Hi,
who knows how to remove the nude patch from Dead or Alive Xtreme Volleyball?

a buddy gave me a backuped (and nude patched) doa v-ball version and now i want to remove the Nude Patch.
i think i need an unpatched default.xbe and datadvd.afs. am i right?
i´ve got the game on Xbox hdd so i can replace the patched files.

who can help me?
am i right, that i need this two files?
and where can i find these (or the other needed) files?
