HaloMods "Classic" Read-only Archive

I am a newb...That has done nmpcxe and such...but i am having trouble installing descension


i have dl'd this and i am trying to get it to work...I dont have a big hard drive ( i have stock) so i dont have much room to play with 3 gbs... So what are the essential files that must be copied to a games folder so that halo 2 will play so i can use descension..and not other halo 2 maps..

Can i transfer them from my disk without using dvd2xbox by just saving the "d" drive files to my computer then uploading them to my "e:/games/halo2" folder

Currently i have transfered
--all bink files except credits
--default.xbe
--made a map folder put "descension" in it and the "fonts" folder
--THe whole media folder
--Dashupdate.xbe
--update.xbe
--downloader.xbe


I tried loading my smaller version of halo (no sp or mp levels except decension) and it said i have a bad disc

??????????????
What do i do? Any help would be greatly appreciated

You need to add it to your Main Menu.map

how do i do that?

thanks
