The NES Dragon Warrior cover here says it's formatted for the universal case, but it's actually too big.
It's just a little format error....
1. Open it in photoshop....
2. Go to -> Image -> Image size
3. In the "document size" part of the window change the dpi to 300
4. In the "pixel dimensions" part of the part of the window change the pixel back to 3366 x 2100
5. Click OK -> Finished
Don't worry there's almost no qual lost here because you just correct the size of the picture....
