What firmware are you on? Xenoblade Chronicles, for example, doesn't work with regionTHREE/FOUR if you're running 9.0 or 9.2 (the game requires 9.4).New template. Same thing...
If you aren't using a JP console and have it fully updated it will not run. I want confirmation from someone on a JP system that it doesn't work on Sky3DS.
I would like actual proof from someone who didn't just register. Ironically I no longer have the JP motherboard that is in my avatar pic. I swapped it for a US one many months ago and then 2 weeks later the Gateway exploit was released -_-
