How do I open luac files?

Post by neoeric »

The game's name is Alchemy Stars.
I guess these files are mostly story text and tooltips but I'm not really sure about it.
There are two kinds of them, one which is filled with alien words and one which is filled with hex numbers.
I used luac decryptor to both of them, but neither seems to work.
If anyone knows how to handle these files, please give me some help. Thank you!

The files are also encrypted/compressed. You would need to remove that/those protections first before running them through any Lua decrytor.

Then will it be impossible to read them without knowing the way they are encrypted?
I hope there are some hints within the files...

The files alone wont really tell much about what is happening since it can be all kinds of things or multiple layers of protection.

It generally would require seeing the main Lua library used by the game to see how its loading the files to tell what is being done to them.
