HaloMods "Classic" Read-only Archive

I just recently soft modded xbox, so I could save the maps from my xbox to my PC to edit it, and well I found spots where I could change what the battle rifle and rockets would do. Anyways I clicked save changes.. and tried to upload the warlock.map back to my xbox inplace of the old one, and the map wouldnt load..

Anyways Im asking for help on editiing what weapons do, and help on how to save and upload it back to my xbox correctly.

EDIT: I am using DotHALO btw..

This Should be in Halo 2 modding.

EDIT: If you want to mod warloc or other DLC you have to add them to ur mainmenu.map otherwise it wont work
