Citra Aes Keystxt Work: !exclusive!
aes_keys.txt file is the central "keyring" that allows the Citra emulator to decrypt 3DS game files on the fly. Without these keys, the emulator cannot read the encrypted data within files, resulting in errors or black screens upon launch. aes_keys.txt System Works The 3DS uses AES-128 bit symmetric encryption
, where the same key is required for both locking and unlocking data. Citra mimics the 3DS hardware's "AES Engine" to decrypt game data as it's being loaded. Decryption on Launch : When you open an encrypted game, Citra looks for the aes_keys.txt file in its internal system directory. Key Matching
: The emulator matches the game's unique identifiers (like Title IDs) with the keys provided in the text file. The Key Source
: These keys are proprietary to Nintendo. For legal and functional reasons, the recommended method is to dump them directly from your own console using tools like File Structure and Setup
For Citra to recognize the keys, they must be formatted correctly and placed in a specific subdirectory.
To make the aes_keys.txt file work in Citra, it must be placed in a specific folder named
within the Citra user directory. This file allows Citra to decrypt encrypted games (like files) without needing to manually decrypt every ROM. 1. Correct Folder Locations The placement depends on your device. If the folder does not exist, you must create it manually. C:\Users\[YourUsername]\AppData\Roaming\Citra\sysdata\ Internal Storage > Citra-emu > sysdata Internal > Citra > sysdata ~/Library/Application Support/Citra/sysdata/ Linux (Flatpak) ~/.var/app/org.citra_emu.citra/data/citra-emu/sysdata/ Steam Deck (EmuDeck) /home/deck/Emulation/bios/citra/sysdata/ RetroArch (Citra Core) retroarch/saves/Citra/sysdata/ 2. File Naming and Format : Ensure the file is named exactly aes_keys.txt in all lowercase. Common Error : On Windows, ensure you haven't accidentally named it aes_keys.txt.txt by checking your "File name extensions" setting. : The file should contain a list of hex keys (e.g., [Slot] = [Key]
). These keys are typically dumped from a 3DS console using tools like to avoid copyright issues. 3. Troubleshooting "Still says encrypted"
: Restart Citra after placing the file. If it still doesn't work, your keys might be outdated or missing a specific key for that game. Decryption Alternative : Many users find it easier to use a Batch 3DS Decryptor on their PC to convert encrypted
files into decrypted versions, which eliminates the need for aes_keys.txt Shared Keys
: Distribution of these keys is legally protected by Nintendo; it is recommended to dump them from your own hardware using a GodMode9 script Are you trying to run a specific game that is still giving you an error after placing the keys?
The aes_keys.txt file is essential for Citra and its derivatives (like Folium) to decrypt and play encrypted Nintendo 3DS ROMs. Without these keys, encrypted games will fail to load, often displaying errors such as "missing keys". Key Functionality
Decryption: The aes_keys.txt file contains symmetric cryptographic keys used by the 3DS hardware to protect software data.
File Format Support: While decrypted ROMs do not require this file, encrypted files (standard dumps from a console) must have these keys to be readable by the emulator.
Advanced Features: Beyond just launching games, these keys can enable features like Miis, amiibo support, and access to system-level data. Implementation & Setup
To make aes_keys.txt work, it must be placed in the correct subfolder of your Citra user directory:
Standard Citra (PC): Place the file in the sysdata folder within the Citra user directory.
LibRetro/RetroArch: Typically located in ../saves/Citra/sysdata.
Mobile (Folium): The file is imported directly into the app's internal file system, often through an "Import" button in the settings menu. Troubleshooting Common Issues
Incorrect Path: On macOS, the path is usually ~/Library/Application Support/Citra/sysdata/.
Naming Errors: The file must be named exactly aes_keys.txt (all lowercase) to be recognized.
Outdated Keys: If the file is present but games still don't launch, the keys may be old or missing specific keys required for newer firmware versions (e.g., 11.17.0).
Workaround: To avoid dealing with AES keys entirely, many users prefer using decrypted ROMs, which have the encryption already removed and do not require any external key files. Legal & Safety Note
Unlocking 3DS Emulation: Making Your aes_keys.txt Work in Citra
If you’ve ever tried to load a 3DS game in Citra and been met with a "The game is encrypted" error, you’ve likely come across the infamous aes_keys.txt
file. This small text file is the "skeleton key" that allows Citra to decrypt and play games, but getting it to work can be tricky if you don't know where to put it. Why Do You Need It?
