1990 Gray Nintendo World Championship – REPLICA


Until further notice, promo codes will no longer be eligible for use on Nintendo World Championship gold and gray replica carts. Due to COVID-19, materials costs have risen. Please visit frequently for updates.

Buy it now and you will be hooked up with some serious nostalgia. Here’s what else comes with your gray NWC Replica/Repro cart:

(Please let us know which system you will be playing on in the order notes. We have a few versions of the game that will not work on the Retron HD.)
– A UV-protected case when it arrives
– A black Nintendo dust sleeve
– Clear-printed Nintendo World Championship labels which you can apply
– Another NWC label option which you can cut and apply just as the employees did with the gold versions given away in the Player’s Poll Contest from Nintendo Power Magazine
– A mini-sized replica version of the NWC “certificate of completion” that was given to the finalists at the 1990 NWC competition
– An Orange and Black DIP switch to discern this reproduction from the original

There are other NWC reproduction carts made by other companies, but ours is as high-quality and close to the original as it gets. It’s time you own a replica of one of the most revered video game competition compilations in the world.

FAST AND FREE shipping in the U.S. via USPS First Class Mail. We will ship within 1-2 business days and provide tracking info.
NO HASSLE RETURNS – All purchases come with our no questions asked 90-day return policy.


Here is the gray option of the 1990 Nintendo World Championship video game cartridge. Authentic-looking and pristine.
This cart makes for a great conversation piece and is perfect for friendly competition amongst fellow retro gamers, friends and family.

The backstory: Nintendo gave 90 gray cartridges as prizes to the finalists in the 1990 Nintendo World Championships. This makes the original cart not only a very hard game to come by, but ridiculously expensive to purchase. We are retro gamers to the core at 1UP Retro, and we feel that just because the actual competition cart is so incredibly rare, it doesn’t mean you have to be lucky or a millionaire to buy it. You can now own this amazing reproduction of a great piece of video game history for an affordable price.

– A fun and addictive time

– A tested and trusted NES reproduction
– Works on the original Nintendo system (may or may not work on Top-Loader depending on version) and fami-clones
(Please let us know which system you will be playing on in the order notes. We have a few versions of the game that will not work on the Retron HD.)
– NTSC compatibility
– Free standard shipping

– 100% satisfaction or your money back
– Your retro gaming friends will be jealous
– That it WILL NOT work on the Retron 5

NOTE: The sticker will not be on the cart when you receive your order. It will come with 2 different NWC sticker options and you may choose which one you would like to adhere.


The DIP Switch allows different times depending on position (on/off). All pins down/off will give you 5 minutes.
Pin 3 up/on is the common configuration for 00:06:21:00 (which I believe is actually more around six minutes and 15 seconds).

This cart is compatible with original hardware and all fami-clone systems including the Retron 5.

As diehard retro gamers, 1UP Retro thanks you for keeping retro video gaming alive and remembering your gaming roots!
