I have looked but not really found definitive answers. One question may not fit here but i hope someone will still know. First is anyone using like a 256 gb micro sdxc card in there n3ds ? Something like a uhs 1 or 3? Currently have a 128gb, but bigger is always better. Second, anyone got a life hack to make the sytlus more secure in the slot> It doesn't fall out or anything but it does "wiggle" in there and thats just annoying. And lastly is there a homebrew program i can run to improve the sound while wearing headphones? Make it louder, deeper and richer?
