Installing and updating


Download the latest AKAIO from the links section below. If you have the official firmware installed, delete the __ak2 (or__rpg) folder and the akmenu4.nds from your memory card. Then extract the downloaded compressed archive (using winRAR, etc) and move the included __aio folder and akmenu4.nds file to the root of your microSD card.

AK2 Loader

The official AK2 loaders can be used by AKAIO to load retail ROM dumps. This is an outdated method as the AKAIO loaders are currently more up-to-date and optimized more often, however, the option still remains for those who wish to make use of it. To install, the firmware file akmenu4.nds must be placed in the __aio/ak2loader/ directory. You can rename the official loader if you like (IE: ak4.11.nds, ak4.12.nds, etc). Renaming the loaders allows you to have multiple official loaders for use with AKAIO at any one time. To use the loader, select an .NDS file, and open up the file properties by pressing the Y button (or use the Start menu). Press Y again to bring up the .NDS options. You can now change the loader from AKAIO to an AK2 official loader

This option is for use with an AK2 only, and not the R.P.G. or AK2i

Cheat Databases

You can have multiple Cheat DB in your __aio/cheats directory, you are also able to name them for organizational purposes.

Updating via computer

The latest Cheat DB can be found at AKAIO can use CHEATS.XML, CHEAT.DAT, or USRCHEAT.DAT format. Simply download and place the file in the __aio/cheats directory.

Updating via Wi-Fi

Cheats can be updated via Wi-Fi in AKAIO. It requires the Wi-Fi to be set up in the DS firmware (by using a game that connects to Wi-Fi). The USRCHEAT.DAT update can then be found at Start > More > Wifi Update. AKAIO will then automatically download and uncompress the newest cheat database.

A nice feature of the Wi-Fi updater is the option to check "What's New" before deciding to update by setting Get WhatsNew.txt to Enable in the Wi-Fi Update window.

R.P.G. owners can update to the latest "savelist.bin" via Wi-Fi by selecting the "savelist.bin" button in the Wi-Fi Update options window


External icons are supported in AKAIO. They must be in BMP format at 32x32x15bpp. Naming conventions are described below. Mr.VatoLoco has compiled icons for the use with the AKAIO, you can find his post here

Per Extension Icons

Icons named with the extension of the file you wish to associate them with can be placed in the __aio/icons directory for global usage, or your skin's /icons directory for usage with just that skin (__aio/ui/Adv.Evo/icons) For example, to use a custom icon for all files with a "TXT" extension, your icon will be named "TXT.BMP."

Per File Icons

Specific icons can be assigned to specific files in AKAIO. Make a standard 32x32x15bpp BMP icon for the file which you wish to have a custom icon, and name it the exact name of the file, but with a .BMP extension. For example, for the file "Bob's Homebrew Game.nds", you'd have a BMP named "Bob's Homebrew Game.BMP."

Make sure to place the icons in the same directory as the file you're assigning them to.

Selecting the MicroSD and then choosing to view its properites will reveal the Disk Capacity, Used Space, and Free Space of the loaded media.

GBA Game

Selecting the GBA option will reveal that the user can use A to boot in GBA mode or L+A to boot in NDS (PassMe) mode.


A shortcut's properties selection displays the ROM icon and Internal text name as well as the fact that the file is a shortcut.


This selection displays the .NDS Icon, Internal Header (The three lines of text that come with each game), the.NDS Name, Last Change Date, File Size, Save Type, and Game Code. Button availability may be limited the NDS ROMs only, some features will not display with .NDS Homebrew files.

Cheats Button

Should you be using a .DAT file for cheats (by default, USRCHEAT.DAT is included) and the title you are viewing the information of has cheats, a "Cheats" button will be visible on the ROM Info Window as well. You can press the button or hit SELECT to access the cheat list. This button will not appear if you are using a .XML file for cheats.

Shortcut Button

A shortcut can be created for any .NDS file, .GBA file, or any Folder by pressing X on the Properties Window or clicking this button. A shortcut will then be displayed in your Root directory. You are able to have only one shortcut at a time, and using the option again on another file will replace the shortcut. You can remove a shortcut by selecting it and pressing X.

While in-game, cheats are enabled by default on loading. Press start+select+down to disable cheats. Start+select+up reenables them.

3in1 FAS1 Slot-2 Support

Thanks to the awesome support of users, started by Another World, EZ 3in1 units were donated to Normmatt and Smiths. With working units, progress was made on optimizing the 3in1 integration into the Acekard menu.

