FF7/World Map/BSZ
[Lazy Bastard]: Using a hex editor, I've mapped out a BSZ file, namely WM0.BSZ - Cloud's world map model. Incidentally, WM1.BSZ is Tifa's world map model, WM2.BSZ is Cid's, and WM3.BSZ seems to be every other world map model, similar to a BSX in fields (though I haven't confirmed this yet).
There is a remarkable resemblance here to BCX format, so I should be able to create custom world map models fairly soon, using the same techniques I used in fields. [Update: I did just that; see Qhimm.com forum threads]
Akari: Perhaps you can use this data to implement a utility and functionality in Q-Gears?
Without further ado:
______________________________________
In PSX memory, WM0.BSZ starts at 14A600 (and ends at 14F3B7). Every 80-type offset in this file can be treated as such: offset minus 8014A600 equals in-file offset.

Note: In CLOUD.BCX, the above would be the end of the file. In this format, however, the Model Section
(with all its components) comes before actual parts/animations data, after which is texture data, which
comprises the remainder of the file.
Note: 'Model section', Animations runs into 'Skeleton Data Section'.
