HaloMods "Classic" Read-only Archive

I see that people release patches so you don't have the Auto Update to load the new maps... However, I tried it before and could not system link them. Do I have to have two modded Xboxes with same main menu? Or did I do something wrong when creating the main menu?

If you are talking about the patch that puts the TDATA maps on your mainmenu, then yes, both Xboxs have to have the maps on their mainmenu.
