Is it possible to make a bms script to extract/repack files from the file DATA.BIN of the game Second Novel?
I tried myself, but I'm no programmer and I haven't any experience in reverse engineering (beside using already available tools).
I think it uses an LZSS compression, since there's actually "lzss" written at the beginning of the file:


Here is a link to the file.

I might actually translate this game in my free time, so I need the scripts and the images that should be edited. I think they're all inside DATA.BIN, but I can't be sure if I don't see what's in there, you know

Thanks in advance!

Thank you, it works like a charm!

Now, there's only one problem left... how do I decrypt and recrypt the lua files? I tried luadec, but it didn't work.

They are compiled lua scripts so you have to try other decompilers (every decompiler supports a different version, there are many)
