What is an R4 Acekard adapter, and why should I get one?

The Acekard 2i (also known as the R4 Acekard, and Ak2i) was a card that was a latecomer to the Nintendo DSi homebrew scene but has built a strong reputation on solid performance and one of the quickest response developers in the industry.  Few other teams are able to match the speed that the Acekard team releases new updates and fixes. The Acekard 2i has experienced excellent longevity due to the upgradeable nature of the firmware via the menu .nds method.  The Acekard 2i is a unique product from a dedicated team and has never been a clone of another card.  A few clones of the Acekard have popped up, notably from as opposed to the genuine website

The Acekard 2i is also in a unique position where the unofficial alternate menu software became more popular then the official menu software while it was still supported.  This software is the AKAIO or Acekard All-in-One loader that was developed by a third party for the Acekard 2i, but not of the Acekard team.  The Acekard team has now adopted AKAIO as their preferred menu software.  The Acekard 2i coupled with AKAIO is one of the fastest loading cards out there with exceptional compatibility due to their frequent updates.

The R4 Acekard type allows users to expand a lot of usage of the DS console, whether that is the old Nintendo DS, DS Lite, DSi, DSi XL, or 3DS console with the standard SLOT-1 use(the standard Nintendo DS games slot). As well as playing games, the Acekard 2i also enables playing music, converted videos, and pictures using the Moonshell hombrew application.

A micro SD memory slot is on the top of the Acekard 2i.  The Acekard 2i uses a spring clip style slot so some care is needed to make sure that you don’t damage it.  The Acekard 2i supports all SDHC sizes from under 2GB to 32GB.

How does an Ak2i card work?

The Acekard 2i allows access to a micro sd card storage and runs custom firmware on top of the DS menu.  No data is modified or left behind on your console itself, the Acekard 2i handles it all.  The menu software file as well as all games and content are stored on that micro sd card.  Save game files are also created on that micro sd card which makes it easy to back them up.  As well as turning your DS into a personal media player, the Acekard 2i will also allow you to carry your entire games library on one single cartridge so that you don’t risk losing your valuable retail cartridges.  Better to lose/damage one 25$ Acekard 2i then 250$ worth of games.

  • As for the question Which Micro SD Card for my DSi Acekard? – we’d recommend using a 2GB or 4GB card for the more casual users who mainly play some games and applications on their Acekard adapter, and the 8GB or 16GB micro SD card for those that have a lot of audio and video files, or a very large games collection.

    Now that you have everything you need to set up your new R4 Acekard 2i, you need to download the latest firmware. The manufacturers are always updating the software, and therefore it’s useful to periodically check in to see if there are any updated Acekard firmware downloads available.  The official site for the Acekard 2i card is located at– Once you have downloaded the software, save the ZIP file to somewhere on your computer (usually the desktop is the most visible place). Right click the ZIP file and choose the ‘Extract All’ option.  You should then see the files and folders inside the ZIP file, which is what we’ll be transferring over to your micro SD card in the next step.
  • STEP 4 – Setting up your micro SD card for use with your Acekard 2i

Your micro SD card’s directory should now look like the image below (note: AKAIO version at the time of writing used in the screenshot below, later firmware versions may look a bit different but this is fine).

    And you are now ready to go. Simply add games and multimedia files as you wish onto the micro SD card from this point, then right click on the drive from My Computer and choose “Safely Remove”.You can now place the micro SD card inside the R4 Acekard, and boot it up with your Nintendo console!

Acekard 2i Frequently Asked Questions

Some of the more commonly asked questions about the Acekard 2i card will go here. This list may grow over time.

  • What is the biggest micro SD memory card size I can use with my R4 Acekard adapter?
    The largest theoretical capacity the Acekard 2i  can accept is 32GB, although stores very rarely sell memory this big because it’s quite expensive. 8GB tends to be the option most people go for, with 16GB for those with particularly large numbers of games and multimedia they want to use with their Acekard.
  • What consoles is the Acekard 2i compatible with?
    The Acekard 2i model ds adapter is compatible with the original Nintendo DS, DS Lite, DSi, DSi XL, and 3DS consoles. However, you must make sure you never  update your console’s firmware (known as “System Update” in the settings of your console) because these updates often cause R4 cards to stop working. You should always wait for the Acekard team to release patches to make them compatible with new Nintendo updates, before updating your console.  You might be prompted to update your DS card by going to the DSiWare store or DSiBrowser, don’t do it.
  • I have updated my Nintendo console to the latest firmware and now my Acekard doesn’t work. What can I do?
    Unfortunately it is impossible to reverse a Nintendo console update. Check the official manufacturer’s website to see if there is a patch / fix out for the console update you have just applied. If there is, you can download and update the console (although you’ll need to use a DS Lite / pre-patch DSi or 3DS to apply the patch, you can’t use the same console to apply it). Otherwise, you must be patient and wait until a fix comes out (this typically takes anything from a week to two months), or buy a different card that is compatible. See our Where to Buy R4 page for stores that have other cards for sale that could be compatible with the latest Nintendo console firmwares.
