Nintendo switch input display meant as a replacement for OJDS-NX, because OJDS-NX causes load times to increase in some games. This can still be the case with this input display, but it is minimal.
Use devkitPro and make to build
Build with CMake, use MSys2 on Windows
Place the .nsp in /atmosphere/contents/0100000000000901/exefs.nsp, the toolbox.json in /atmosphere/contents/0100000000000901/toolbox.json, and create /atmosphere/0100000000000901/flags/boot2.flag
Put your switch IP in config.ini, and run the display program (make sure the sysmodule is running on your switch). Press L + ZL + ZR + R + Plus to restart the input server.
