Nintendo Switch Reverse Engineering
This project is a collection of research and tools for reverse engineering the hardware and communication protocols of Nintendo Switch consoles and controllers. It provides a comprehensive toolset for analyzing physical hardware interfaces, parsing controller communication protocols, extracting embedded firmware, and emulating input signals.
The project focuses on decoding raw serial data and packets from controllers to extract input and sensor states. It includes capabilities for simulating hardware signals to send spoofed input data to the system console and extracting microcontroller software from hardware components, such as docking stations, via serial interfaces.
The technical surface covers hardware interface analysis, including PCB pinout mapping and the study of capacitive touch controllers. It also encompasses the extraction of motion sensor data, the dumping of SPI flash memory, and the definition of low-level communication standards for wireless and wired interfaces.
