Flashing ntrboot (DSi)

Before proceeding, ensure you have read all of the information on ntrboot

This method requires temporary access to a Nintendo DSi that is compatible with your flashcart.

Note that more recent DSi versions have blocked access to some flashcarts. This leaves them unable to launch the flasher .nds file on newer versions. The ntrboot compatible flashcarts are able to launch .nds files under the following versions:

• R4i Gold 3DS RTS : All Versions <= 1.4.5
• Acekard 2i : All Versions <= 1.4.4

Note that in some rare circumstances, it may be possible for the flashing process to brick a counterfeit flashcart and render it permanently unusable. This is unlikely, but nevertheless only original listed flashcarts are supported. To reduce the chance of receiving a counterfeit card, it is recommended that you use a reputable site to buy your flashcart (such as NDS Card)
