(adsbygoogle = window.adsbygoogle || []).push({}); How do I host Challenge lobbies On mw2??
I want to do this the old fashion way (with data transfer)

So Here are a Couple Questions...
1) What EXACTLY does data transfer copy?

2)DO I need to delete my FTP server?

3)Do I need to delete my Demos from PSN store?

4) Do I need to delete my old patches? RETAIL.

5) How Do I host them with the Map Packs....

6)Can I invite friends to the Challenge Lobby if Im using a patch blocker?
