rajkosto/romdump

fusee payload that dumps the RAW FUSE, KFUSE and BOOTROM bytes from a Nintendo Switch.

romdump

Dumps the RAW FUSE, KFUSE and BOOTROM bytes to your microSD/HOST PC via USB/console screen

Usage

1. Build romdump.bin using make from the repository root directory, or download a binary release from https://switchtools.sshnuke.net
2. Send the romdump.bin to your Switch running in RCM mode via a fusee-launcher (sudo ./fusee-launcher.py romdump.bin or just drag and drop it onto TegraRcmSmash.exe on Windows)
3. Read the screen for warnings/errors (fuse bytes will also be printed here, however its much better to read them out from the microSD or via USB with TegraRcmSmash.exe -r)
