Xbox 360 Avatar Games?

Hi. Quick question. Shame on my bloodline if it's been answered before, but, on the Xbox 360, there was a collection of games revolving around the Xbox 360 Avatars like Castle Miner Z, A Kingdom for Keflings & various titles that aren't available on the website. Is it not possible to emulate the avatar stuff? Do those games need to be a solid disk to emulate it? Sorry if this question seems dumb, even though the answer seems obvious I think it's better to have it written in stone than blindly assumed on my end. Cheers!
