A Boy and His Blob: Trouble on Blobolonia is a platform-puzzle game that puts the player in control of the boy; its gameplay revolves around feeding his blob companion different flavored jelly beans to change its shape into various tools in order to overcome obstacles and traverse the game's world. A Boy and His Blob was designed and programmed by David Crane. Licensed by Nintendo in the summer of 1989, development began and was completed in an intense six-week period. Crane has described the game's overall concept of a boy accompanied by a morphing blob as unconventional and wanted to try his own hand at implementing useful tools for the player.

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.
