I've just bought a 3DS for use on a long family trip next week. I would like to purchase Zelda: Ocarina of Time but I just know that I'm not going to get very far in that game without a strategy guide. I will not have access to the internet during this period so I was hoping I could load a plain-text or PDF walk-through onto my SD-Card and be able to quickly switch between the game and the guide as I'm playing. I'm just now getting acquainted to the 3DS UI and it isn't readily apparent to me if there is already a built in document reader to do this or if there is an 'app-store' in which I could locate a native 3DS program capable of doing what I need. Thanks!
