Why Can't I Edit Screenpacks

So I downloaded the Marvel vs. DC Mugen Multiverse screenpack, and it's amazing, don't get me wrong. But when I open the system.def file in Fighter Factory so I can poke around and see everything, there's no sprites, and also no way to edit the sound (which I'm also having trouble doing with other screenpacks). Why can't I?

first: not use def file in Fighter Factory 3, use the click "sprites" and open system.sff that screenpack files!! you see the sprites!! and created new folder....now you got and click in pcx and saves all group in the new folder...put a easy name the pic like 1.....
music: go to system.def file and you got this or similar:
