Uh, I tried to put every single folder with the ID's and I tried both NTR CFW (also with 3.2 and 3.4) and Luma methods with them, but nothingYeah, I don't know why it's not working for you. Sorry. :/ I know for a fact it works for the US version, both NTR and Luma methods, so... :/ Maybe choose a different version of NTR instead of 3.6? Maybe 3.3 or 3.4/whatever's available?
I noticed that whenever I used NTR CFW with other games, always appeared a green flash when the "3DS" logo started, but this never appeared on the top display of my 3DS using Fates & NTR
so I checked the ID of my game in FBI, and it's 000400000017A400, so not 000400000017A800, but that's quite strange, should I just rename the folder?
