NES Global Problems


Problems that may occur with any NES title on Dolphin are listed below.

DirectX with NES Games

Most NES games suffer strange graphical issues when using the DirectX backend with some graphics drivers; notably NVIDIA. This is a driver bug.

As of 5.0-4869, the D3D driver bugs can be worked around by setting Ubershaders to Exclusive/Synchronous (Ubershaders). It's unknown what exactly is going on with the driver that's causing Exclusive Ubershaders/Synchronous (Ubershaders) to work properly.

This seems to have been rectified at some point, though it's unclear what resolved it.


This title does not have any additional game-specific problems.


This title does not need non-default settings to run properly.
