After some research, I decide to buy N3DS US Mario 3D Land with come with 10.7 Sysnand before I can't find it anymore. Before buying, I decide to study the hax by reading the guide again since I never hack N3DS before here: https://github.com/Plailect/Guide/wiki/Homebrew-Launcher-(Browser). I'm a bit paranoid on disable browser version check step and try to use Google to find more information and found a lot of way to disable it, which make me confuse. So, I decide to come asking it here. Does change DNS Server to 104.236.072.203 is enough to disable browser version check? Thanks!!
