Radiata is a single Windows app. There is no separate runtime to install, no ads, no paywalls, and no account to make.

Complete Onboarding
A short guided setup checks your controller, verifies drivers, and then walks through usage, appearance, and configuration. You can re-run Onboarding any time from Settings ▸ Advanced ▸ Troubleshooting ▸ Run First-Run Setup.
Known Limitations
Hardware and Driver compatibility:
Unsupported Drivers: HP OMEN Gaming Hub, some Oculus or Virtual Desktop setups, and other vendor packages or controller-related apps can assert older versions of the same drivers. Radiata does not replace HP-supplied drivers, although they can interfere with Radiata's virtual controller. See driver conflicts in Help for what to check.
DualSense: Sony haptic triggers and touchpad will not be seen by games due to driver limitations, except in Passthru Mode.
Multiple Controllers: Input isolation can only support a single controller connected at a time. Radiata will function normally otherwise.
Extra-button pads (L4/R4): due to vendor hardware limitations, L4/R4 work natively over Bluetooth only. When wired, they can be seen if they're remapped.
Platform & requirements
Windows 10 or 11, 64-bit
Controllers
- If joy.cpl sees it, it should work. Hardware-tested with DInput, XInput, Bluetooth, USB, Wireless dongles, and first & third-party controllers.
- Xbox and XInput pads: Microsoft, GameSir, 8bitdo, and others work great with few limitations over wired or bluetooth.
- Sony and DInput pads: All the summon options of Microsoft pads, plus the option to use trackpad swipes if you want. DS Edge can use its dedicated Fn buttons.
More info
The Windows protected your PC alert
Microsoft SmartScreen warns about any program it has not seen many people run before. A new release from an indie dev like me starts from zero, so it gets flagged. The warning can eventually go away as more people run it.
Click More info and then the Run anyway button. If you would rather verify the source, Radiata is open source software: review the code or build it yourself from the GitHub repository.
HidHide and ViGEmBus
The first-run wizard offers to install two drivers, HidHide and ViGEmBus. Both are signed, open source, and widely used by other controller tools.
You can choose to decline them. If you do, you'll be locked into Passthru Mode, where the game keeps seeing your controller while a wheel is up. This kind of bleed-thru is annoying and not recommended. You can add the drivers later from Settings ▸ Advanced ▸ Install/Repair Drivers.
Uninstalling Radiata
Settings ▸ Advanced ▸ Uninstall Radiata removes the startup entry, the HidHide registration, and Radiata's own files. The shared drivers and your settings are separate, off-by-default opt-ins during uninstallation.
