Wumiibo is a rewrite of the 3DS' nfc module, to allow for emulation of amiibo. As Wumiibo does not actually use nfc, this allows it you work on "old" 3DS family consoles, or consoles with Wireless Communication turned off or disabled.

Scroll down and tap on "amiibo Settings"
Select "Register Owner and Nickname"
Press L+↓+START to open the Wumiibo Menu

Press L+↓+START to open the Wumiibo Menu
Select Select a figure. -> <TitleID> -> <amiibo name>.bin
The amiibo will now be emulated, and act as though its always "on" the nfc reader
If the game asks to remove the amiibo, relaunch the Wumiibo Menu and select Force Stop Emulation.

Using real figurines

Wumiibo doesn't work with real figurines, in order to use your physical amiibo again, do the following:

Launch Wumiibo-Helper from the HOME Menu
Select Toggle Wumiibo State
Press B to reboot
- If disabling doesn't work make sure you don't have 2 versions of Wumiibo installed (see "Conflicting Wumiibo versions" in the troubleshooting section)
Repeat steps 1-3 to toggle Wumiibo back on

Troubleshooting

Workaround for freezing games

If the game freezes or lags when trying to scan amiibo, do the following:

Navigate to the screen that asks you to place your amiibo on the screen
Press HOME to suspend the game
Press L+↓+START to open the Wumiibo Menu and select your amiibo
Reopen the suspended game

Conflicting Wumiibo versions

As of v4.2, Wumiibo has switched to a .CXI sysmodule supporting Luma3DS 13.0+, this means you may have two versions of Wumiibo installed to your system:

If you've installed Wumiibo previously, delete the 0004013000004002 folder in sd:/luma/titles/

Alternate menu combo

If one of your consoles buttons are broken download an alternate combo:

Go here, click on the 3 dots, and select download
Copy wumiibo.ini to the root of your SD card

- This will change the combo to open the Wumiibo Menu to R+↓+START
- You can edit wumiibo.ini in a text editor to change this combo

Unable to update Luma

If for whatever reason you are unable to update to Luma3DS 13.0+ (using a special build of luma, etc.) downgrade your Wumiibo version instead:

Download the 4.1 version of Wumiibo (the 0004013000004002.zip)
Extract the zip, and copy the 0004013000004002 folder to sd:/luma/titles/
Ensure that game patching is turned on in Luma Config by powering on while holding SELECT
