Hello. I searched and did not see anything related to this topic. I would like to work on extracting the files from FROM SOFTWARE's Armored Core games, starting with 3. Models, textures, audio, etc. However, I am new to this, so I'm not sure how to start. I'm currently stuck trying to figure out how to extract the BIN file (Texmod just gave me thousands of 1kb junk files). There's no universal way of extracting BIN files since they're related to a specific software that reads them, correct? Can anyone point me in the right direction, if this has been explored? Thank you.

Here's what my folder look like.

Try uploading the 2 files generated by this script when launched on AC3DATA.BIN:

Code:

# Armored Core 3 AC3DATA.BIN
math BASE_OFF = 0x10000
do
    get OFFSET long
    get SIZE long
    if SIZE != 0
        math OFFSET * 0x800
        math SIZE   * 0x800
        math OFFSET   BASE_OFF
        log "" OFFSET SIZE
    endif
    savepos TMP
while TMP != BASE_OFF

Can't analyze much due to the available small samples but at least the first extracted file is a sort of archive, for sure the last one isn't an archive so just dump and check what you can do.
There are no filenames either.

That produced a lot of results! Here's a spreadsheet with what popped out. I'm guessing the numerous .DAT files are textures. .VAP are probably SFX? Or maybe those are the textures. I'll look through the rest in the meantime. Let me know if you want something in particular uploaded. I think I have a tool for extracting .DAT files, but I don't remember if it's a Noesis script or some other tool I downloaded.

I tried running the DAT files through Noesis, but couldn't get anything out of them. So I guess I need a new script specifically for AC.
