hey martin,
In the other post i have put the picture of the 6 n64 proto's i had.
I included a nice close up of the castlevania proto.
All the n64 proto's are from dutch origin ( i found them all in a second hand shop)
I traded them with castlevania forever (niels)for a nwc grey.
He kept the castlevania proto and the mystical ninja 2,the rest got sold.
I still have a turok NFR cart.
Just made some pictures of the cart and found out it was pal

Thought they where all usa or international
But this 1 is pal because it has french,english and german on the back of the cart.
Anyway: most NFR carts have the same front as the original cart except it says NFR and are for the n64 kiosk in the shop.
Also the n64 nfr are the same as the 'normal versions'
BUT turok 2 NFR is different: it gives a warning at the beginning of the game that its a demo and you can choose levels and you have all weapons at the beginning at the game.
