Unlike CWAV, if there are 2 channels in a CSTM they alternate every 0x2000 bytes of the DATA partition starting at 0x20.
Additionally it introduces a new partition called SEEK which comes right before DATA, so a CSTM would be ordered like this:
Additionally it introduces a new partition called SEEK which comes right before DATA, so a CSTM would be ordered like this:
* DATA Partition
* DATA Partition
By default this means that 0x24-0x2B in the CSTM Partition is the SEEK position and length respectively, and DATA position and length follows it. (in a CWAV 0x24-0x2B is usually the DATA position and length)
