R4i-B9S flashcard FAQ

  • Q: Can Nintendo patch this?
  • A: Nope! Not without a new hardware revision.
  • Q: My flashcard is blocked by my firmware! Can I still use R4i-B9S card?
  • A: Yes! The flashcard blacklist is not enabled on the bootrom.
  • Q: Why can’t this work with other flashcard?
  • A: The installation requires you to flash NTRBoot to the flashcard’s nand. Not all flashcards have this!
  • Q: Can you make sure it works?
  • A: Yes, we are the manufacturer, and we know best what the flash card should be done.
  • Q: Can I unbrick from a brick?
  • A: Considering the card has access to the bootrom, most likely yes! This can potentially unbrick any brick (except MCU), unless you’ve taken a knife to the motherboard.
  • Q: Does this work on the New Nintendo 2DS XL?
  • A: Yes. Perfect support for 3DS(XL)/NEW 3DS(XL)/2DS/NEW 2DS(XL)
  • Q: Can I do this with a 8GB (or smaller) SD card?
  • A: Yes!
  • Q: Can I use a 128GB (or larger) SD card?
  • A: Yes, but some users have reported slowdowns when using such large sizes. Note that you cannot format the card with exFAT; you need to format it with FAT32.
