-  Citra 3DS emulator (pre-Azahar). Data dir: citra-emu.
-  HLE for most services — files optional. AES keys most important.
-  File locations: sysdata/ for keys/boot/font/seeddb,
-  nand/ for NAND filesystem, nand/private/ for movable.sed.

+  Citra 3DS emulator. Upstream taken down March 2024 (Nintendo lawsuit).
+  Mirror: https://github.com/citra-mirror/citra
+  Data dir: {save_dir}/Citra/ or {system_dir}/Citra/
+  ref: src/citra_libretro/citra_libretro.cpp:460-466
 
-  Key file: aes_keys.txt (NOT keys.txt — that's Azahar).
-  ref: src/common/common_paths.h:68
+  HLE for most services. Embedded open-source replacements for shared font,
+  Mii data, country list, and bad word list compiled into the binary.
+  ref: src/core/file_sys/archive_ncch.cpp:9-27, 133-167
 
-  Azahar fork: see emulators/azahar.yml (uses keys.txt, data dir azahar-emu).
-  citra_canary: same repo, see emulators/citra_canary.yml.
+  firmware_count absent in .info (= 0). All files optional.
