try it yourself. I seem to recall seeing a few free ones out there when I googled the topic.
I just downloaded a trial copy of IDA Pro and successfully disassembled TimeTrax Recast v1.8. However, I don't know Assembly code well enough to figure out what to do from there.
