Wanted: DS Kiosk Demo Carts

I know this may be a far reach, but I am after most any DS retail demo cart. I am not looking for a copy of the Metroid pack-in cart that came with the first wave of systems.

I currently HAVE the following:
--------------------------------------------------
Download Station Volume 1,2,3
Nintendogs Download/Relay Version

Ones that I DON'T have and would be interested in are:
--------------------------------------------------------------------------------------
WarioWare Touched
Mario Kart
Castlevania: DoS
Download Station Volume 4
Big Brain Acadamy
Any Japanese or European demo cart
Any others not already listed

PM me if you have any that you might be willing to part with and what you want for it.

Thanks

I will try for a couple more days. Daily Bump
