[PC] Paraworld (*.gsf)

Post by Kharg »

Can someone please help me to extract files from this format?
These files should contain .max or .3ds files but I'm not so sure...
Here some samples, if you need more just ask!
(Grazie in anticipo Luigi! :) )

I see no file table in that archive, no information about offset, size and names of the files.
Maybe there is a separate index file?

Well, the information about file names should be in the head of the file, maybe long with the block sizes of the parts.
We have already tried to decode this format but with just little success
here's an example
https://mega.co.nz/#!LsJ3XSyb!YfPrjWabS ... pnhpS5WOlo icewaste_animals gsf

https://mega.co.nz/#!b0g1FSxC!fUQA22f_1 ... -wC2mne9FY almost-decoded gsf


C Code of the tool we have made
https://mega.co.nz/#!fxx0jDyB!q4ozhdg42 ... BZAV1YL2V0

it looks like that the files in the gsf are zlib compressed likely...

About the index file there is a txt which contains the "classes info" which is the only thing similar to a index file

Icewaste animals classes file
https://mega.co.nz/#!a1B1xbDB!00491G06M ... 2ZLoKDYRBs

Another gsf + classes file

Please we really need help, we are the only team which is keeping this game alive :cry:

Maybe they are resources.
Anyway I don't see a way to extract data with quickbms and I don't even know where are the archived files because there are no known file formats.
