4. Operating Instructions
4.1 Turbo (Auto-Fire) Function Customization
The adapter supports a customizable Turbo function for up to eight buttons. Follow these steps to set or cancel auto-fire:
- Press and hold the 'TURBO' switch button located on the adapter.
- While holding the 'TURBO' button, press the specific button on your PS1/PS2 controller that you wish to customize for auto-fire.
- Release the 'TURBO' switch button on the adapter, but continue to hold the button on your PS1/PS2 controller. The LED indicator on the adapter will light up, confirming that the Turbo function has been successfully assigned to that button.
- To cancel the Turbo function for a specific button, repeat steps 1-3. The LED will turn off, indicating the function is deactivated.
All Turbo settings are temporary and will be automatically deleted when the adapter is unplugged from your Wii Remote.
4.2 Default Button Mapping
The adapter maps PS1/PS2 controller inputs to the Wii Classic Controller layout. Below is a general mapping:
| PS1/PS2 Controller | Wii Classic Controller |
|---|---|
| Start | + |
| Select | - |
| D-Pad | D-Pad |
| Left Analog Stick | Left Analog Stick |
| Right Analog Stick | Right Analog Stick |
| X Button | B Button |
| O Button | A Button |
| Square Button | Y Button |
| Triangle Button | X Button |
| R1 | ZR |
| R2 | R |
| L1 | ZL |
| L2 | L |
| L3 (Left Analog Stick Press) | Home |
| R3 (Right Analog Stick Press) | Home |
Note: Some users have reported that the R3 button also functions as the Home button, which may lead to unintended actions in certain games. Additionally, the mapping of shoulder buttons (L1/R1 and L2/R2) might vary slightly from the expected Classic Controller layout in some instances.
5. Compatibility
- Consoles: Nintendo Wii, Nintendo Wii U.
- Controllers: Compatible with official PS1 and PS2 DualShock controllers. Compatibility with third-party PS1/PS2 controllers and specialized peripherals (e.g., arcade sticks, dance pads) may vary.
- Games: Works with Wii and Wii U games that support the Wii Classic Controller. This includes many Virtual Console titles (NES, SNES, Turbografx ports) and specific Wii games.
- Limitations:
- Vibration feedback is not supported through this adapter.
- This adapter does not enable PS1/PS2 controllers to play Nintendo GameCube disc games via the Wii's GameCube controller ports. GameCube games require GameCube controllers plugged directly into the console's dedicated ports.
6. Troubleshooting
- Adapter Not Responding:
- Ensure both the PS1/PS2 controller and the adapter are securely connected.
- Verify the adapter is firmly plugged into the Wii Remote's expansion port.
- Try unplugging and re-plugging all connections.
- Test with a different PS1/PS2 controller if available, to rule out controller issues.
- Incorrect Button Mapping:
- Refer to the 'Default Button Mapping' section (4.2) to understand the expected layout.
- Some games may offer in-game controller remapping options. Check the game's settings.
- Be aware of the reported R3 button acting as Home, and potential shoulder button discrepancies.
- Turbo Function Not Working:
- Ensure you are following the customization steps precisely (Section 4.1).
- Confirm the LED indicator on the adapter lights up when setting the Turbo function.
- Remember that Turbo settings are reset when the adapter is unplugged.
- No Vibration:
- The MAYFLASH W004 adapter does not support vibration feedback. This is normal operation.
