In Mega Man 4 for a year the city has been quiet, but a new robotic terror has gripped the city! That scheming scientist, Dr. Cossack has arrived in town with eight new metal maniacs who are bigger and badder than anything Dr. Wily dreamed of. It's going to be a cybernetic showdown as the streets of the city erupt with the sizzling sounds of molten metal! Armed with the new Mega Buster, Mega Man runs, jumps and dodges his way through mazes of metallic munchkins on his way to the Siberian citadel of Dr. Cossack for the final cataclysmic clash!

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.

NVIDIA Title Corruption

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.

Problems

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

Configuration
