Updated the guide a little

Snapshots (game saves) are saved to the xbox hard drive image so just backup your hard drive image if you want to save your games and you access and manage them via settings menu.

update: after doing a little configuration the game doesn't boot. I think I messed something up in the settings. Probably selecting the wrong bios or something.

I will keep testing. If anyone knows what I did wrong please share your input.
