So I have an ipod classic 80 GB, usually they don't show up outside of itunes, but there's apps out there that modifies it a little so you access it and insert files, (I noticed this when I tried the yamipod player). And voila, a 80 GB USB! You can keep Dolphin and your games in it, then plug it in anywhere and play, no lag or anything caused by the game being on the ipod. only problem is that it's FAT32, so wii games that can't be compressed to under 4GB can't be used. Now if you happened to visit a friend with a super computer, maybe he'd let you enjoy some Hyrule Field in fullspeed
