If you are reading this then you probably want to update your emunand on your Gateway flashcard, however have realised you can't because Gateway only currently supports up to firmware 9.5.0-23 and the latest firmware is now 9.6, resulting in a black screen and broken emunand after updating to 9.6. However not all is lost, you can safely update your Emunand offline, this tutorial will show you how to update your 3DS's emunand to 9.5.0-23 EUR or USA. Please note this will not work on the "New Nintendo 3DS" Just the 2DS / 3DS and 3DS XL. If you can find the 9.5.0-23 firmware for the New Nintendo 3DS then you can follow this tutorial, however i dont have the firmware for the New 3DS unfortunately. This tutorial presume you have already set-up your Emunand, if not you first need to follow the tutorial here: Nintendo 3DS Homebrew / Rom Hack For Any Firmware Up To 9.2 with Gateway Flashcard. To follow this tutorial you will need to download: BigBlueBox - Nintendo 3DS Dev Menu / CIA Installer Nintendo 3DS 9.5.0-23-EUR Firmware or Nintendo 3DS 9.5.0-23-USA Firmware depending on the region of your console Gateway Ultra 3.1.1 Public Beta Updating your Gateway Emunand to 9.5.0-23 EUR / USA: You need to copy the latest Launcher.dat from the Gateway Ultra 3.1.1 Public Beta to the root of your 3DS's SD card, as shown below. After you then need to download the Nintendo 3DS 9.5.0-23 firmware which corresponds to your region, again this need's to be unzipped so all the .cia files are in a folder on the SD card, as seen below: Inside your firmware folder on the SD card you should have many .cia files: Now if you don't already on the Micro SD card inside your Gateway you need to copy the BigBlueMenu.3ds rom: You are now ready to update your emunand, power on the 3DS with the Gateway flashcard in and launch the exploit to boot in to emunand. Once emunand had loaded press the "Select" button on the 3DS and load the Title Manager (BigBlueMenu.3ds) that we just copied to the Micro SD card inside your Gateway: Now click right on the d-pad once to reach the SDMC tab, then select the folder with your firmware and press "A" to open it: You should now see all the .cia files in the folder: Press down on the d-pad until you highlight one of the files in the folder: Press L+R+A in that order to install all of the cia files which are in the folder: This will take some time: When the install has finished power off the 3DS, then switch it on again and load your Emunand: Once in emunand if you load the system settings you should see that you are on firmware 9.5.0-23: Congratulations your emunand is as up to date as it can possibly be at this point, you will have no problems playing any game released to date.
