Add More Storage with External USB Hard Drive (USB-Host) Mod for SNES Classic Mini (Old)

This is useful because many consoles like the Playstation 1, N64, MAME, or NeoGeo have large game files that can fill up the internal memory of the SNES Classic quickly. Now you can add all of the games you want and run them from an external USB drive. Follow our USB-Host tutorial to get started!
