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.

6
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.

7
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.

8
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.

Button Mapping
Remapping the Buttons (continued)
4. Using the PS5 controller as the Src Label example and the PC Engine as the Dst Label example,
let’s say you wanted to change the PS5’s button to be the PC Engine’s button and the
PS5’s button to the PC Engine’s button. In the Dst Label column, select the drop down
next to the corresponding Src Label’s button you’d like to remap. In this case we’re going to
change the current button to be , change the current to being nothing, and setting the
currently empty drop down next to to . This essentially makes = and = .
5. Make sure to click the save button beneath the Mapping Cong section. The new button mapping
is immediately updated on the adapter once you click the save button.
Turbo Buttons (optional)
1. Let’s add some turbo buttons to and . Select the drop down next to in the Dst Label
column and set it to . Do the same for the drop down next to but set it to in the
Dst Label column.
2. Finally, set the turbo speed for and ( and ) by selecting a rate from the drop down.
The rate is based on the console’s controller polling rate which is most likely 60hz. Here’s a
few examples. Selecting “1/2 frames” pulses the button at 30Hz, so 1 frame on, 1 frame off.
Selecting “2/4 frames” pulses a button at 15Hz, so 2 frames on, 2 frames off.
Tip: For the original PC Engine / TurboGrafx-16 controller, the slow turbo is the equivalent of
“4/8 frames” and the fast turbo is “2/4 frames”.
3. Make sure to click the save button after any changes.

Updating the Firmware (OTA)
The PCE BT and Turbo BT adapters are rmware upgradeable via the Web Cong. The process is
very simple but takes around 10 minutes with a computer and much longer on a mobile device, so
we recommend using a computer for this process.
Downloading the rmware package
1. First, we’ll need to download the latest update rmware package from:
https://darthcloud.itch.io/blueretro
2. Click the “Download Now” button. A pop up will appear where you can either donate to Jacques
Gagnon, the creator of BlueRetro or click “No thanks, just take me to the downloads” to be taken
to the download page.
3. Select the latest rmware package with “HW1” in the name.
4. Once downloaded, unzip the package somewhere you’ll remember.
Flashing the OTA bin le
5. Connect to the Web Cong using the “Connecting to the Web Cong” section above for reference
and click the “BlueRetro OTA FW update” link within the Web Cong.
6. Click the button next to the “Select rmware” text and locate the unzipped rmware folder.
7. Inside the folder you should see several bin les but the one we want is called
“BlueRetro_pc_engine.bin”. Open the bin le.
8. Now click the “Update Firmware” button and allow the rmware to update. This typically takes
around 10 minutes on a PC and much longer on a mobile device.
9. Your adapter rmware is now updated.
