FBI is the title manager that reads QR codes. After hacking your 3DS, FBI is usually installed automatically. If not, install the FBI .cia via the standard method first.

Traditionally, installing homebrew applications on a 3DS involved downloading a .cia file, placing it on your SD card using a computer, and then installing it via FBI (a homebrew title manager). While effective, this process has two major flaws:
QR codes solve this problem entirely.
The FBI application (which you should already have if your 3DS is homebrewed) includes a "Remote Install" feature. By scanning a QR code, FBI will:
No PC. No SD card reader. No file renaming. Just point, scan, click, and play.
Because QR codes change with updates, use one of these trusted sources: snes9x 3ds qr code
⚠️ Don’t scan random QR codes from unverified sources — they could install malicious software.
Even with QR codes, things can go wrong. Here’s how to fix them.
| Problem | Solution |
| :--- | :--- |
| "Failed to install from URL" | The QR code URL is dead or the server is down. Generate a fresh QR code from the official GitHub release page. |
| QR code scans, but nothing downloads | Your 3DS Wi-Fi is unstable. Go to System Settings → Internet Settings → Test Connection. Ensure you aren't using a public Wi-Fi with a login portal. |
| SNES9x crashes on launch | You are on an Old 3DS with an outdated version. Download the snes9x_3ds_old.cia (Old 3DS optimized) via QR code instead. |
| ROMs don't appear in the menu | ROMs must be in sdmc:/snes9x/roms/. Case-sensitive. Ensure the folder exists and ROMs are unzipped (.zip files are not supported; extract them first). |
| Sound is crackling | Turn on Sync to Audio in the in-game menu, or lower the Audio Quality from 32kHz to 22kHz. | FBI is the title manager that reads QR codes
