We are sorry you are having an issue with your physical cartridge. Here are solutions to the most common cart problems:
Gray screen or blinking power button
These old machines were finicky even when they were new. Try taking out the cart, and putting it back in. Then turn power on.
Hey! I am still getting a Gray Screen or Blinking Power Button!?
Are you outside of the USA? It is possible you need to switch the region. Good news... our carts are multi-region. All you need to do to change the region iis stick in the cart, turn it on, and hit the reset button 4 times. There are also instructions to do this on the back of the cart.
It is not working with my 3rd Party created NES Hardware
OK. Let's make sure your device is compatible. Dungeons & DoomKnights will run on any real NES hardware. Our game uses Mapper 30. But some new systems like the Hyperkin Retron 5 use emulation which does not support Mapper 30. I posted a list of known compatible hardware on the official Dungeons & DoomKnights website. Check to see if your hardware is compatible, and if not, check the vendors site to see if there is a patch/firmware upgrade to make it compatible.
