Extract files from Extended rom (on the PC)

[gaiden0000]

I've extracted the nk.nbf file from O2's upgrade Rom, and have then extracted the following files:

80040000-OS_0.nb
9b000000-Extension.nb
96000000-GSM_0.nb
91000000-SPL_1.nb
etc...

Now i know that the cab files i want exist within the 9b000000-Extension.nb file (as i am guessing that this is the Extended Rom). But i can't figure out how to extract the cab files (or all the files) from within in it.

I've searched around, and it's helped me get this far, but i can't seem to figure out how to get past this point. Can anyone tell me how to do this on my PC.
Many thanks.

I know someone in here can give me a quick answer to this one. All i want to do is get some cab files out of an O2 extended rom file on my computer (i can't use the extended rom unlocker on my pocket pc because i am currently using the crossbow OS, which doesn't include the O2 extended rom).

Thanks for any help.

If you are using orwell's wm6 your extended rom is probably still on your phone unless you wiped it off.

look for a software called winimage & load the extrom.nb file then u will see the contents.
