Nintendo 3DS in-game menu: notes, friends and more explained

[cwstjdenobs]

IIRC in game menu music support is trademarked by Microsoft.

Seriously?

It's true!1

I'm interested as to how the friend system works.

I didn't know my 360 could do that. But I've only played 2 games on it, lol. How does it deal with the music and games audio interfering with each other? For that one reason alone I could see it been better implemented in the game rather than through the consoles OS itself.

Or, Europe doesn't have software patents and the 3DS is region locked, couldn't we get features blocked by patents in the rest of the world?
