Web Cong
The PCE BT and Turbo BT allow you to customize and congure settings like 6 button mode, using
a mouse, button mapping, turbo, and multitap. To do this you will need to log into the Web Cong
of the adapter using Chrome on a computer or mobile device. No device should be paired to the
adapter while trying to access the Web Cong. A full technical guide for the Web Cong can be
found here: https://github.com/darthcloud/BlueRetro/wiki/BlueRetro-BLE-Web-Cong-User-Manual
Connecting to the Web Cong
1. If a device is paired to the adapter, short press the “P” button to disconnect it.
2. In Chrome, go to https://blueretro.io
3. The Web Cong has several links in the index but we only need to worry about the following:
BlueRetro Advance cong: Most of the conguration happens here.
BlueRetro Presets cong: This page is where you’ll set presets like mouse support.
BlueRetro OTA FW update: This is used to update the adapter’s Firmware.
4. Once you’ve clicked on the page you want to visit, click the “Connect BlueRetro” button.
5. A small window will pop up. Select the BlueRetro adapter name from the list of Bluetooth devices
and click “Pair”. If you get an error like “Argh! NetworkError”, repeat steps 1 - 4.

Pairing Devices
When you power on the PC Engine or TurboGrafx-16 with the PCE BT or Turbo BT plugged into the
controller port, the adapter will automatically be in “inquiry” mode with the LED pulsing, ready for
pairing either an already paired device or new and ready to be paired device.
Additional information can be found here:
https://github.com/darthcloud/BlueRetro/wiki/Controller-pairing-guide
Pairing Process
1. Power on the console with the adapter plugged in.
2. The LED on the adapter will pulse indicating it’s ready to pair with a device. If the LED is solid,
there is an error and you should press the “R” button on the adapter to reset it.
Note: If this is the rst time power on the device, there may be a 30 second delay in seeing the
LED pulse.
3. Put your device into pairing mode (use your device’s manual to nd out how to do this).
4. The LED on the adapter will turn off once the device is paired to it.
5. If you’re pairing the same device to the adapter on the next play session and you haven’t paired
the device to something else, then you should be able to simply turn on the device for it to pair
again to the adapter.

6 button Mode
In addition to the default 2 action buttons, the PCE BT and Turbo BT also support 6 buttons.
6 Button mode
1. Connect to the Web Cong using the “Connecting to the Web Cong” section above and use the
“BlueRetro Advanced Cong” link within the Web Cong.
2. Once connected, scroll down to the “Output Cong” section, click the “mode” drop down, and
select “GamePadAlt” from the list. Remember that “GamePad” is the setting you’d use when
you’re ready to go back to 2 Button mode.
3. Click the save button. A message stating, “Cong saved, power cycle BlueRetro adapter for Mode
change to take effect” will appear under the section.
4. Press the “R” button on the adapter. The adapter is now in 6 button mode and ready for a device
to be paired to it.
Some things to remember about the original hardware
• The PCE BT and Turbo BT are designed to mimic the original hardware. Any issues the original
hardware had with 6 button controllers will be present when using these adapters.
• Most games don’t support 6 button controllers and will cause input glitches in 6 button mode.
• 3 Button controllers were actually just 2 button controllers but with the ability to map the third
button to RUN or SELECT.
• 3 button games do not always support 6 button controllers and using 6 button mode with them
can cause input glitches.

Using a Bluetooth Mouse
The PCE BT and Turbo BT also support using a Bluetooth mouse. If using a ash cart, it’s
recommended that you launch the game with mouse support rst before switching to mouse mode.
Using a Mouse
1. Connect to the Web Cong using the “Connecting to the Web Cong” section above and use the
“BlueRetro Advanced Cong” link within the Web Cong.
2. Once connected, scroll down to the “Output Cong” section, click the “mode” drop down, and
select “Mouse” from the list.
3. Click the save button. A message stating, “Cong saved, power cycle BlueRetro adapter for Mode
change to take effect” will appear under the section.
4. Click the “index” link at the top of the page to return to the index.
5. Click the “BlueRetro Presets cong” link and follow the same connection instructions for the
Web Cong from the Web Cong section.
6. Once connected again, click the “select preset” drop down menu in the “Mapping Cong” section.
7. Select “Default Mouse” and then the save button.
8. Press the “R” button on the adapter. The adapter is now in mouse mode and ready for a Bluetooth
mouse to be paired to it.

9
Multitap Mode
The PCE BT and Turbo BT have an emulated Multitap mode that supports up to 5 controllers.
Note: When the Multitap mode is active, each connected device will mirror the rst device’s
conguration. For example, if the rst device is set to 6 button mode, each connected device will
also be in 6 button mode. The PCE BT and Turbo BT don’t support the original Multitap/Turbotap.
Setting up Multitap mode
1. Connect to the Web Cong using the “Connecting to the Web Cong” section above and use the
“BlueRetro Advanced Cong” link within the Web Cong.
2. Once connected, scroll down to the “Global Cong” section of the Advance cong. Next to
“Multitap”, click the drop down and select “Slot 1”. Click the “Save” button.
3. Press the “R” button on the adapter.
4. With the adapter in inquiry mode, pair your rst controller.
5. Once it’s connected, press and hold the “P” button on the adapter for a few seconds until the
LED starts to blink again. The adapter is now back into inquiry mode and the rst device is still
connected.
6. Put the next device into pairing mode and allow it to connect to the adapter.
7. Follow steps 5 and 6 to connect more devices.

Button Mapping
The PCE BT and Turbo BT have a robust button mapping feature that can be a little confusing at
rst but actually not difcult once you understand it. You will want to familiarize yourself with the
default mapping reference spreadsheet to help setup corresponding source and destination buttons:
https://tinyurl.com/bde43mbm
Remapping the Buttons
1. Connect to the Web Cong using the “Connecting to the Web Cong” section above and use the
“BlueRetro Advanced Cong” link within the Web Cong.
2. Once loaded, scroll down to the “Mapping Cong” section of the page.
3. You will notice there are quite a few drop downs in this area of the page. We’ll be focusing on the
following:
Src label: This represents the physical Bluetooth controller you want to use (i.e. PS4 / PS5).
Dst label: This represents the target controller (i.e. PC Engine).
Src: This column represents the various buttons from the source controller.
Dest: This column represents buttons from the destination controller.
Turbo: Speed settings based on frames if you want turbo on any given button.
