XLaunchNewGame equivalent

[rene-hinterland]

We want to launch a new application and on xbox we can use XLaunchNewGame, but it's missing in the SDK.

What's the right approach here. Should we still be using XLaunchNewGame or should we just launch the other application using regular win32 processes?

I've tried adding a mapping for XLaunchNewGame, but it just seems to close the game and do nothing else
