Just a heads up do not update your 3DS to the latest firmware. The latest firmware on the nintendo 3DS uses new protection and verification procedures to check if your cart is legit or not the new firmware has disabled the action replay dsi as well on the device so don't update or buy 2 3DS's one you can update and one you don't
There is no new 3DS firmware, the latest one is 3.0.0-6. Also, no 3DS firmware has been cracked yet. Some flashcard teams have found a way to circumvent the security measures, but this isn't a 'crack' or 'hack' or what have you.
All I meant was, there is a fix so you can still boot your DSI games on your 3DS with your flahs cart
New 3DS firmware? where ? as far as i know, the latest 3DS firmware is V3.0.0-6 and actually nearly most of the flashcards (acekard 2i, DStwo, r4i gold ) all support the latest firmware. so feel free to update. Just note, update your flashcard first before you update your 3SD console.