Nintendo 3DS games are protected by AES encryption. While some game files (like
) might come pre-decrypted, many standard dumps require system-level keys to run. The aes_keys.txt
file provides these keys so the emulator can decode the game data on the fly. How to Get Your Keys
The most reliable and legal method to obtain these keys is to dump them directly from your own hacked 3DS console using a tool like Run a Script : Use a script like dumpkeys.gm9 in GodMode9. Locate the File : After running the script, you’ll find aes_keys.txt on your SD card in the
: Move this file to your computer or device where Citra is installed. Where to Place the File The most common reason aes_keys.txt
"doesn't work" is that it’s in the wrong folder. You must place it in the folder within your Citra user directory. C:\Users\[YourName]\AppData\Roaming\Citra\sysdata\ Internal Storage > Citra > sysdata ~/Library/Application Support/Citra/sysdata/ RetroArch (LibRetro core) retroarch/saves/Citra/sysdata/
folder doesn't exist, simply create it manually inside the main Citra folder. Troubleshooting Common Issues Incorrect Naming : Ensure the file is named exactly aes_keys.txt . Watch out for "hidden" double extensions like aes_keys.txt.txt Outdated Keys
: If you are trying to play newer titles or DLC, you might need updated keys from a more recent system dump. The "Decrypted" Alternative
: If you want to skip this setup entirely, many users choose to use pre-decrypted ROMs, which do not require an aes_keys.txt file to function.
In Citra, the aes_keys.txt file is a required system file used to load and play encrypted Nintendo 3DS games, such as those in
formats. Without these keys, the emulator cannot decrypt the game data, leading to "must be decrypted first" errors. Purpose and Function
The file contains various cryptographic keys (AES keys) that the 3DS hardware uses to secure its content. These include: Decryption Keys : Essential for loading encrypted game files. System Functionality
: Keys for Miis, amiibo support, and sharing data between systems. Advanced Features citra aes keystxt work
: Enables advanced features in the emulator that are otherwise locked. How to Obtain the File
Due to legal and copyright protections, these keys are owned by Nintendo and cannot be legally distributed online. The official method involves dumping them from your own 3DS hardware: Hacked 3DS : Use a console with custom firmware. GodMode9 Script : Run a script like dumpkeys.gm9 within the menu on your 3DS. File Generation : This process generates the aes_keys.txt on your SD card, typically in the Installation Guide To work, the file must be placed in the specific folder of your Citra user directory.

Citra AES Keystxt — an engineer's little mystery
No one at BitHarbor expected a handful of text lines to cause a midnight scramble. The file was innocuous enough: "keystxt" — a tiny, plain-text blob found on a legacy build server labeled Citra_AES. To Rowan, the senior engineer on call, it looked like artfully-labeled garbage. To Jun, the security intern, it looked like a dare.
They opened it together. The file contained nothing like keys you could paste into a wallet. Instead it had short lines that read like zeroth-order poetry: hex pairs, timestamps, and short phrases—"greenshift", "market25", "noonmask". Every line ended with a four-character checksum that didn’t match any standard format they recognized.
Rowan’s first instinct was mundane: leftovers from a CI job, a debug dump from some long-retired encryption routine. Citra_AES sounded like the company's internal AES wrapper from a decade ago. But Jun noticed the pattern: when she converted the hex pairs into ASCII and then XORed adjacent bytes with a repeating key of length 3, some of those short phrases expanded into fragments of sentences. "…meet at…", "…bring the…", "…not the vault…". Not code. Not debug. Messages.
The server's logs showed one curious thing: an automated process running nightly named "keystxt-rotor" that had been dormant for years until a few days ago. Whoever bumped it new had done it quietly from an external IP that resolved to an old partner company nobody used anymore. The lines in keystxt were being updated at 00:07 UTC each night.
