This one is US (tho may work for whole NA region with HomePass). I remember there was some Charizard or whatever event in Europe and my 3DS (USA region) didn't get it, even tho my HomePass was set correctly.
most Nintendo Zone events are region locked. Plus apparently you need the correct encryption for it to work.
This homepass allows users to use the "connect via internet" option in mystery gift of Pokemon,
without having to enter the internet into your Nintendo 3DS settings, as it properly emulates the Nintendo Zone.
However, these are the criterias to getting the proper event:
1. correct 3DS region (can be bypassed with emunand region change. theorized that NTR language plugin will work, but have yet to try
eDIT: NTR will only work when NZ hotspot ping appears)
2. your Nintendo Zone file in your 3DS is latest, at v17409 (which is firmware 10.0.0-27; can be bypassed on lower firmwares by installing the 000400DB00010502.cia v17409 from 3DNUS)
Anyhow,
