Sudachi Prod Keys Guide
Sudachi is the minimalist member of the Yuzu family: a smaller feature surface, a light footprint and a setup that finishes in about a minute. It needs exactly the same thing as its relatives — one valid prod.keys file — so this page keeps the instructions short to match.
Download Prod Keys for Sudachi
One dump covers Sudachi and every other Switch emulator. The homepage download table carries v23.0.0 plus all older releases back to v16.1.0.
Where Sudachi Looks for Keys
Copy prod.keys into whichever destination matches your device, then relaunch Sudachi:
| Platform | Destination | Note |
|---|---|---|
| Windows | %APPDATA%/sudachi/keys/ |
Create the keys folder if it is missing |
| Linux | ~/.local/share/sudachi/keys/ |
Inherits permissions from your user profile |
| Android | Internal Storage/Sudachi/keys/ |
Relaunch the app once after copying |
Unlike Ryujinx, Sudachi has no separate system folder and no portable-mode variation — the path above is the only place it checks.
Sudachi Firmware Guide
Most commercial games require the matching Nintendo Switch firmware in addition to prod keys. Sudachi supports firmware versions 16.1.0 through v23.0.0. For detailed instructions, see our firmware guide.
Reading Sudachi’s Errors
Sudachi names the cause more precisely than most emulators, which makes triage quick:
- “encryption keys are missing” — the file is not where the table above says it should be; check for a doubled extension first
- “firmware not found” — keys are fine, firmware was never installed; see the firmware guide
- A single game fails to decrypt — the keys are older than that release, so refresh them from the homepage download table
