==HOW TO INSTALL DEVMENU ON NEW 3DS emuNAND==
*However this works on both New 3DS and Old 3DS

You will need to download:
Any CFW (literally anything but RxTools is recommended)
Decrypt9: https://github.com/d0k3/Decrypt9/releases
Universal Inject Generator: https://github.com/d0k3/Universal-Inject-Generator
DevMenu .cia: https://mega.nz/#!05pkyRjI!sDd5Mj3XSsqPnMh0aW56eEI8iwLs7LT73RGMlG4hQW0

Note: There are multiple CIA installers available. While FBI is the most popular, DevMenu is an official tool made by Nintendo for developers. Because of this, and its cleaner UI, we will be using this instead.

'''Step 0:'''
Download the Universal Inject Generator as a .zip and slap all the files in a folder. Just do it now to avoid confusion later on.
Put Decrypt9's latest update in your /3ds folder on your SD card. It obviously needs a way to launch Homebrew Launcher to work.

'''Step 1:'''
Open Decrypt9 (or Decrypt9WIP if that's what it says in the Homebrew Launcher) and dump a file called "hs.app" from emuNAND. Go to "emuNAND File Options" to "Dump Health and Safety".

'''Step 2:'''
You now have "hs.app" on your SD card's root. Back this up in case you fuck up. Take "hs.app" and put that file into the "input" folder of the Universal Inject Generator, and put DevMenu.cia in there too.

'''Step 3:'''
Run go.bat. You should now have two files: "DevMenu_inject_no_banner.app" and "DevMenu_inject_with_banner.app". If either of these files are larger then the original "hs.app", you fucked something up.
==You want the WITH_BANNER.app.==

'''Step 4:'''
Take "FBI_inject_with_banner.app" and rename it to "hs.app". DELETE the "hs.app" on your SD card and put this new, renamed version on your root.

'''Step 5:'''
Open Decrypt9 again. This time, go to "emuNAND File Options" and INJECT hs.app into your emuNAND.

'''Step 6:'''
==If you want to do this with sysNAND, repeat all the steps listed here but with a hs.app dumped from your sysNAND. A hs.app will NOT work if injected from emuNAND to sysNAND or vice versa.==

'''Step 7:'''
Check and see if it works, and install your free games you fucking faggot.
