An script to open OSPC file from Darksiders?

Post by SeemosYantra »

I'm trying to open the contents of the "streams.ospc" file on the Darksiders game folder for PC. Unfortunatelly, I was unable to find any script capable of openning that file and I tried to use the script used to open .oppc files, but it didn't work (as it would be expected). If anybody can help with this, I would be most thankfull.

I'm attaching here an screenshot of the Hex Editor result because the file is like 800Mb. Hope it helps.

The FSB4 magic at the beginning of the file means that there is no archive header since the first file from offset 0 is a small FSB archive.
Maybe the information are in the footer but would be necessary a sample or a filecutted sample generated with http://aluigi.org/bms/filecutter.bms
Last solution is just using fsbext -o -1 that will automatically scan the "streams.ospc" archive extracting all the FSB files:

Regarding oppc it seems really very strange that the script didn't work because it has been tested with various DS versions.
Maybe upload the filecutted samples of this type of file too.

Thank you so much! Using fsbext did the trick as it unpacked all the files in MP3 format, which is exactly what I wanted.
