Bridge Steam Controller gyro and touchpad inputs to DSU-compatible emulators
Forward Steam Controller motion, touchpad, and button data into emulators by running a Cemuhook DSU server that exposes controllers as DSU slots. sc2dsu, from NightHammer1000, targets Steam Controller owners using desktop emulators and the DSU protocol. It offers a graphical interface for per-slot mapping and calibration, supports original and Triton/2026 models, and includes system-tray, portable, and headless operation options for local multiplayer and server setups.Forwards full Steam Controller input as DSU data
sc2dsu implements a Cemuhook DSU server that forwards motion, buttons, sticks, pads, and triggers to DSU-compatible clients, which means emulators that accept DSU connections can receive gyro and touchpad information from Steam Controllers. The app exposes connected controllers as up to four DSU slots, mapping each physical device to a distinct slot for local multiplayer use.
Manages connections and controller revisions without extra tooling
The app accepts Bluetooth, USB, and adapter connections, and explicitly supports both 2015 and 2026/Triton Steam Controller hardware revisions. Per-slot and per-MAC DSU subscriptions let the tool distinguish devices by MAC address, while axis swapping and inversion settings are available directly in the window, so you can adjust handedness and axis orientation without leaving the interface.
Offers configuration, calibration, and low-footprint operation
sc2dsu provides a GUI for configuration and live status reporting, plus built-in calibration controls for gyro and touch inputs. It includes system tray integration with start-minimized and close-to-tray options, a portable binary that needs no complex installer, and a headless mode for running on dedicated machines or servers where no interactive session is required.
Safety and emulator setup are explicit and local
The tool operates locally and exposes a DSU endpoint on the host, so emulator configuration typically points DSU settings at the loopback address and default DSU port. This local routing keeps traffic on the desktop and lets you run the emulator and the DSU server on the same machine for minimal network configuration.
Practical utility for Steam Controller users with a single caveat
sc2dsu suits players who need direct gyro and touchpad input routed into DSU-aware emulators, and it supports multiple controllers and hardware revisions while offering calibration and a portable option. A practical tip: configure your emulator to connect toand the DSU default port while the app runs on the same machine. Expect reliable local operation, though multi-machine networked setups need careful IP and port management.