Settings: Start > More > 3in1/FAS1

  • Rumble level - Off/Low/Medium/High
  • NOR Mode - Auto/Always
  • Backup GBA save at startup - Disabled/Enabled
  • Prompt before Save/Load - Disabled/Enabled
  • GBA Universal sleep - Disable/Enabled (L+R+Start: Sleep and Select+Start: Wake up)

The NOR mode auto setting will send any GBA ROM less than 17MB to PSRAM, while the "always" setting will flash every GBA ROM to NOR. Prompt before Save/Load will prompt the user for a "Yes/No" response before loading or saving any GBA .SAV files. This is the recommend way to use your GBA expansion cart without loss of .SAV data.


FAS1 is a Homebrew written by Smiths based off of tftpds (by Sten Larsson and Gustav Munkby). It's for users of older FlashAdvance Pro Slot-2 cartridges who wish to flash programs to their kit from within the AKAIO menu.

FAS1 Usage

The menu for FAS1 Options will only function if you have a FlashAdvance Cartridge in Slot-2.

  • Set .GBA/.BIN/.SAV files as visible in your file listing
  • Allow you to select a .GBA/.BIN file and flash it to the cartridge in Slot-2 (.BIN = PogoShell)
  • Select a .SAV file to flash to SRAM Bank 1 of the FlashAdvance Cartridge
  • Use the Key Combo L+B+A while highlighting Slot2 Card in the root file listing to back up SRAM Bank 1 (backs up to /SAVES/ directory as BANK1.SAV)

Note: The "Use Flash Advance Features" is always set to "Disabled" upon AKAIO startup.

EZ-Flash 3in1

AKAIO supports native loading of GBA games into an EZ 3in1. If an EZ 3in1 is detected, it will show .GBA games. These games are launched by pressing A, then AKAIO will autopatch the game (for save type) and flash it to the NOR or PSRAM of the EZ 3in1 depending on your settings and the game's file size. The save file for the game will be loaded/saved depending your settings. The next time a GBA game is launched SRAM is overwritten as the EZ 3in1 shares an SRAM bank for saves. Make sure to back-up your save files!

  • NOTE: If an EZ-Flash 3in1 was purchased more recently then it may be a "3in1+" and will require AKAIO 1.4 to function fully. This includes the browser support and rumble support. GBA ROM flashing and playback has been supported on the new 3in1+ since AKAIO 1.3 Final.

EWin 2in1

AKAIO supports the EWin 2in1 unit in similar ways to the 3in1.

FlashAdvance Pro

The FlashAdvance Pro is supported via FAS1 integration.

Wi-Fi Update

Start > More > Wifi Update which will bring up the Wi-Fi Update Window. Press X or touch Wifi Update for a Cheat DB update. Press SELECT or touch Loader Update for updating the AKAIO loader. Pressing Y will begin the savelist.bin updater, which is mainly useful for AKRPG users.

If you are having problems connecting via Wi-Fi, enable "Broadcast SSID" on your wireless router.


Start > More > Help displays information on the various button shortcut combinations. This window will usually also display the current build of the AKAIO firmware which is running. The icon in the upper-right hand corner can be used to shut down your NDS by single-clicking on it.

DMA Mode

Games are loaded via DMA mode by default, which enhances performance in many games. AKAIO on the R.P.G. uses DMA on the microSD at all times with currently is no way to turn it off. On the AK2 DMA is active when the "Loading" text turns red.

In v1.4 a new patching (unnamed) mode has been introduced, to use this mode hold X. You can see that this mode is working when the "Loading" text turns green. This new mode fixes video and sound glitches which occur in older patching modes, and offers faster save writing/reading support. As this is still experiental it is not yet a default setting.

If you encounter a problem with a particular game, you can disable DMA mode by holding the A button while loading. In this case the "Loading" text will stay blue.

For games that are problematic with DMA mode, please make sure to first update the loaders to the most recent version. Updated loaders can be found at the Loaders Download Page or via Wi-Fi Update from within AKAIO. If you notice a problem even with the latest loaders, please visit the AKAIO ROM Compatibility Page. Add your problematic game as needed by following the on-site instructions.

