HAC SDK was updated to 1.0 for the official developer release, they also updated the installer/downloader tool, gearing up for devs/reveal— Nikki 🌐 (@NWPlayer123) September 12, 2016
NWPlayer123 is the woman behind an absolute ton of leaks. We're talking about spot-on content that is 100% accurate. Now she's at it again with some info about the Nintendo developer portal.
According to her, the NX SDK has been updated to version 1.0. Why would Nintendo make a move on this now? If the info is true, it would seem to indicate that Nintendo will be releasing NX details to devs that don't have dev kits yet. This way they can approximate the NX's abilities/powers when developing a game on their PC.
