Coinheaven from here runs this site. PM him with the carts you'd like to get made from his site and he'll get them done for you at a good price!

Here's an example of his work: http://www.nintendoage.com/forum/...

Just got them from him last week!

Hope this helps you out!

How about a Mario Kart cart for the NES?

Honestly why bother?

When you could just play this instead: http://www.thenesdump.com/screen%20shot%20pages/Pirates/Kart...

Seriously though mario cart on the nes would be sweet although I haven't hear of one that exists,,,

Haha true. How weird is that? It looks like it plays as bad as my NES Street Fighter 2 cart.
