Hi all i have been working on getting all the used field varibles mapped. i have been keeping some notes mostly on field items and what bits are toggled when they are picked up  . the notes contain the varible names from makou reactor field section , Black Chocobo Z vars and/or Real Offsets from save map. some contain additional notes on what else changes and a few are related to progression.

you can view the notes here or download them

if you have any questions about the notes feel free to ask . more will be added as they are discovered.

I considered writing a field script skimmer that would map out which variables are used in which scenes. I'm not sure how helpful that would be, though so I didn't do it. :P Maybe I'll take a crack at it. I'll have to skim through the wiki to find out how they're all referenced. Looks like a lot.
 
all these notes are from reading the scripts and noting what they change . then testing with BC and FF7 to varify the data is correct. (all this also needs to eventually make it to the save wiki. too)
 
I did start something like this but it does take a while to do manually. Although it seems a bit incomplete even in what it covers.

I will find this very useful.
 
About this, I wanted to edit the savemap page for FF8 (http://wiki.qhimm.com/edit/FF8/GameSaveFormat) to add the Shard's page. (But I can't because I have a 403 error.)

The variable list should begins at 0x0D70 on this savemap page (should because there is an offset error at 0x0020).

I found them at 0xD10 in my saves (I believe I was using notepad++, so I was looking directly at the file). Do different FF8 versions have different stuff in the save maps?

EDIT: NVM, you're talking about FF7.

I'm working on a full "which bytes are in use" list as we speak.  Which will include battle, world map, field and hopefully be a more complete picture of what's going on.  Perhaps others can then fill in the information for what the use is for (extra detail).

Speaking of which, it seems Field var [7] is the 2 byte write/read, and var [15] is the 1 byte read/write?
