You need to find someone with a ds / ds lite. Put the updated card into ds / ds lite Tap third icon and you should see two options , config and upgrade Press upgrade and it will update your card (in approx 4-5 mins) Put card into your dsi and miami nights 3d icon should show! Your dsi should now work..
