Digital archivists use region-free ISOs to ensure that rare software prototypes aren't lost to "bit rot" or the physical degradation of old disks.

In gaming, "region-free" means the software bypasses the digital locks typically placed on hardware from specific regions, such as North America, Europe, or Japan.

By making the ISO region-free, it becomes accessible to a global audience, regardless of whether they own a console from the original region of the prototype's development.
