Opening GB files

Did your computer fail to open a GB file? We explain what GB files are and recommend software that we know can open or convert your GB files.

What is a GB file?

Files that contain the .gb file extension usually contain a ROM image of a game that is contained within a Game Boy game cartridge. The Game Boy is a portable gaming device that was introduced by Nintendo in 1989.

The GB file holds an exact copy of the data from the game cartridge of an associated Game Boy game. The GB file is stored in a read-only ROM format. This file can be used to play the associated game on a Mac or PC. In order to play the game, however, the user must have the proper emulation software installed on his or her hard drive.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
