I have an XBox 360 that hasn't been connected to a network for about three years. I finally got around to hooking it up today. It downloaded a bunch of updates and I created an XBox Live account (just a standard one, not Gold).
However, I can't seem to get it to update any of the games. As in, there's no notification that an update is available, even after starting a game. I know they're not updated because, for example, the radios in Portal don't "receive transmissions" ;)
The network setup is a little non-standard: I configured my laptop to bridge the XBox ethernet to the household wireless. But since it downloaded the system updates and confirmed the XBox Live account, I figure that connectivity is not the problem. If it matters, the dashboard version is 2.0.14719.0
How do I prompt the XBox to update my games? How do I tell if a particular game has been updated?
