Need help for extracting model files - [Lapis Re:Lights]

[XiaoYe]

I've been trying to extract the game assets with Asset Studio, however, it can't be loaded with Asset Studio.

The first byte of every 7 bytes is XORed with 0xee.
Script for decrypting the files, it works with any xor key:

Code: Select all

encryption xor "UnityFS"
log MEMORY_FILE 0 7
getdstring KEY 7 MEMORY_FILE
encryption xor KEY "" 0 7
get SIZE asize
get NAME filename
string NAME + ".decrypt"
log NAME 0 SIZE

Feel free to set a better extension, I choose .decrypt but you can use whatever you prefer.

Uh, some failed to decrypt properly......

Is there anything to decrypt them well cause....they have different keys...

[aluigi]

Because the length of the non-xored bytes changes for whatever reason and probably also other things change.
It's just a waste of time without the correct algorithm.

[LuigiwithTHEDoNg]

is there anything i can do cause....i really want to rip the assets privately....

[aluigi]

Maybe someone will find a rule for automatically calculating the xor key working with all the files, I have no other ideas at the moment because a file I checked didn't differ only in the length of the key.

Okay, i think this guy can figure out why they are xored repeteadly https://github.com/MalitsPlus/HoshimiTo ... ster/lapis