Rowan and Jun set up a sandbox, feeding the file into decoders and pattern detectors while isolating the build machine from the network. The transformed fragments, when stitched into order using the checksums as sequence markers, looked like directions and warnings—phrases about "key rotation", "test vectors", and oddly, "Citra garden". The team laughed nervously at the garden bit. Citra, it turned out, had been a pet project name for the company’s cryptographic library; in the courtyard outside the old headquarters there had once been a citrus grove used as a retreat for engineers. The grove had been paved over years ago.
They dug into version control and found a branch none of the current engineers remembered: "citra/keystxt". Its last commit was thirteen years earlier, by a developer who'd since left. The commit message read: "For the record, if we ever lose formal key storage: seeds in the garden." Rowan felt a chill. Was this whimsy from a nostalgic colleague, or deliberate redundancy?
The next nightly update pulled the team deeper. New lines in keystxt referenced a sequence of coordinate-like pairs. When plotted, they mapped to locations across the city—benches, courier drop boxes, a shuttered bookstore. The checksums, when run through a bloom of simple ciphers, produced short passphrases. The team had a choice: ignore it as a clever puzzle, or follow it.
Curiosity won. Jun convinced Rowan to take an evening and follow the clues under the harmless pretext of team morale. At the shuttered bookstore, tucked beneath a loose brick, they found a weathered tin holding a USB stick and a note in a cramped hand: "If you have the key, rotate it. If not, plant a tree."
The USB's contents were curious: a small, self-contained tool that, once executed in a safe, offline environment, produced a set of AES key derivations and a short essay—an engineer's manifesto about resilient secrets. The manifesto argued for secret-sharing baked into ordinary life: keys split into innocuous artifacts, redundantly encoded, intentionally ephemeral. "We built brittle systems around single vaults," it read. "If the vault goes dark, the system must still sing." The tool also contained a mechanism to validate keys formed from the keystxt phrases.
There was no theft, no exposed credentials; instead it was a time-capsule for future engineers: a kind of insurance policy left by someone who feared institutional amnesia. The keystxt updates were a keep-alive: an external monitoring script pinging the server each night to ensure the chain remained fresh. Whoever maintained it had recently stopped—possibly retired, or moved on—so the nightly pings failed and the data surfaced to the awake team.
Rowan found the story both comforting and unnerving. The manifesto's author had deliberately blurred the line between playful cryptography and operational resilience. The approach was elegant and dangerous: decentralize trust by sewing parts of it into human culture—notes on benches, tins in bookshops—so that even if corporate systems fail, the secret can be recovered by a handful of curious, cautious souls.
They chose a middle path. The keystxt scheme stayed documented and archived, but the team also implemented modern safeguards: distributed key management, automated rotation, and better logging. They left a final note in the tin—a short line of hex that, when decoded, read: "We found it. Thank you."
Years later, Jun would tell the story at onboarding: about the night they chased a file named keystxt and found a gentle, paranoid librarian who'd hidden cryptographic seeds around a city like acorns. It was a parable: code is tools, but people build safety into systems in human ways. The file reminded them that in security, technical excellence and human creativity often walk hand in hand—sometimes leaving riddles for the curious to solve, and sometimes, planting trees for those who come after.
The aes_keys.txt file is a critical system file used by Citra to decrypt and run encrypted Nintendo 3DS games. While many users prefer using pre-decrypted ROMs to avoid this step, this file allows the emulator to handle raw encrypted .3ds or .cia files directly. 🔑 Function of aes_keys.txt
The Nintendo 3DS uses several layers of Advanced Encryption Standard (AES) to protect its software. These keys are stored in the console's hardware.
Decryption: Citra uses these keys to read the encrypted data of a game in real-time.
System Services: Certain keys are required for advanced features like Miis, amiibo support, and shared system fonts.
Alternative: If you do not have this file, you must use a Batch CIA 3DS Decryptor to convert your files into a format Citra can read without external keys. 📂 File Location and Setup
To work correctly, the file must be named exactly aes_keys.txt and placed in the sysdata folder of your Citra user directory. Typical Path Windows C:\Users\[YourName]\AppData\Roaming\Citra\sysdata Linux/macOS
~/.local/share/citra-emu/sysdata or ~/Library/Application Support/Citra/sysdata Android Android/data/org.citra.citra_emu/files/citra-emu/sysdata
Note: If the sysdata folder does not exist, you must create it manually. 🛠️ How to Obtain Keys
According to the r/Citra Guide, the legal and recommended way to get these keys is to dump them from your own 3DS hardware.
