I know you are famous

, and am in no way saying you don't know what you are talking about here....so please don't take it that way.
Looking at the Klov museum listing, there are only GT, Underground, and Carbon in arcade form. Those three are all I have ever seen in the arcade cabinets here in the states, and all I have seen at my job's warehouse.
I found one image and reference to it online through google, but it said it was released 2004, and GT was released 2003. Do you have any pics or anything else pointing to this?
I will also happily check the discs we have for versions at my job too, just to see if there are backup discs anywhere.