Tips, Tricks, and Button Combinations

  • Press L+R+B+A+Down on the D-pad while in a Rom to reset to the AKAIO menu.
  • While in-game, Start+Select+Up enables cheats, Start+Select+Down disables cheats.
  • To hide files that are not used, open globalsettings.ini and add the line : hiddenFileNames = __aio. Then just type a file or folder you do not wish to see in the AKAIO menu screen and separate them by commas. (IE: hiddenFileNames = __aio,moonshl,example,example2). You can also Hide files by using the computer's hide feature but some homebrew may not work.
  • If you're experiencing lag while scrolling files or loading/running games, use the Panasonic SD Formatter to noticeably improve your cards speed (formatting with Windows doesn't correctly allocate files).
  • If your game folder has lots of games it may take a while to load. To speed things up you can separate the games into folders. What some people do is order them into alphabetical folders (A-D, E-I, J-K....) or you can organize them by type of game (Action, Adventure, Platformer, RPG, Shooter...)
  • To hide the file extensions (from "bobsgame.nds" to "bobsgame"), open globalsettings.ini and add the line: hideExtension = 1
  • To force AKAIO to always load the Root directory, open globalsettings.ini and add this line: enterLastDirWhenBoot = 0
  • To turn off the EZ 3in1 start up check, open globalsettings.ini and add this line: EZ3in1startupcheck = 0
  • If you are having problems with a particular game, press and hold A while loading the game. This will disable DMA mode, which may help.
  • Try using the latest loader as it may contain recent game fixes. AKAIO loaders
  • Enable the "Broadcast SSID" feature on your wireless router, if you have problems updating via Wi-Fi
  • If you have problems with cheats not working, you need to enable the cheats globally first. Go to Start > System Options > Default Patch Options, and enable "Cheat Code Use". Then enable the cheats on the game you want.
  • If the Moonshell 2 loading screen freezes on the error message, check the moonshl2 directory for a text file called logbuf.txt. If you see it, delete it, then try loading Moonshell 2 again

Real Time Save and In Game Guide

These features are not planned for future inclusion into the AKAIO firmware. We recommend that you drop an e-mail to [email protected] and bug the Acekard team instead.

In Progress

Nothing here is guaranteed, but it's always nice to let people know what's the focus:

  • Hide filename extensions option in settings window.
  • Block R4 Ultra and R4i
  • Make tabs store childwindows instead of just spinboxes.
  • Better Font Support
  • Integrating many of gelu's changes based on his R.P.G. loader.

Public Betas

Public Betas appear from time to time and will only be released on the GBATemp AceKard Forum. They are not to be mirrored anywhere, and are unsupported. Bug reports are welcome, though.

Main Authors

  • Normmatt - Kiwi. Low-level + Loader man.
  • Smiths - Drinks a lot + Wifi/GUI mods + customer support.
  • gelu - Keeps the Acekard R.P.G. useful.






Contained here are some of the more common Acekard and AKAIO frequently asked questions. These questions appear in no particular order.

  • Does AKAIO work on the AK2i?

YES, use version 1.4.1 or later.

  • Does the AK2i work in the NDSL and NDSPhat?


  • Should I buy an Ak2.1 or an AK2i?

There is a very real possibility that sometime in the future Nintendo could block the use of the DSi exploit. Current DSi kits should be purchased with this in mind. If you only have a DSi then use/purchase the AK2i. If you currently do not have a DSi, it is strongly recommended that you wait. As of right now none of the DSi specific functions (Games, DSi-ware, features, etc) have been hacked. There is a strong possibility that the encryption may never be hacked. Make your informed purchases carefully.

  • Where is the best place to buy an Acekard?

The 'best' place to buy an Acekard is entirely subjective to what your priorities are (price/delivery time). Some places, like Deal Extreme are on the lower end of the price scale and offer free shipping, but delivery time is quite slow @ 2 weeks, which can seem like an eternity when having to wait. Other sites like Real Hot Stuff offer quick delivery, but the price is higher. A good place to start is the Acekard official reseller list where you can compare prices and delivery variations.

  • Why do some sites sell the AK2.1 for $12 USD and others for $30 USD?

Some high volume sites sell the cards just over cost, while others charge double cost to make a profit. You are getting the same kit no matter what price you pay. So buy from a retailer you trust who can ship to you in a professional timeframe. Then sit back and enjoy!

  • Does AKAIO cheat patch GBA ROMs?


  • Will GBA cheat patching ever be added?

It has been discussed, but no plans have been made. This goes beyond just a cheat engine for GBA, it also requires that someone builds a cheat database which can easily be plugged into the existing cheat engine (with a few modifications).

  • Why should I use AKAIO vs. Official firmware?

Right now the two firmwares can not be compared. AKAIO is leaps and bounds ahead of the firmware it was once based on. It features better compatibility, more options, more behind the scenes optimizations, better 3in1 support, anti-piracy patching, WI-FI updates, multiple patching methods, faster directory scrolling, more soft-reset fixes, a rewritten cheat engine, an active development team, and much more.

  • I am having AK2.1-to-AK2.1 local WI-Fi problems, why?

