I have a Japanese New 3DS and I was just wondering if there's any way to get certain cross-region things working with custom firmware. For example, I can't Download Play from another region 3DS or to another region 3DS. I even tried downloading the Japanese version of Download Play from 3DNUS and installing it on an American O3DS, but it didn't detect anything being sent. Another thing is that I can't start a Download Play session from another region's cart. When I try to run a Download Play server of Luigi's Mansion: Dark Moon using NTR CFW on my N3DS, it just says "Communication lost." The last, and possibly most important thing is that while StreetPass activates on some titles, usually older ones like Super Mario 3D Land, Nintendogs and region free ones like Pokémon, newer titles like Animal Crossing: New Leaf, Tomodachi Life, and A Link Between Worlds all ask me to agree to the 3DS Service User Agreement. Tomodachi Life even goes so far as to bring up the Service Agreement (in Japanese) and then it pretends to activate StreetPass, which doesn't work, since when I actually try to do something involving StreetPass, it just says there was an error. Kingdom Hearts 3D also brings up the agreement, but it just says that StreetPass couldn't be activated. I'm not sure if there's even a way to currently fix these problems. In fact, I'm wondering if it's even possible to fix them, short of a region change (which I don't want to do). Is it even possible to get either Download Play and/or StreetPass working with out-of-region titles? EDIT: Nevermind on StreetPass, I followed this reddit post and got it working.
