notes: |
|
|
Sudachi is a standalone Nintendo Switch emulator forked from yuzu early
|
|
access 4176 (README.md:1-4). Keys are read from the keys directory of the user data
|
|
directory named in data_root (src/common/fs/fs_paths.h:8-9, 18).
|
|
RetroBat creates the user folder beside sudachi.exe before launching
|
|
sudachi.exe -g <rom> and never copies keys itself.
|
|
Key loading stops when neither prod.keys nor title.keys exists
|
|
(src/core/crypto/key_manager.cpp:649-652).
|
|
Firmware (system NCAs) is installed through the UI (Tools, Install
|
|
Firmware, src/sudachi/main.cpp:4130), not read as loose files.
|
|
Commercial games need the keys. Homebrew (.nro, .nso) runs without keys or firmware.
