DB3150 extraction

Hi.

I need to play (modify) camdriver and acoustic drivers for c702. The only problem is i am unable to extract those files from oryginal. Sefstool4 says that it cannot find something in the starting adres of the file (converted to raw of course). read3150 works great but extracts only TPA folder fully (IFS is empty). I've read somewhere it could be done with WinHex but have no idea how. Any clues.

PS: yes i do have SEToolBox so please do not write db3150 is not hackable ;)