Requirement: A 3DS console with custom firmware (CFW) installed. Tool: Use a tool like GodMode9.
Process: Run a script such as DumpKeys.gm9 within GodMode9. This generates the aes_keys.txt file on your SD card.
Transfer: Copy the file from your SD card to your computer or phone in the directories listed above.
For those without a physical console, some users refer to community-maintained guides on Reddit or GitHub for troubleshooting key-related errors. 📝 File Content Structure
The file is a plain text document. Each line contains a specific key identifier and its corresponding 32-character hexadecimal string. Common entries include:
Slot Keys: Labeled as slot0x0DKeyX, slot0x1BKeyX, etc. These correspond to specific hardware encryption slots.
Common Keys: Labeled as common0, common1, etc., used for standard system-wide decryption. ⚠️ Common Errors
"ROM is Encrypted": This means Citra found the game but cannot find the keys or the keys provided are incorrect.
Incorrect File Name: Ensure the file is not named aes_keys.txt.txt (a common Windows hidden extension error).
Outdated Keys: Older keys may not support games that require newer AES encryption slots.
To get aes_keys.txt working in Citra, you must place the file in the correct sysdata folder within your Citra user directory. This file allows the emulator to decrypt and play encrypted 3DS retail games. 1. Locate Your Citra User Directory
The location of the sysdata folder depends on your operating system. If the sysdata folder does not exist, you must create it manually.
Windows: C:\Users\[Your_Username]\AppData\Roaming\Citra\sysdata\ Linux: ~/.local/share/citra-emu/sysdata/ macOS: ~/Library/Application Support/Citra/sysdata/ Android: Internal Storage > citra-emu > sysdata RetroArch (Citra Core): retroarch/saves/Citra/sysdata/ 2. Prepare the aes_keys.txt File aes_keys
File Name: It must be named exactly aes_keys.txt (lowercase, with the .txt extension).
Content: The file should contain the 3DS system's crypto keys. While these can sometimes be found on sites like Pastebin, the official and legal method is to dump them from your own hacked 3DS console using a GodMode9 script. 3. Apply the Keys Close Citra completely.
Copy your aes_keys.txt into the sysdata folder identified in Step 1. Restart Citra.
If your games were not showing up or were throwing "Encrypted" errors, they should now load successfully. Troubleshooting
Games still won't load: Ensure you also have the seeddb.bin file in the same sysdata folder. This is often required alongside AES keys for newer titles.
File Extension Error: Double-check that your file isn't accidentally named aes_keys.txt.txt (common if Windows "Hide extensions for known file types" is enabled).
Alternative: If you want to avoid keys entirely, you can use a tool like the Batch CIA 3DS Decryptor to decrypt your game files directly on your PC before loading them into Citra.
Are you setting this up for a standard Citra build or a specific fork like Lime3DS or Folium?
To get your aes_keys.txt file working in Citra, you need to ensure the file is correctly formatted and placed in the specific "sysdata" folder of the emulator’s directory. Citra requires these keys to decrypt and run encrypted 3DS ROMs (standard .3ds files). 1. Locate the Correct Folder The file must be placed in a folder named sysdata.
Windows: C:\Users\[YourUsername]\AppData\Roaming\Citra\sysdata\ Linux: ~/.local/share/citra-emu/sysdata/
Android: Android/data/org.citra.citra_emu/files/citra-emu/sysdata/
Note: If the sysdata folder does not exist, you must create it manually inside the main Citra folder. 2. Format the File Properly
The file must be named exactly aes_keys.txt. Inside, the keys must follow a specific hexadecimal format. A working file typically looks like this:
slot0x18KeyX=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX slot0x1BKeyX=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX slot0x25KeyX=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX slot0x2CKeyX=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX slot0x2DKeyX=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX slot0x31KeyX=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX Use code with caution. Copied to clipboard
(Replace the Xs with the actual 32-character hexadecimal keys found in your console's firmware.) 3. Verification Steps If Citra still isn't recognizing the keys:
Check File Extensions: Ensure the file isn't accidentally named aes_keys.txt.txt (common if Windows "Hide extensions for known file types" is on).
Restart Citra: The emulator scans for keys upon startup. If you added the file while Citra was open, close and relaunch it.
