Super Robot Wars V (PC) .cpk encryption

[anakronus]

Now that Super Robot Wars V has come to PC and I would like to rip some assets and translate the game to my language, however I've hit a roadblock, the game's cpk archive contents seem to be encrypted (No obvious pattern in .DDS images), I tried my luck with some RE but it quickly got out of my league so I came here looking for help, thank you in advance :D

I've attached a cpk file (from SRWV_ROOT/data/statusimage) for reference.

[aluigi]

Have you tried using CriPakTools?

I confirm that there is an 8bytes pattern in the dds files extracted with my cpk.bms script, that's usually used in blowfish encryptions, but I don't know if it's something specific to the format (like it happened with a Naruto game as far as I remember) or specific for this game only.
I'm sure the other users can provide better support.

[anakronus]

Yeah, CriPakTools can get the files out, but they still are unreadable due to encryption, and I can confirm is encryption as the Vita version of the game does not have any problem when extracting data.
Furthermore, reading the forum I came across signsearch and the program found this:

I'm not sure how to proceed with this info now however.

[aluigi]

Try uploading SRWV.EXE, maybe some users will take a look at it and get the key.

[anakronus]

Update on this, I got the key! It was a weird process powered by insomnia and perseverance, but it was really fun!

[aluigi]

Feel free to share, in case someone else is interested.

[anakronus]

Oh yeah, if someone needs it, the key for the game is:

Code: Select all

SRVW Steam Game

very simple, actually xd I also went ahead and checked Super Robot Wars X's key and you can actually guess what it is based on this one.

It's blowfish encrypted, you can use a simple quickbms script like these:

Decryption:

Code: Select all

encryption blowfish "SRVW Steam Game" #Use the key "SRXW Steam Game" for SRW X
get SIZE asize
get NAME basename
get EXT extension
string NAME + _decrypted.
string NAME + EXT
log NAME 0 SIZE

Encryption:

Code: Select all

encryption blowfish "SRVW Steam Game" "" 1 #Use the key "SRXW Steam Game" for SRW X
get SIZE asize
get NAME basename
get EXT extension
log NAME 0 SIZE

If what you are planning is a translation the scripts are inside SRWV_ROOT/Data/STAGE/STGEST_EN.cpk, with the first file being a table and the chapters are separated .lua files (once parsed the table), object descriptions are inside SRWV_ROOT/CommonData/ShiroData/LanguageData/EN/LT00_EN.cpk and the menus on SRWV_ROOT\Data\AIDDATA\EN\SysText.cpk (first file, with a BLTU header)

If you actually want to translate it and can figure more of the game, let me know!
