HaloMods "Classic" Read-only Archive

i recently bought an xsata and put mods on halo 2 and it works fine so i told my friend ill put mods on his hard drive except when i extracted his map put the mods all his new maps wont appear any suggestions

this is the uberchassis

i have another question i know this is probably the noobiest question ever but when me and my friends try to race on a race track containment the warthogs wont move at all

Is there a way to make non-modders able to see my drivable uberchassis?
