Read at each pinned commit: Azahar, Citra, Citra 2018, Panda3DS, Trident, FS-UAE and Stella read these below the frontend save directory, Dolphin and Ishiiruka below <save>/User, Cemu its MLC below <save>/Cemu. Each profile names its library_name. Citra Canary reads sysdata from the host data directory: its pin moves to the canary branch it is built from.

notes: |
|
|
Successor to Citra (via Lime3DS). The libretro core lives in the same
|
|
repository (src/citra_libretro) and is built with ENABLE_LIBRETRO, which
|
|
forces the SDL2, Qt and web service frontends off.
|
|
ref: CMakeLists.txt:40, CMakeLists.txt:109-111, CMakeLists.txt:165-187
|
|
|
|
The libretro core moves the user directory to <save_dir>/Azahar/, or to
|
|
<system_dir>/Azahar/ when the frontend gives no save directory. The core
|
|
option "Azahar Default" keeps the standalone data directory instead.

|
src/citra_libretro/environment.cpp:191-208
|
|
|
|
The core reports library_name "Azahar".

|
|
|
|
Standalone data dir: azahar-emu under XDG_DATA_HOME (Azahar on Windows and
|
|
macOS), with citra-emu and lime3ds-emu kept as legacy locations. A user/
|
|
directory beside the executable (Windows) or in the working directory takes
|
|
precedence. sysdata/, nand/ and sdmc/ sit under the user directory.

|
|
|
keys.txt has an AES-encrypted key blob compiled in, used when the file is
|
|
absent. ENABLE_BUILTIN_KEYBLOB defaults to ON and is not among the options a
|
|
libretro build forces off.

System archives (shared font, Mii data, country list, bad word list) are read
|
|
from installed NAND titles. Open-source replacements embedded in the binary
|
|
answer when the title is absent.
