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: | ||

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 | 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). | ||
