HaloMods "Classic" Read-only Archive

Is there a way for me to copy my downloadable content (perferably the 2 halo 2 free maps) and copy them into my friends xbox. We both have modded xbox's, and I have not had much time to look into this myself, but is it possible. You do not have to worry about me transfering stuff that everyone has to pay for since I have not paid for the 2 other maps And also, is there a file that I can copy into his so that he will have the update on the game (the patch that was released).
If that is not possible, is there a way to transfer game saves (not whole games, just i guess you can say profiles and such) from my xbox to my friends.
I am sorry if this goes against the rules, but I checked and there was nothing about this on there. I am only asking this because I can not get his xbox to my house and he does not have xbl. If he did, then I would just be asking about the game saves/profiles.
Thanks

well you can directly tranfer dlc from 1 xbox to another without it getiing corrupted, But there are new map pack installers out there like the AWSK 1 that install the new maps just like live would,but i pretty sure im not allowed to talk about where to get it...

Thank you shade. Yeah, I do not think that you can let me know, but I think I just found a site anyways. When I found it, it reminded me of this topic so I that's why I came back. So I guess I'll try the mappack installer instead of ftp-ing the maps then. Thanks
