Gateway 3DS is a hardware and software solution for backing up and playing 3DS Roms.<\/p>\n
The hardware represented by two 3DS cartrigdes (Red and Blue card) with slots for you to insert microSD cards. The software is a file called launcher.dat. As of 10 Jan 2015, the latest version of Gateway 3DS software is “Gateway Ultra 3.0 – Public Beta”.<\/p>\n
As of writing, the Gateway 3DS allows you to:
\n1. Play retail cartriges from other regions
\n2. Partition your 3DS’s memory card into exactly 2 portions: SysNAND and EmuNAND
\n3. And of course, backup your retail cartridge as a ROM, and play ROMs
\nWith each Gateway software update, more features are updated, bugs are fixed. You have to visit the official website to find out more.<\/p>\n
Some terminology of my own, cos it’s so confusing:<\/strong> What systems will it work on?<\/strong> What does it do to my console exactly?<\/strong> Caveat emperor: In the past, there were people using clones of Gateway, and the offical Gateway people decided to brick all consoles running the fake Gateway cards. It seems silly to me that there’s a clone of a cloning device, and even more silly that the first clone decided to intentionally brick all consoles using the fake Gateway cards. Well anyway. You have been warned, there is a certain risk to using Gateway.<\/p>\n What is SysNand and what is EmuNand?<\/strong> In the Gateway menu, there is also an option to format SysNand (which you should do AFTER you backup SysNand). Formatting the SysNand will split your CSD exactly into 2 portions.<\/p>\n If you had a 4GB CSD card, 2GB will be allocated to SysNand, and 2GB will be allocated to EmuNand. (Probably)<\/p>\n SysNand: The original existing system firmware version on your console. EmuNand: Gateway Mode (Pressing SELECT will bring up the ROM Menu) EmuNand: Gateway Classic Mode (Pressing SELECT will NOT bring up the ROM Menu) Gateway menu: So why do I need two Nands for, exactly?<\/strong> This feels overly complicated right now. What should I do?<\/strong> Whenever you want to play your ROMs:<\/strong> https:\/\/www.youtube.com\/watch?v=s6Mr6dIk60k<\/p>\n","protected":false},"excerpt":{"rendered":" Gateway 3DS is a hardware and software solution for backing up and playing 3DS Roms.

\nCSD – The microSD\/SD card that’s in YOUR CONSOLE
\nRSD – The microSD card that’s in the RED Gateway Card
\nBSD – The microSD card that’s in the BLUE Gateway Card<\/p>\n
\nYou’ll need any 2DS\/3DS\/3DS XL\/3DSLL console with system firmware within this range: 4.5 to 9.2. You are out of luck if you don’t have a working console within this range. It will work on consoles from ALL regions (US\/EUR\/JAP\/AUS\/KR)<\/p>\n
\nThe inner mechanisms are not exactly known to me at this time, but it is safe to say:
\n1. It runs an exploit on the vulnerable system version to get it the Gateway menu.
\n2. In Gateway mode, you will be able to access ROMs stored on the RSD by pressing SELECT.
\n3. If you shutoff your system and turn it back on, it would be like you never used Gateway before.<\/p>\n
\nIn the Gateway menu, there is an option to backup SysNand. It is highly recommended that you do a backup. Doing a backup will create a “NAND.BIN” file on your CSD, and you MUST copy a backup to your computer.<\/p>\n
\nThis is the current System Version of your console. Rebooting at any time, will bring you back to SysNand. Exiting the “System settings” screen at any time will ALSO bring you back to SysNand.
\nExample system version: 9.2.0-21U<\/p>\n
\nExample system version: GW3D 9.2.0-21U<\/p>\n
\nExample system version: GW3D 9.2.0-21U
\nThis is used mainly to play original cartridges.<\/p>\n
\nThis is where you setup your Gateway related stuff. Updating Gateway card, Boot Classic Mode, Backup SysNand, Format SysNand, etc.<\/p>\n
\nGateway will only work on your console’s official system version (SysNand version 4.5 – 9.2). To put it simply: One day, there will be a 3DS game which requires SysNand version 10, and you won’t be able to play that with a Gateway. Gateway’s solution is to configure your console to have an option of updating the system firmware. Hence there is a SysNand environment and a EmuNand environment. When supported, you will be able to update EmuNand’s firmware to a supported version, so you can play new games, visit eShop, download patches.<\/p>\n
\n1. Buy Gateway (And 2 micro sd cards)
\n2. Backup files in your CSD
\n3. Put loader.dat into CSD
\n4. Run Gateway Exploit, update Gateway software (if available)
\n5. Run Gateway Exploit, Press L to get into Gateway Menu, backup SysNand to computer, then format SysNand.
\n6. Run Gateway Exploit, verify system settings starts with GW, update system online without existing system settings screen.
\n7. Run Gateway Exploit, verify system settings starts with GW.
\n8. You are done.<\/p>\n
\n0. Put your ROMs into your CSD. (Duh)
\n1. Run the Gateway Exploit.
\n2. Press SELECT, choose a ROM, start playing.
\n3. To exit the ROM, press the HOME button, then A, to exit the ROM. Your save data will THEN be written onto the CSD.
\n4. Putting your console to sleep while playing a ROM, MAY cause your game to hang. Supposedly, this randomly happens when you sleep for more than a few hours. When in doubt, exit using step 3 before shutting down your system.<\/p>\n
