Configuration

DttR stores settings in dttr.json next to dttr.exe. Invalid JSON or a missing schema_major_version causes a configuration error.

If dttr.json is missing or empty, DttR uses the built-in defaults, creating the file only when it is missing.

Pass a config file to dttr.exe to use multiple persistent configurations:

dttr.exe custom_dttr.json

Set string fields to null to clear them. DttR treats unknown or mistyped scalar keys as configuration errors.

Gamepad Buttons (gamepad.buttons)

gamepad.buttons is a JSON object. Each key is the physical input you press, and each value is the game action DttR sends. When the object is present, omitted inputs are unbound, so include every binding you want to keep.

This example binds three inputs and leaves the rest unbound:

{
  "schema_major_version": 1,
  "gamepad": {
    "buttons": {
      "south": "joy_1",
      "east": "joy_2",
      "start": "joy_9"
    }
  }
}
