Added this to my Mega Drive collection. It's a German only "Vorfuhrmodul", it's a a NFS demo/sample of Virtua Racing that was used for trade shows and shops, only a few are known to exist, I had one and sold it a few years ago and I am made up to find another. It may look like a bootleg but it's not!
As some of you may know Sega's European HQ was in Germany so no surprise an oddity like this came out of there, you will notice that the cart is the standard size and has no heat shield like the larger final cart design, the game appears to be the final version but the cart is glued closed so I can't check the internal PCB or chips. Sega used a donor cart shell from another game and stuck a new paper label over it! (You can see that they then blanked out the edge of the existing label with a Sharpie, class

) Probably asked the intern to male these....
