Solar Emulator
Keyboard and Mouse to Controller Emulation
Solar Emulator lets you play with a keyboard and mouse while sending controller input to the game. It is designed as a game-independent emulator for titles that accept controller input. Controller-specific behavior, including aim assist, depends on what each game provides.
Map keyboard and mouse inputs to controller controls in the layout you prefer. Multiple keys can share the same controller mapping, and the input settings can be tuned to suit different sensitivities and playstyles.
Control How Emulation Behaves
Adjust horizontal and vertical sensitivity, movement output, stick behavior, and fast mouse movements. Solar also lets you choose whether unmapped inputs reach the game, so you can configure input pass-through for games that allow a mix of keyboard, mouse, and controller controls.
Custom pass-through rules let you temporarily leave emulation and return with your chosen keybinds and activation behavior. Save multiple configs, import or export them, and select one to load automatically.
An RP board is required to use Solar Emulator.
Features
Engine and Input
- Engine Toggle — turn keyboard-and-mouse to controller emulation on or off from the interface or a custom keybind.
- Controller Mappings — map keyboard and mouse inputs to every controller control. Assign multiple keys to the same controller input.
- Block Unmapped Inputs — choose how unmapped keyboard and mouse inputs are handled:
- Off — unmapped inputs pass through to the game.
- Special Keys Only — blocks special key inputs, such as Alt+Tab.
- All — blocks all unmapped inputs.
- Notifications — select notifications for engine changes and pass-through activity.
Mouse and Stick Tuning
- Horizontal and Vertical Sensitivity — tune each axis independently.
- Full Stick Mouse Speed — adjust mouse speed at full stick output.
- Minimum Moving Output — adjust the minimum output while moving.
- Right Stick Direction — invert horizontal or vertical movement.
- Stick Drift — enable simulated drift and adjust its strength.
- Fast Movements — tune large mouse movements with Fast Movement Boost, Boost Start, and Motion Averaging.
Left Stick Movement
- Humanize Movement — adjust the transition time for left stick movement.
Pass-Through
Use custom rules to temporarily stop emulation and switch back to keyboard and mouse, then return to emulation.
- Enter Pass-Through — choose a custom keybind and an Instant, Hold, Double Tap, or Triple Tap activation.
- Return to Emulation — choose a custom keybind with Instant or Hold activation. A Block Return Key option is also available.
Configs
- Config List — save multiple configs, rename or delete them, and import or export them.
- Auto Load — choose a config to load automatically.
Requirements
Required Hardware
- RP board — required for Solar Emulator. See this RP board listing.
- Keyboard and mouse — the input devices used for controller emulation.
Game Input
The game must accept controller input for Solar Emulator's controller output to be usable. Features such as aim assist depend on the game.
