nxboot

CLI tool for Nintendo Switch RCM payload launching (Fusée Gelée). Uses Zig and libusb.

Requirements

• Zig 0.15.2

Usage

1. Put the console in RCM and connect it to your machine via USB.
2. Run:

zig build -Doptimize=ReleaseSafe run -- /path/to/payload.bin

Note: with a Debug build (-Doptimize=Debug), resulting RCM payload buffer is also written to debug_payload.bin in the current working directory.
