Re-formated dump.
Here's a re-re-reformat of the first dump.
Not only are there ACKs, but some frames also seem to be truncated (or follow another format). The big difference is in bytes 2 and 3. Byte 2 is almost always = frame length - 4 and byte 3 would be the "frame type" after all...
Anyway, considering only full 15-byte frames, it's now obvious that byte 4 is track number.
Status of the 15-byte frames decoding :
0 : ?? (3Dh or 3Fh)
1 : frame id ?
2 : frame length - 4 ? (0bh)
3 : frame type ? (47h)
4 : track number
5 : ?? (01)
6 : ?? (00)
7 : elapsed time from CD start, minutes (bcd encoded)
8 : elapsed time from CD start, seconds (bcd encoded)
9 : ?? (constant per track, 00 for track 1)
10 : ?? (00)
11 : elapsed time from track start, minutes (bcd encoded)
12 : elapsed time from track start, seconds (bcd encoded)
13 : ?? (00)
14 : CRC ?
Seems we won't be able to display ID3 tags :-(... but well.
