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. 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 always strongly urge all of our customers to use the latest and newest firmware and to install the newest versions as they are released. 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. You'll never have to pay again to update your R4 3DS card or any other version of the R4 that we offer. And we also have lifetime updates on all firmware upgrades.

The firmware is free to download and use. 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. 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. You can think of it as the bootloader or menu system for your ds card. Without the firmware files, your r4 will not be recognized when you insert it into your DS, DSi or Nintendo 3DS system. The Firmware (or Kernel as it is more commonly called) is the heart and soul of the R4 3DS. Latest Update: August 10th, 2021 - All R4 3DS Cards Now Support The latest 11.15.0 E/U/J 3DS, 3DS XL and 2DS and NEW 3DS update. All of our cards are always updated to ensure that support even the latest system updates and continue to work and provide all of the features and functions you would expect from the R4 3DS card you own. Here you will find all of the latest firmware files for all of the different models of the R4 3DS Cards.
