the achievements are to reach certain floors in a dungeon and beat a boss at the end, the list is at the bottom of this link

The games have disappeared from my achievement list at the bottom they are xbox 360 games, some of them are backward compatible.

This would be a pretty good feature (i dont rhink it exists as of right now) but i would probably always be at the bottom of the list xD
