PBP Unpacker is the only program i use for editing EBOOT's. Although it contains no command-line options.
The documentation does describe the HEX offsets of each embedded file though. So that has helped, obviously EBOOT's do not compress any data.
OK, well from this software i create i'll probably create a command-line based EBOOT injector too seeing as how one doesnt exist :P
Thanks for your help once again birdman
