If you have already flashed ntrboot to your flashcart or your flashcart comes pre-flashed with ntrboot, you can skip to [Installing boot9strap (ntrboot)](installing-boot9strap-(ntrboot)) for instructions on how to use it.
Installing boot9strap with ntrboot requires a compatible NDS / DSi flashcart to flash ntrboot to. Note that some of these flashcarts are sold pre-flashed with ntrboot.
While the ntrboot exploit works independently of system version, the ntrboot flasher (which installs the exploit to the cart) is not. This means that, depending on the versions and devices supported by your flashcart, only certain methods may be available to you.
Note that carts with a "Time Bomb" will no longer be able to launch `.nds` files when they detect that the system clock has passed a date determined by the flashcart firmware. One method to bypass this is to set the system clock to an earlier date.

| [**DSTT**](http://www.nds-card.com/ProShow.asp?ProID=157) | $9.99 | No | None | None | Only models with [certain flash chips](https://gist.github.com/Hikari-chin/6b48f1bb8dd15136403c15c39fafdb42) are compatible with ntrboot. |
| **Ace3DS X** | | No | <= 11.6.0 | <= 1.4.5 | **Comes pre-flashed with ntrboot** (external switch to switch between ntrboot ("3DS") and NDS modes); do not manually flash with ntrboot. |
Ensure your flashcart is able to launch `.nds` files on your device before beginning. Some flashcarts may require firmware or "kernel" files to be copied to the flashcart SD card. Consult your specific flashcart's instructions for more information.
The usage of this exploit, regardless of flashing method, requires access to a small magnet if the target device is of a folding style (any 3DS family system that is not the old 2DS with a sleep switch). This is because the exploit requires your device to enter sleep mode while still having access to the buttons.
To test if a magnet will work, hold it on or around the (A)(B)(X)(Y) buttons while the device is powered on to see if it triggers sleep mode. If it does, both displays will go black as long as the magnet is held in that spot.
Note that the flashcart will not be able to be used for its standard functions while the ntrboot exploit is installed on it (except for in the case of the Acekard 2i, which remains functional *on NDS and custom firmware 3DS systems only*). This means that, for most flashcarts, it will not even display on the home menu. Na końcu instrukcji instalacji ntrboot znajdują się opcjonalne kroki, aby usunąć go z flashcarta po zakończeniu.
Zauważ, że w niektórych rzadkich przypadkach proces wgrywania ntrboot na podrobiony flashcart może go **"zbrickować"** i permanentnie uszkodzić. Jest to mało prawdopodobne, ale jednak tylko wymienione oryginalne flashcart'y są obsługiwane. Aby zmniejszyć prawdopodobieństwo otrzymania podrobionego flashcarta, zaleca się korzystanie z renomowanej strony do ich kupowania (takiej jak [NDS Card](http://www.nds-card.com/))
Ta metoda wymaga tylko 3DS'a którego chcesz przerobić oraz kompatybilnego z ntrboot flashcarta. Ta metoda używa flashcarta aby uruchomić plik ntrboot flasher `.nds` na twoim 3DSie. Oznacza to, że twój flashcart musi obsługiwać uruchamianie plików `.nds` na twoim 3DSie. See the flashcart table above for more information.
This method requires temporary access to a second 3DS family device that is already running boot9strap. Dzięki tej metodzie flashcart nie musi obsługiwać wersji systemu żadnego 3DS'a. See the flashcart table above for more information.
This method requires temporary access to a Nintendo DS or Nintendo DS Lite that is compatible with your flashcart. This method uses the flashcart to run the ntrboot flasher `.nds` file on your NDS.
This method requires temporary access to a Nintendo DSi that is compatible with your flashcart. This method uses the flashcart to run the ntrboot flasher `.nds` file on your DSi.
