data.img | Ghost in the Shell: Stand Alone Complex (PSP)

Post by swosho »

Entirety of the game data is stored in a single data.img archive. Admittedly, I'm not versed in the game archives but so far I haven't seen a header like this one has.
I'd be infinitely grateful if someone could take a look at it.

The samples made with the filecutter script.

Quite complicated since it looks like a sort of custom ISO image or filesystem.

Now that you mention it... it is indeed appears to be laid out like an image of sorts. If nothing else, it looks like it should be relatively doable to utilise only the hex editor to dump and replace the audio and video files, at least with the downsampled ones.

Thank you for checking it out, and sorry I can't really contribute anything.

In case you or someone else would like to take a look at the full archive – here it is (709 MB).
