How to get key to extract info.psb.m (and body.bin) for ripping Koihime Enbu Steam?

[CG33144]

A beginner at this and searched the dlls and cdxes but to no avail, desperately need some help
Game is Koihime Enbu RyoRaiRai Version 3 on Steam PC
Here're some files that I predicted might have the MDF/MFL key alongside the one of info.psb.m examples below
files.zip

Thanks for providing all required files at once.
It locates in the .exe file. The key is gYk,1H.6x and the length is 97.
.\PsbDecompile.exe info-psb -k gYk,1H.6x -l 97 windata_eng_info.psb.m
To be honest it's the first time I saw punctuations in a key. The M2 was making some useless try to make it harder.

It worked flawlessly, thank you very much!
It's definitely strange to see punctuations on a seed/key and also not in 11 (131) length, no wonder why I missed it despite being in the open.
some of the graphics files are blurry and also in psb.m tho, how do I extract them completely as well?

Blurry doesn't sound like a FreeMote bug but you can upload a PSB sample for that if you think so.
To extract all data in .psb.m and body.bin, append -a (extract all):
.\PsbDecompile.exe info-psb -k gYk,1H.6x -l 97 windata_eng_info.psb.m -a

Hmm yeah, tried again and it apparently can't extract files like these even with -a append
ED01.psb.zip
SFF.zip

KANU SFF.zip

Feels like some of these were made from different engine, like Nekopara's KirikiriZ

Okay, it's not "blurry" actually, it's a new image type which is not yet supported. I guess it may take a while.

@CG33144 Unfortunately your uploaded files are not decryptable directly. Is it using another key?
You may have to upload the whole psb.m + body.bin (via google drive or something).

It's weird if you did get these files via PsbDecompile info-psb because this command will try it's best to output PSB instead of MDF or MFL.
But you still got MDF/MFL. If they come from psb.m + body.bin, the key is undetermined (the relative path is a part of key, but this info is lost if you only upload such file).

Or, you can use PsbDecompile info-psb -a and upload all .psb.m.resx.json files related to all your previously uploaded files. These resx.json files recorded the actual key used.

[CG33144]

There's no .psb.m.resx.json in my files before, so I'll just give you the raw .body.bin in drive instead.
Can only upload one of em currently tho, sorry bout that. Tho all the graphics files I need are encrypted inside it anyway.

As the inventor of PSB format, the M2 is using such heavily modified things in their own games...
It's a waste of time to support them - there is almost no chance for these modifications being applied to any other company's games.
I will take a try till run out of patience.

[CG33144]

If it helps, I recall someone apparently managed to rip em by brute force and said that the engine is really similiar to M.U.G.E.N engine. Specifically, the modified Ikemen fighting game engine.
Other than that, I dunno. Nevertheless, thanks a lot for your help in finding the key.
