Step 2: Create a Profile

Mappings are organized in profiles — create one profile per game.

  1. In the editor, the Mapping Profile selector is shown at the top of the window — use it to switch between profiles
  2. Click New and enter a name (e.g. the game name) to create a new profile
  3. Click Copy to duplicate an existing profile
  4. Switch between profiles anytime from the dropdown

Import an existing Profile

Instead of starting with a blank Profile, you can import a configuration shared by a friend or downloaded from the LaiCai community.

Import an existing Profile

  1. Prepare the Profile configuration file you want to import.
  2. Click Import in the Key Mapping editor.
  3. Select the configuration file, then click Open.
  4. When Import Success appears, click OK. The imported Profile keeps the mappings configured by its creator.
After importing, assign the Profile to the correct Android phone before its mappings can appear and take effect.

Part 2: Assign a Profile to a Phone

Profiles created in the editor are not automatically active. You need to assign one to each phone individually.
