Well, starting to figure out archives so I guess I'll start with the very simple files
There are two archives that are unencrypted/uncompressed (textures/mesh), which contain small things but I guess it gets you somewhere.
Code: Select all
#touhou sky arena
#for mesh.gpk and texture.gpk only
get files long
for i = 0 < files
getdstring name 0x104
get size long
get offset long
log name offset size
next i
The rest..lol I don't even know what it is.

looks encrypted best bet is just use 3d ripper dx.

lol that's no fun.
Well, some other people are interested in translating it to chinese so maybe they'll figure something out in the future.

Ok I'm going to try cracking this by brute force and guesswork after reading the DGTEFF again (cause there are 5 more models in the next patch)
Some things are done that make it a little more manageable:
-someone already unpacked it, so the contents are known
-the number of files in the archive is known
-the filenames and filesizes are known
-there are unencrypted archives, which may provide a hint
First I started by highlighting arbitrary bytes and noticed that the number of results matched the number of files.
So ok, that might actually be part of the filename. It is known that unencrypted gpk archives store strings in 260 bytes.
In fact, the BMS script I wrote for those is just
Code: Select all
get FILES long
for i = 0 < FILES do
getdstring NAME 260
get SIZE long
get OFFSET long
log NAME OFFSET SIZE
next i
So now I just need to figure out how to decrypt it.
But...lol hmm I'm not sure how that would work.
The following archive contains 24 files, and it is known that strings are stored in 260 bytes.
Now I should probably get the patch files.

Got a hold of the guy that wrote the unpacker and repacker.

Will require insani.py

Trying to write a quickBMS script but there's too much XOR'ing

Can you send me the unpacker & repacker because the links are broken.
