This guide should help, farosh is easiest. I have farmed prob a 100 horns with the method below but still a pain to light fire, shoot, repeat.

@skoolzout1 great work on these botw cheat codes. Is it possible to have a cheat that will let you keep getting dragon scales/horns/claw/tooth as you shoot the dragon? That way you don't have to wait the next day. I'm sure there is a limiter in the game that only lets you get one dragon artifact...
I spoofed to 5.5.1U just now after reading about update in the news. TUBEHAX blocked the official update. Here's what i did:
1. went to wupinstaller.com on my PC and got latest version pack for my wii u (USA for me)
2. erased all content on my SD card and extracted the install folder and all...
For anyone who cares, I had a hard time updating splatoon disc to 2.4.0 using WUPInstaller but finally got it to work. I have 5.3.2.
1. Using NUSGrabber get splatoon, for US update (NUSgrabber.exe 0005000E10176900)
2. copy all content of the subfolder 0005000E10176900 into a SD card folder...