This is a hardware limitation and not an AKAIO problem. Please contact [email protected] with your concerns.

  • AKAIO just started to do strange things, how can I fix it?

Try deleting Optionslist.bin or globalsettings.ini and then relaunch the firmware. Sometimes these files can become corrupt, expecially if you copy/past them during a firmware update.

  • I need to report a bug, where can i do this?

Use the AKAIO BUGDAR. Please do the research first and do not post a bug which has already been submitted.

  • I would like to give suggestions and talk to the AKAIO team, how can i do this?

/join #acekard on the GBATemp IRC network. Please ask your questions/make your statements and then idle. The devs do not type on your schedule.

  • My Acekard stopped working, what now?

Did you format the microSD with the Panasonic formatter and then put AKAIO back on? Does your microSD work in another flash kit? Does your Acekard work in another NDS? If you have fully debugged and it still isn't working than perhaps you have a faulty kit. All Acekard products come with an unspoken 1 year warranty. First contact your retailer and ask for a replacement. If they will not replace it then contact Team Acekard. Team Acekard usually asks for proof that you attempted to get it replaced, and for digital images of your flash kit in various states of use. Be prepared to go back and forth on a few e-mails before getting a replacement option.

  • AKAIO is in a compressed archive, what is this?

AKAIO is uploaded in either a ZIP or RAR format. These formats allow for a folder containing multiple files to be added to a solid archive. This essentially makes it easier to distribute the files as they can be mirrored as 1 compressed file. We strongly recommend winRAR which is a freeware application available for Windows, MAC, Linux, and other Operating Systems.

  • Game XXXX - WHATEVER.nds fails to load, does not work, has problems, etc. Now what?

Patches (soft-reset, cheats, etc) are written to RAM before the game is loaded. In some cases the game will attempt to overwrite the area of RAM that the patches are using. This can cause the game to fail in various ways for different situations. Before you complain that a ROM is not working try to debug the problem yourself. Turn off various patches; try the DMA, Non-DMA, and DMA-Save modes. In rare cases you need to set the save type by hand. You can find out the save type of your ROM by looking up the ROM number at For more information on patching, save types, and other AKAIO tweaks please read the WIKI above. When you have found a fix for a specific game please add it to GBATemp's AKAIO ROM Compatibility WIKI.

  • Why should I bother to use the Panasonic SD formatter?

According to Panasonic "SD/SDHC Memory Card file systems formatted with generic operating system formatting software do not comply with the SD Memory Card specification." This means that your O/S's build in drive formatter is not designed to format the exact set of circumstances that allow your microSD cards to function at their peak performance. While this may not be important for your Cell phone, it is very important when talking about ROMs and read/write access speeds which pertain to NDS flash kits.

  • What is the difference between FAT32 and FAT16?

The File Allocation Table FAT (also known as FAT16) standards were developed before large devices existed. Without getting into the specifics, the general rule of thumb is to format your less than 2GB non-SDHC cards at FAT16. Anything over 4GB should be formatted using FAT32. While you can force some formatters to format a 4GB card at FAT16 you will see a significantly negative performance impact. In some cases, on slower 2GB or less MSD cards you can adjust the cluster size to improve performance. (IE: format G: /Q /A:64k /FS:FAT). For more information please read the File Allocation Table WIKI.

  • My microSD is acting odd, should I defrag it?

NO, NEVER, EVER, defrag your microSD/SDHC cards. Each card has a limited number of read/writes before they cease to function. The best solution is to copy everything off, format using the Panasonic SD formatter, then copy everything back. A freshly formatted microSD will perform better than a defragged one!

  • What are the differences between the various builds of the Acekards?

The AK2 suffered from a manufacturers soldering error. This problem caused the later batches of the Green PCB AK2 to experience a FAT issue. The cards would stop working some time between 2 weeks and 8 months, depending on usage. The AK2s were then pulled and fixed, relabeled, and released as the first batch of AK2.1s. These light Green PCB Acekards have a small chip under the sticker. They are essentially the AK2 repaired, which means the internals are the same. The kits were later redesigned and re-released as the AK2.1 Black PCB. The Black PCB contains a new controller chip and features a permanent redesign of the PCB which insures that FAT error will not happen again. This version of the Acekard 2.1 was also issued as a darker Forest Green PCB. The kit then went back into development and was released a 3rd time with a metallic Blue PCB. The Blue PCB features a new shell. Acekard took out the spring loaded microSD slot and the shell clips in favor of glue. In the end all versions will work and do what you expect. Do not panic if you receive a Green PCB over a Blue PCB.
