How to install .cia files on 3DS via Gateway 3ds card?

Requirements:

BigBlueMenu : cia file installer

BigBlueMenu is an improved version of the Devmenu and it was made by BigBlueBox.
The Devmenu/BigBlueMenu is a program for the 3DS that allows the management of programs installed in the 3DS. That means that it is possible to install and uninstall programs in the 3DS using BigBlueMenu.

Step 1:

Download the BigBlueMenu file here http://www.3dstwocard.com//show.php?id=102 and extract the contents to your computer. Go inside the created folder and you'll find another folder named "For the 3DS SD card".

You will get these two files. One is in 3DS format, the other is for CIA format. Only the BigBlueMenu.3ds can be used via Gateway red card, so put it to your micro sd card(red card one). And put BigBlueMenu.cia to the root of your SD card (the one inside the 3DS).

Step 2:

Now Gateway card only support 3DS System v4.1 to V9.2. You can then load into the GW mode while the guide here. ( if you con't know how to use the Gateway card please follow this tutorial: How to use the gateway 3DS card ?)

Step 3:

Press the select, you will see the game menu and find this one (BigBlueMenu). Choose it one just like you do for a 3ds game. In the 3DS menu, the BigBlueMenu's icon will appear.

Tips:

  • Do not try to open installed programs while you're on sysNAND menu even if they show up because it won't work and might cause problems. The exception is if it is patched to work on lower firmware version.
  • CIA's can be risky and it is only recommended you do so on Emunand, not your Sysnand.
  • After installing, you don't need the cia file anymore since the game is installed already and so you can delete it from the SD card in order to save space These program will always show on the menu.
  • You can install the game pathcs, dlc patchs and 3ds game. But you can't install the DS game. The cia file is wonderful and very convenience.
  • CIA games are always smaller in size than their rom counterpart. Usually the size that they have and that you can see in the computer, will be the size they'll occupy on your SD card after being installed.
