Post by KusanagiRuiz »

Hello, such! I would like to know how I can open these files of this game, what I am looking for that I want to extract the animations of the game, the images and I could extract them, but I would like to know if there is a script to extract or translate them. Greetings.

I add some files.

lua & bobj.zip

lua has a 32-bytes hash at the beginning followed by sensleless unaligned data, probably encrypted.

bobj has the "BMCX" magic, content is not encrypted, and it's not an archive. It's almost all text, try to take a look at it with notepad++ just for fun.

Ok thanks. Is there any way to decrypt the .lua files?

Reverse engineering, you need to wait someone who wants to work on it.