Check Log Files: Go to Emulation > Open Log Location. Open citra_log.txt and search for "AES" to see if there is an error message stating the keys failed to load. 4. The Alternative: Decrypted ROMs
If you cannot get the keys to work, you can avoid the aes_keys.txt requirement entirely by using Decrypted ROMs. These files have already had the encryption layer removed and will boot in Citra without any external key files.
The neon sign outside the repair shop flickered, casting a restless blue hue across the dusty counter. Inside, the air smelled of solder and stale coffee. Lucas, a man whose life was measured in gigabytes and frame rates, sat hunched over his keyboard.
For three days, he had been staring at the same error message. It was the bane of his existence, a digital gatekeeper refusing him entry into the world he desperately wanted to revisit.
System Archive Decryption Failed.
Lucas was an emulation purist. He believed in preserving the golden era of handheld gaming. He had the emulator, Citra, running smoothly on his high-end rig. He had the game files—legally dumped from his own cartridge, he always reminded himself. But the 3DS architecture was a fortress. Without the specific system files necessary to decrypt the game data, the experience was flat, broken, or simply non-existent.
"It’s the keys," he muttered to his cat, a fat tabby named Zelda who was asleep on a pile of outdated graphics cards. "The console needs to boot, and to boot, it needs to know it’s authorized. It needs the aes_keys.txt work."
To the average user, the term was jargon. To Lucas, it was the holy grail. The aes_keys.txt file was the master list, a digital set of locksmith's picks. It contained the cryptographic keys that the original hardware used to unscramble the encrypted game data. The "work" wasn't just about downloading a file; it was about the intricate dance of placing that file exactly where the software expected it, resolving conflicts, and ensuring the emulator could simulate the security handshake of the physical device.
He had tried extracting them himself. He had spent hours with a modded 3DS, running a custom firmware payload to dump the bootrom and the necessary system archives. He had the seeddb.bin. He had the title folders. But every time he launched Citra, the screen stayed black, or worse—it crashed at the very first logo.
He rubbed his eyes. "I'm missing something. The path isn't resolving."
The irony wasn't lost on him. In the physical world, he could fix a broken cartridge slot with a screwdriver and a steady hand. In the virtual world, he was defeated by a text file.
He opened the Citra forums on his second monitor. This was "The Work." It wasn't playing games; it was the unglamorous, hours-long troubleshooting that allowed the games to exist in the first place. He scrolled past the piracy warnings and the naysayers, looking for the one specific config tweak he hadn't tried.
“Make sure the file is in AppData > Roaming > Citra > sysdata,” one post read.
"I know that," Lucas grumbled. He navigated to the folder. It was there. A tiny, unassuming text file. aes_keys.txt. He opened it. Rows of hexadecimal strings stared back at him. It looked correct.
He decided to start fresh. He closed the emulator. He deleted the sysdata folder entirely. It was a scorched-earth tactic. He re-downloaded the latest nightly build of Citra. Then, with surgical precision, he navigated back to the freshly created directory.
He pasted the aes_keys.txt file into the folder.
Then, he remembered a snippet from a deep-dive technical thread. “Ensure the system archives are placed alongside the keys, or the boot sequence will hang when looking for the font files.”
The "work" was never just one thing. It was a constellation of dependencies. He copied over his dumped system archives—the Shared Font, the User Font, the Mii data. He organized the files, ensuring there were no permission errors.
"Okay, Zelda," he whispered. "Moment of truth."
He double-clicked the emulator icon. The Citra logo popped up, clean and bright. He selected the game icon from his list. The Legend of Zelda: A Link Between Worlds.
He held his breath.
Usually, this was where the screen would flicker and die. Usually, the fatal error would pop up, mocking his efforts.
But this time, a familiar sound chimed through his speakers. The crisp, synthesized chime of a 3DS booting up. The top screen of the emulator window turned white, then faded into the first cinematic.
The frame counter in the corner held steady at 60 FPS.
Lucas sat back, a slow grin spreading across his face. He watched Link tumble out of bed in glorious high definition, the textures crisp, the sound perfect.
The "citra aes keystxt work" wasn't magic. It wasn't a hack. It was simply the price of admission. It was the bridge between the plastic console gathering dust in his closet and the digital preservation on his monitor. It was hours of frustration for seconds of relief.
