In October 2021 I finally took the plunge and started using NintendoClients for a dream I had years prior: to make all Mario Maker 2 data easily accessible to computers. The Pretendo project has been working on a WiiU NEX server for years, and alongside it NintendoClients, a NEX client, has been becoming more stable and safe to run on your personal account. NEX, partially due to the incredible success of many of the games using it like Mario Kart 8 and Splatoon 2, has been extensively documented, to the point where it is fully possible to spoof both the client and server. Since the WiiU, this protocol has been NEX. Nintendo Switch Online games tend to use a specific library with a specific protocol to communicate with Nintendo's servers.

Using the incredible NintendoClients made by Kinnay, I, and individuals from the Ninji Speedrunning discord, 0% discord, and Kinnay himself, we now have an entirely free and public way of accessing data previously only available to the switch itself.

Mario Maker 2 is a game I've played for years, since launch, and I've always been interested in putting my skills in programming to the test here.
