Install FSG on Steam Deck
FSG is a Decky Loader plugin. With DeckyHub installed, open DeckyHub's Discover tab in Gaming Mode, search for FSG and press Install. DeckyHub hands the release to Decky Loader's own installer and checks its SHA-256 whenever GitHub publishes one. You can also download the ZIP from its releases and install it by hand from Decky's developer settings.
Safety information
- No threats Virus scan of
FSG.zip(v0.4.0): ClamAV: no threats found; YARA: no threats found. A clean scan isn't proof of safety.
Security scans
Every ZIP DeckyHub offers is scanned with ClamAV and with YARA rules (YARA Forge's core set), and the same scans are shown in the app. VirusTotal and MetaDefender results are matched by the file's SHA-256, so the file itself is never uploaded.

| YARA | No threats found | November 2, 2026 |
| VirusTotal | Look this file up (by its SHA-256, nothing is uploaded) | |
