'Yes, you can lock on other From Software games onto the Dark Souls cartridge. While Demon's Souls is an obvious choice (and unlocks the hidden world which everybody thought was gonna be DLC), King's Field IV works as well, allowing you to transfer your Dark Souls character into the game. Sadly, ]]game:kings_field_series|King's Field I-III]] don't. Instead, you are greeted by a scrolling sign that says とんでもない!, the Maiden in Black wagging her finger at you, and a series of numbers. Nobody has any idea what the numbers mean yet.'
