Challenger was originally planned as a port of the ZX Spectrum game Stop the Express, though Stop the Express only contained the first train level, and 3 levels were added for the release of Challenger. The game's title screen displays the slogan "Realtime Action Adventure." The game is uniquely constructed, where the levels consist of a side-scrolling platform game, a top-view scrolling shooting game, and a fixed-screen action game. The game was also unique for its 100-screen map, which was extensive for its time.

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.
