Notes and Comments

Note 1 (field names)

Several of the fields in the format specifications are named "WBsomething". This is because of the string "WBOR" which appears regularly throughout every *.tpa file. The "WB" in the field names thus represent the string "WBOR".

Note 2 (number of WBBlocks, WBTables)

The number of WBBlocks in a given file should match the number of WBTables, but sometimes it doesn't. This is because the same sound data will sometimes have two, and possibly even more, Sound IDs. When this happens, the number of WBTables is always higher than the number of WBBlocks.

Note 3 (first WBTable)

The first WBTable always points to a block of zeroes that are either 16536 or 22120 bytes long. This first, missing entry is the default sound played whenever the TPA is missing the sound called for.
