Almost all files in FF9 has structure, which starts from 2 bytes DB (hex numbers). This record points, that after we'll have pointer list, which points to different data sections in the file (data can be sounds, TIMs, models, etc).

|}
Pointer is a number, which represent how many bytes from current position there is target data. Current position in this case is first byte of this pointer.

Data, where points this pointer begins with 2 bytes, first byte indicates, what data type we have, and second is count of objects of selected type.
