Technical notes

Suyu is a standalone Nintendo Switch emulator, community fork of yuzu after legal takedown. dev.keys can be used instead of prod.keys when use_dev_keys is enabled (for Switch dev units). Firmware (system NCAs) must be installed through Suyu's UI from a firmware ZIP or NCA folder. Required for commercial games. Homebrew (.nro, .nso) can run without keys or firmware. Original repos DMCA'd by Nintendo. Analysis performed from community mirror (Hengle/suyu-emu).
