Nintendo World Championships 1990 (USA) ROM

This is actually the rarest NES game on the planet, how we even got a ROM of it here is a marvel of modern science. Only a few where handed out to contestents during a competition in the 1990's and they had a unique feature on the top left handle that had buttons to change the paramaters of the game.
It came in 2 versions, the gray one and the 1 gold cartredge much like the LoZ, only 1 single gold cartredge was ever made for this game.

Please don't write game descriptions without getting your facts straight. The above statement about the number of gold cards is false they gave them away for division winners and in the Nintendo power magazine. So the number of gray cards is 90 and gold is 26 that makes 116 in all.
