I picked up on of those 208 games in one cards, and I'm able to add and remove DS games. I don't have to mod my 3ds. I really want to play Zelda Four Swords Anniversary that was a DSI exclusive. It was removed long ago from the eshop. I found the .dsi file, but when I start the game it just goes to a white screen. Everything else is working great. Has anyone had experience with this and know of a fix?
