Beyond saving space, compression is a tool for preservation. As physical 3DS cartridges age and potentially face "bit rot" or circuit failure, creating highly compressed digital backups ensures these titles remain playable. Even though the 3DS officially supports up to 32 GB SD cards, the community has found ways to use cards up to 128 GB—provided they are formatted correctly—allowing for thousands of compressed titles to exist on a single device.
