Just seen this on ebay -
http://www.ebay.co.uk/itm/SEGA-Dreamcast-Shenmue-Prototype-Early-US-version-with-full-DEBUG-menus-/262050942421?hash=item3d03740dd5
Anyone even know this existed? I really wanna try it out...hopefully if someone wins it from here, they could upload the image files for us all to try ?
