*Moved all data from this post to posts 14-18, after fleshing out all data*

sorry if this is a noob question. by finding this out are we basically unraveling/documenting a source code for the game

So, my questions are:

1. Could someone verify my conclusion regarding the BSX header/skeleton data conflict, and if I'm correct, update the wiki page accordingly?

2. Why did Akari skip Model ID 3's model data in Q-Gears? Perhaps only Akari has this answer...

3. Could someone explain the details of the 'skeleton data' and 'animation data' sections? Particularly, I'm confused about the very beginning of each, which per the wiki page leaves me lost as to the rest (as it's all determined by relative offsets to consider the sizes of previous data).

4. Could someone correct the line of pseudo-code comment on the wiki page which says '(12 bix fixed point)' to read '(12 bit fixed point)'? Just a minor typo correction.

Not the source code, but the general structure of data contained in the game's files. I'm interested in this specific subject as a tool for my prequel mod, but there are plenty of reasons for wanting to document the details of field models (for example, changing, swapping, or replacing them with those of others, or new work entirely).

Because game use data from sector 7 of dat file instead of BSX data. When I wrote exporter i make it work like the gme engine.

Ah, I hadn't looked into sector 7 of DAT files. Thanks.

Soon as I can. I have some code for BSX in Makou.

As in, for the next release?

It's in my TODO list.

Can't wait to see it. I've mapped out CLOUD.BCX as a sample, and I'll post that in a new thread as well.

Thanks to wiki access, I've corrected the BSX header on the relevant wiki page.

I'm going to map out every inch I can of MD1STIN.BSX, flesh out my original post in this thread, and add this and the CLOUD.BCX stuff I've done as samples to the wiki. Then I can finally get back to work on my mod, heh.

Interestingly, Model 3 uses Model 2's skeleton and animation data (as in, it references the exact offsets Model 2 does). That could really throw off someone's mapping of a BSX file.

Update: Apparently, this happens quite a bit, especially with animation data.

Using Akari's notes from Q-Gears, the source from Micky's BSX/BCX viewer, information from the wiki

(http://wiki.qhimm.com/FF7/Field/BSX), snippets of things from across the forums, and my own logical deduction,

I've broken down MD1STIN.BSX (BSX file from the first field encountered in the game) as an example of BSX structure. In the process, I've come across a few

things I'm curious about. Without further ado:

'BSX Header Section' [at offset 0x00000000]:
