3dsnix

This work-in-progress LovePotion app allows you to use a 3DS to control your Switch via network thanks to sys-botbase

Initial Requirements

• Nintendo 3DS with Luma3DS
• Nintendo Switch with Atmosphere

Install

• For the Switch, download the latest sys-botbase sysmodule and extract the archive to the root of SD card
• Check if the sysmodule is installed by rebooting your console - you should see the home button glow on boot if its installed
• For the 3DS, download the latest LovePotion release for Nintendo 3DS and put lovepotion.3dsx in /3ds/lovepotion
• Create a folder /3ds/lovepotion/game and put main.lua in it
• Launch LovePotion via Homebrew Launcher
• On text prompt, input the Switch's IP address (see via System Settings > Internet)
• After a while, the 3DS should connect to the Switch and accept inputs

Current State

• 3DS shows up as a Pro Controller by default
• D-Pad, ABXY and L/R buttons are supported
• Minimal interface to check the stick state and last button change

What could've been

In an order of somewhat importance

• Sticks and ZL/ZR support
• Bundle releases as a separate .3dsx file
• Pretty UI
• Quick reconnect
• Error handling
• Spoof 3DS as another controller (Sideways Joy-Con, for example)
• Maybe a Nintendo DS version? Or at least rewrite this in C or something, who knows.
