HaloMods "Classic" Read-only Archive

this is probably a stupid question, but i was wondering how do you add stuff to the sky, like the invasion mod for coagulation has ships flying throughout the sky? do u have to take a sky from single player that has that?, or can u add stuff like that to any sky? im trying to get somthing like that ...

can someone plz tell me where to find a resigning program that signs the original signature to the modded maps (new maps)? encryptomatic does not work, when i ftp the maps back to the xbox, i still fail to load the maps
