2. Even with SDXC how can it hold more than a few games
3. How are we going to select games
4. They only showed evidence of it working with one game
Those questions are easy since there is no exploit which runs 3DS mode homebrew on the 3DS...
1. It will hold 1 game at a time in accordance to what this does (loading Splinter Cell on the 3DS home menu, not from a homebrew loader)...think of the first GBA carts...
2. You select the game by reflashing the cart by a USB port from a computer...think of the first GBA carts...
3. Crown3DS showed only a
questionable video. If they wanted everyone to believe them they should have shown a video of running, for example, the Splinter Cell game and then reflashing the cart through a computer and loading a different game.
Their use of Engrish sort of makes me want to believe they are legit, since there is usually a lot of Engrish on flash cart websites, but they're not really showing judgable evidence whether or not it is either real or fake.
