LegendCTL
A free, open-source (MIT), fully-local Windows app for configuring the ZD Ultimate Legend controller — deadzones, sensitivity curves, polling rate, button mapping, triggers, vibration, lighting, and profiles. It runs standalone (no official ZD app required), talks to the controller over USB-HID, makes zero network calls, and has no telemetry, drivers, macros, or background service.
