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.

|
|
HLE 3DS emulator. Most games run without system files.
|
|
Encrypted ROMs need AES keys in sysdata/aes_keys.txt, and seed-encrypted
|
|
titles (9.6+) also need sysdata/seeddb.bin.
|
|
DSP firmware is loaded from the game itself (HLE/LLE/Null modes via core
|
|
option panda3ds_dsp_emulation). System archives (shared font, bad word
|
|
list, country list, mii data) are compiled into the binary via cmrc.
|
|
The libretro core uses the save directory, not RetroArch's system
|
|
directory. Files go under <save_dir>/Emulator Files/sysdata/, under the
|
|
working directory when the frontend gives no save directory. The core
|
|
reports library_name "Panda3DS". Standalone reads them from Emulator
|
|
Files/sysdata/ below its SDL pref path.

note: |
|
|
Loaded at ROM load time from appDataRoot/sysdata/aes_keys.txt.
|
|
In libretro mode, appDataRoot = <save_dir>/Emulator Files/.
|
|
Contains key slot entries (generator, keyX, keyY, normalKey).
|
|
Only needed for encrypted .3ds/.cci/.cxi/.app files.
|
|
Decrypted dumps work without this file.

|
|
note: |
|
|
Used for titles with seed encryption (firmware 9.6+).
|
|
Placed alongside aes_keys.txt in the sysdata directory.
|
|
Without it, seed-encrypted titles fail to load with a warning.
