The Unused FFVII Field Files - help

[Shademp]

I have been searching through the FFVII files (specifically, I have been comparing FFVII-j and FFVII-i) and found these files which I can't read via programs like Loveless, Makou Reactor or any other field file viewer. I am more than interested in uncovering what secrets these files hold but I have no programming skills to dig into it. Anyone up to the task?

Here is a list of what I found (ignoring unused fields which can already be read via Loveless). All have BSX, DAT and MIM files.

BLACKBGF
BLACKBGG
BLIN69_2
CONVIL_3
DUMMY  (DAT file is 5094 bytes smaller in FFVII-i than in FFVII-j)
FSHIP_26
HYOU14
JUNMON
M_ENDO
ONNA_1
ONNA_3
ONNA_6
PASS
Q_5
SUBIN_4
TRAP
WHITEBG1  (DAT file 9669 bytes smaller in FFVII-i than in FFVII-j)
WHITEBG2  (DAT file 6847 bytes smaller --||-- )
XMVTES   (DAT file 3040 bytes smaller --||-- )


What I already know:

I know that TRAP, XMVTES (and the change in FALLP from FFVII-j to FFVII-i) was mentioned in this topic:

I know that Onna_1, 3 and 6 can be entered in FFVII-j using cheats.

I also know that either BLACKBGF or BLACKBGG (not sure which) can be visited in FFVII-j.

Either whitebg1 or whitebg2 stands for this screen, also possible to find in FFVII-j.

But what about ripping the script from the DAT files? Or viewing the MIM files? Even if the files are incomplete, like the TRAP .MIM file, I want to view them. Surely I can't be alone to want to figure out what the fifth Gelnika room, Q5, holds.

You can use Makou Reactor for that, try "File -> Open Field Dir (PS)". With this menu you can open dat files in a directory.

Thanks Myst6re for linking me to the MIM file structure.

However this is, yet again, something I cannot use. Anyone up to trying this structure out and see if they can retrieve an image from any of the files I listed above?
