Hi, I figured I would write this up in case people were having issues with Amiibomb. This is essentially, how to write amiibo to NFC using Arduino IDE. 1.) First, get some NFC215 tags: https://www.aliexpress.com/item/100...lgo_pvid=5e95beeb-6567-43e1-9da0-ded334aa76fe then, download Arduino IDE if you don't have it already: https://www.arduino.cc/en/Main/Software 2.) Download necessary Arduino files: download 'Write_amiibo.ino' within the 'Write_amiibo' folder in the GitHub link: https://github.com/konstantin-kelemen/arduino-amiibo-tools Also, download the 'sketch_may22a.ino' file here: https://drive.google.com/file/d/0B6g_t94t7-WbcWJFZWFObzc0ZG8/view?usp=sharing 3.) Wire up your Arduino exactly as it is set up at the start of the amiibomb thread: https://gbatemp.net/threads/tools-amiibomb.467990/ 4.) First, make sure your board shows up and is connected properly and correctly under Tools->Board and Tools->Port in Arduino IDE, then open the 'sketch_may22a.ino' file in Arduino IDE, upload to board by hitting the circular button with the right arrow at the top left of the program. After it says done, hit Tools->Serial Monitor to view the printout of the code. Hit 'CTRL + C' to copy the UID number in the prinout after it shows up and you select it. (Note, UID numbers are unique for every NFC215 tag.) Example: https://drive.google.com/file/d/0B6g_t94t7-WbUkRTbnp1c0VzQm8/view?usp=sharing 5.) Click the first link in this google search, AKA the heranbago one and download 'key_retail.bin' off of that site to use for any amiibo being made: https://www.google.com/search?q=key...69i57j69i59.5988j0j8&sourceid=chrome&ie=UTF-8 6.) Go to nfc-bank or some other site and download the amiibo.bin files you want, then use this site to input UID number received in the previous program, along with the 'key_retail.bin' file and the amiibo.bin file you found. Next, hit submit and copy to clipboard for the window that pops up. Site to go to: https://games.kel.mn/amiibo/ 7.) Now, open up the 'Write_amiibo.ino' file previously downloaded from the GitHub link. and paste that slew of values under the code comment that says '// >>> Paste your dump here <<<' Example: https://drive.google.com/file/d/0B6g_t94t7-WbcnJUQVZUUXg5QVU/view?usp=sharing 8.) Upload the code, then open Tools->Serial Monitor, then place NFC tag on your reader and wait till the program says the writing is finished. 9.) Enjoy! If anyone has any questions, or I mistakenly included anything that goes against gbatemp terms of service, feel free to comment and let me know ASAP and I'll edit my post accordingly.
