 In the Debug Rom for example, address BCC4E0 acts as the start address to the table. In order to reach the instrument set record, the game reads the halfword at BCC4E0 + (SequenceId * 2), then adds that to BCC4E0 to reach the appropriate record. Fortunately, this calculation can be simplified as being Table Start (BCC4E0 for debug) + DD + (SequenceId * 2) for all but sequence 0, where you'll have to subtract the result by 1.
