Have a DS flashcard?
If you have a DS flashcard that was able to be used on a 3DS at some point before Nintendo blocked it, you may be able to use it again! Note: The following method will not work for old DS flashcards that were blocked since the release of the original 3DS.
Open the
Gateway Ultra download and go into the "Blue Card Fix" folder.
There will be a bluecardfix.cia inside; put it on your 3DS sd card.
Insert your SD back into your 3DS.
On your 3DS:
- Sysnand and open cia installer (fbi or devmenu2x only other cia installers will not work) .
- if fbi Press L to change Destination to Nand.
- Select bluecardfix.cia and press A to install it.
- Choose to overwrite the title if it prompts you.
- Once done, exit cia installer.
You should now able to use your DS flashcard on your 3DS.
Things to note:
- If your DS flashcard still doesn't work, then it will probably never work on your 3DS.
- You can use your DS flashcard in any mode (Sysnand, RxMode, Devmode), but exiting the card will bring you back to regular sysnand.
- Running a DS flashcard will remove your MSET exploit if you have one (see the next section).
- You can use a DS flashcard to easily install the MSET exploit (see the next section).
