I am trying to mod my hl2 disc to integrate the maps of HL2 into Portal and modify the script that loads the maps in portal so I wont have to use a console screen (pretty hard on a 360). I also might want to modify the title screen to show only portal and maybe add some custom maps to the game.
I have extracted the contents of the Half Life 2 Orange Box disc to a directory on my hard drive. The directory structure of the disc has each individual game in a separate folder (eg EP2, HL2, Portal etc...). In the root I have found a file called Default.xex which I am sure is like the .xbe files for the regular Xbox - is there an editor for this file type? Also under almost each folder is a file labeled zip0.360.zip but Winrar doesn't read it properly. I am assuming that this is the file I need to unzip and modify and repack in order to modify significant content in the game (like the game 'load map' script). Is there a utility that will allow me to unzip these files and then repack them when I am done?
So to Recap:
1) I need a .xex editor. Is there one available?
2) I need an xbox360 zip utility. Is there one available?
Thanks in advance.
