BEFORE ANY QUESTIONS - IMPORTANT: This app is only for the 3DS (not usable for Switch/Wii U or anything else) It is still in development, it doesn't really work and it crashes. What is this: This is a app which tries to make other apps/games in the 3DS think that there is an amiibo being scanned.
Ultimate goal would be to let you unlock/use features which require an amiibo by using a compatible amiibo dump file (Kind used by TagMo/Thenaya/AmiiBomb). Its very much under development at the moment. I'm making the code public and posting this thread in the hope that other more knowledgable developers could help out sort some bugs. This module is meant to replace the native NFC module of the 3DS.
Luma 8.1 A custom "loader" (a modified version from the code made by YifanLu/Luma), which enables loading exefs for a exiting title via a CIA rather than a code.bin. (https://github.com/HiddenRambler/Luma3DS)
- Put the included loader.cxi into /luma/sysmodules folder on the SD card.
- Put the noamii binary 0004013000004002.cxi into the /luma/titles folder of the SD card.
- Put a valid amiibo dump into /amiibo_dump.bin file on the SD card.
- Put the amiibo key file (same as used for Thenaya) into /amiibo_keys.bin file on the SD card.
- Reboot the 3DS. Open amiibo settings panel and you trying to change the owner details or reset an amiibo will bring up a black screen with the prompt "Place Amiibo?" pressing D-Pad Up will simulate placing of an amiibo. pressing any other key will simulate not having an amiibo. (Hint keep pressing B to cancel).
If your amiibo dump has valid Smash bros data you could get it to work within SSB. however attempting to update the amiibo data will cause a crash. Like i said the app currently has a memory corruption issue which is causing the above SSB crash. Any help in figuring it out would be aprecciated. Please try to not post any non development related posts off this thread.
If you are not a developer its not worth trying to get this to work at the moment.
