yeah, my tailored Wii and gamecube collection fits on a 128gb sd card. Granted i do have Wii Virtual Console games on my Wii U along with the Zelda HD remakes, but that's still less then 250gb easilyYou could also consider reducing the collection, especially since there are a lot of shovelware on wii specifically...but I guess that is part of the experience
