Why do you need the R4 3DS Firmware?  

The Firmware (or Kernel as it is more commonly called) is the heart and soul of the R4 3DS.  Without the firmware files, your r4 will not be recognized when you insert it in to your DS, DSi or Nintendo 3DS system.  You can think of it as the boot loader, or menu system for your ds card.  In fact, one of the biggest reasons why many have issues using their cards when they first receive them is because they have not yet installed / copied over the firmware files to their micro SD Card.  The R4 DS firmware is what will install the menu, and allow you to load all of the games, applications and software you have on your r4.  

The firmware is free to download and use.  And we also have lifetime updates on all firmware upgrades.  You'll never have to pay again to update your R4 3DS card or any other version of the R4 that we offer.  Should a new update come out because we have discovered some incompatibility, or added some new features, they will be announced here and available for you to download at no cost at all.  We always strongly urge all of our customers to use the latest and newest firmware and to install the newest versions as they are released.  This helps prevent any issues with console updates that may temporarily not recognize the R4 3DS, as the new firmware once again enables all of the features we've all come to love about our ds homebrew cards.

We recommend you download 7-Zip - the open source freeware archival tool that allows you to uncompress zip, 7z, and RAR files - free!  All of the firmware comes in one of these archive formats.  Get it from te 7-Zip site

If you have the R4i Gold 3DS or R4 3DS Card, and your Nintendo 3DS systems is on the 3.0.0-5 or 3.0.-6 upate, then you will need to download the upgrade pack here and use a Nintendo DS or DS Lite consoles to be able to update it.
