Hi,

If I only play offline is there a way to get hold of
- Downloadable Game Content
- Game Updates
- Arcade games

like I do with normal backups

Your not talking about piracy now are you? ,

Piracy isnt allowed here for obvious reasons so try another forum.

I think he means getting patches and title updates if you didn't have an internet connection.

I do not believe there is a way, and because most people have internet access, there will never be a way.

you can buy game dlc in stores over here.

Don't answer if you don't have a proper answer.

Now on topic,
Yes, that is possible. There are title updates packages floating on the internet, connect your HDD trough a kit or trough a simple sata connection with your computer, transfer the files inside the package to the HDD (the package contains instructions) with Xplorer360 and boom! You don't have to worry, Title updates are not constrained to one's gamertag.

You cannot transfer your XBL Arcade games, unless you have Jtagged your console.
