No More Heroes Red Zone Edition on PS3 included a model viewer where you could ogle at a butt naked Silvia.

There's almost no coverage of this anywhere of this on the web and HD footage is practically non-existent from what I've found. I wonder if there's a way to emulate it in full detail since apparently the model viewer or some of its content was DLC.