He stretched his arms over his head. The troubleshooting was over. The gate was open. Now, finally, he could play.
The aes_keys.txt file is a critical system file used by the Citra emulator to decrypt and load encrypted Nintendo 3DS games, such as those in .cia or encrypted .3ds formats. Without this file, Citra cannot interpret the encrypted data, often resulting in errors like "must be decrypted first". How the aes_keys.txt Works
Nintendo 3DS software is protected by Advanced Encryption Standard (AES) keys. When you run an encrypted game on Citra, the emulator looks for these specific keys within the aes_keys.txt file to unlock the content. The file itself is a plain text document containing key-value pairs, such as slot0x0DKeyX=... or common0=..., followed by 32-character hexadecimal strings. Where to Place the aes_keys.txt
For Citra to recognize the keys, the file must be placed in a specific subdirectory within your Citra user folder called sysdata.
Windows: C:\Users\[Your_User_Name]\AppData\Roaming\Citra\sysdata Android: Internal memory/citra-emu/sysdata
Linux/Steam Deck: ~/.local/share/citra-emu/sysdata or home/.var/app/org.citra_emu.citra/data/citra-emu/sysdata macOS: ~/Library/Application Support/Citra/sysdata
If the sysdata folder does not exist, you must create it manually. How to Obtain the File Legally
Distributing these keys is illegal as they are proprietary Nintendo property. The only official and legal way to obtain them is to dump them from your own 3DS hardware using a tool like GodMode9: Preparation: Install GodMode9 on your modded 3DS.
Run Script: Use a script like dumpkeys.gm9 within the GodMode9 "Scripts" menu.
Transfer: Once the process finishes, find the aes_keys.txt file on your SD card in the /gm9/ folder and copy it to your PC or Android device. Alternatives to Using aes_keys.txt

A valid aes_keys.txt file looks like this:
# Slot 0x18 - KeyX for cartridge secure area
[keys]
slot0x18KeyX = 1234567890abcdef1234567890abcdef
slot0x1BKeyY = fedcba0987654321fedcba0987654321
slot0x25KeyX = 0123456789abcdef0123456789abcdef
slot0x2CKeyY = 00112233445566778899aabbccddeeff
Crucial formatting rules:
- The line
[keys]is mandatory. Citra will ignore the file if this header is missing. - Key names must be exact (e.g.,
slot0x18KeyX). - Values are 32-character hexadecimal strings (representing 128-bit keys).
- No spaces around the equals sign (
=). - Lines starting with
#are comments and ignored.
Q: Do I need aes_keys.txt for decrypted ROMs?
A: No. If you have a decrypted ROM (typically .3ds or .cci that have been processed), Citra does not need the keys file. The aes_keys.txt is only for encrypted ROMs.
What is Citra? A Quick Refresher
Citra is a popular open-source emulator for the Nintendo 3DS. It allows gamers to play 3DS titles on Windows, Linux, macOS, and even Android devices. However, unlike older cartridge-based systems, the 3DS employed heavy cryptographic security.
Most commercial ROMs are encrypted. To play them legally (assuming you have dumped your own cartridges), Citra needs to decrypt them on the fly. This is where the AES keys come into play.
Q: I updated Citra, and now keys don't work.
A: Citra updates rarely break key loading, but they can change the user folder location. Check File > Open Citra Folder. The new version may have created a parallel directory. Move your keys file to the new user folder.
10. Conclusion
Citra requires AES keys to decrypt commercial 3DS games. These are stored in keys.txt. Users must legally dump them from their own console. Without correct keys, Citra cannot run encrypted game images. Extracting AES Keys : Users need to extract

2. Background: AES Encryption on 3DS
- The Nintendo 3DS uses AES-128-CTR encryption for most system software, ROMs, and save data.
- Each console has unique slot0x11Key (per-console key) and slot0x25Key (common key).
- To run encrypted games, an emulator must have these keys (but not the console-unique movable.sed).
4. How Citra Uses the Keys
When loading an encrypted ROM:
- Citra reads
keys.txtfrom the user directory (%appdata%/Citra/or~/.local/share/citra/). - It looks up the required key by slot number (e.g.,
