Product Description

Getting Started

Connect the power supply to the USB-C cable and the USB-C cable to Duo. Plug the power supply into a standard AC outlet. A dedicated SD card is required for game saves and full OS features.

Duo has two USB ports, which can connect and charge controllers as well as a miniDIN connector supporting original controllers and devices. Duo can connect with up to four Bluetooth controllers, two 8BitDo 2.4G controllers or two USB controllers. Up to four controllers can be connected simultaneously using any combination of connections. A fifth controller can be connected via the miniDIN or by  using an original Multitap device.

When first using Duo it will automatically search for a wireless controller to pair with indicated by a flashing white controller LED. Once a controller is paired or connected you can remotely power on Duo without having to press the Duo power button by simply powering on the controller (typically with the Start or Home button).

Use the included USB-C cable and Power Supply

Caution: Do not insert DVD, Blu-ray or damaged discs into Duo. These are not supported and may cause undesired behavior.

Upgrading Duo OS and Firmware

Zero Delay (60Hz) – Provides lag-free HDMI output. This mode will not work with 50Hz HDMI modes.

Fully Buffered – Buffers a full frame in order to maintain sync with the display’s native refresh rate (60Hz or 50Hz) and eliminates tearing.

Single Buffered – Buffers a portion of a frame with reduced latency relative to Fully Buffered mode, but will show a mismatched frame retrace line (tearing) visible once every several seconds.

Save States (coming in a future OS update)

Save States allow saving and loading virtually any moment of HuCard game play even if Duo has been powered off and on again. Past Save States are filtered by the game currently running. Create Save States by holding Home then pressing Up on the D-pad. With original controllers hold Up on the  D-pad then press Select.

Using Ten no Koe Bank ( Heavenly Voice Bank)

Originally, HuCard games could only save by implementing passwords. The CD- ROM² upgrade and later PCE Duo systems with a built in Super CD-ROM² added a dedicated 2KiB RAM for saving CD games and certain HuCard games. HuCard-only systems could still save to this memory by attaching a Ten no Koe 2 ((Heaven’s voice 2) or Backup Booster backup device.

Normally, games had to contend with other games for storage space within this 2KiB RAM. Analogue Duo provides an exclusive 2KiB to any game which accesses this RAM and will save backups of this RAM to SD card.

If you wish to use a Ten no Koe Bank ((Heaven’s voice bank) card to transfer backup RAM data from Analogue Duo to an original system, follow this procedure:

1. Insert the Ten no Koe Bank card in Duo, then Play Game followed by Quit Game.
2. Remove the SD Card from Duo, insert it into a PC or Mac and navigate to \Saves.
3.  Note the name given to the save file for the Ten no Koe Bank card and delete the file.
4. Find the save file of the game of the game you want to transfer to the Ten no Koe Bank card and rename the file to the filename given for the Ten no Koe Bank card.
5. Reinsert the SD card in Duo, play the Ten no Koe Bank card again and copy the Backup RAM to the Ten no Koe Bank card using the card’s built-in copying program.

Note that Ten no Koe Bank cards contain battery backed RAM and the original batteries may be expired preventing normal function.

Using Memory Base 128

Alternatively, Memory Base 128 has userreplaceable batteries, but unlike the Ten no Koe Bank card requires Super CD-ROM² or Arcade CD-ROM² enhanced systems on both ends of the transfer. The Memory Base 128 can backup the complete contents of the internal 2KiB save RAM.

The procedure is similar:

1. Find the name of the save file of the game whose save content you wish to transfer (“game 1”).
2. Find the name of the save file of the game which will perform the transfer (“game 2”).
3. Relocate the save file for game 2 temporarily and rename the game save of game 1 to the name of game 2.
4. Play game 2 and run its copying program.

Note that not all games may allow the transfer of the entire internal 2K backup memory to the Memory Base 128’s memory and may only allow their own games to be transferred. Private eye dol is one game which allows a full backup of the internal memory to be made.

Using Original System Cards

Analogue Duo supports original NEC System Cards as well as Games Express Green & Blue Cards. Supported features include CD audio, CD+G playback, and the original CD BIOS versions.

1. Insert the original System Card into the HuCard slot. If recognized, the OS menu will display “Using System Card”.
2. Insert and play the CD. The original System Card will be used automatically.

2. Put your controller in pairing mode by holding the pairing button.
3. Your controller will pair to Duo. Controller LED indicator will become solid when a controller is paired or wired controller connected to a USB port.
4. Pair additional controllers by repeating the above steps.

A 5th controller can be connected via the miniDIN or by using an original Multitap device. A controller connected via the miniDIN will always be assigned to Player 1. Duo does not support USB hubs as well as mixing a Multitap device with wireless or USB controllers.

8BitDo Bluetooth controllers need to be in X-Input mode before pairing.

8BitDo 2.4g controllers require specific firmware to work with Duo. This will disable compatibility with included original and USB controller port receivers unless reverted. The firmware update can be reverted by the same method indicated to update the firmware. Please visit support.8bitdo.com/analogue/Dock for firmware and instructions.

Force Disc Eject

Method 1: Unplug USB power from Duo along with any connected USB devices then plug power back in. Power on Duo while repeatedly pressing the CD eject button for 3-4 seconds to eject the disc.

Method 2: On the root of your SD card create a blank .txt file and name it “duo_eject.txt“ (case sensitive). Unplug USB power from Duo along with any connected USB devices. Insert the SD card with the new file. Plug in USB power and power on Duo to eject the disc automatically. If the disc does not eject on the first try please try again by repeating the above steps. Be sure to use the included USB-C cable and Power Supply. Delete the newly created file from the SD card before continuing to use Duo.

Factory Resetting Duo

Resetting will restore factory settings and erase all controller pairings from the Duo. Library and Memories will not be affected. Select and confirm “Global Reset” from OS menu Settings>Duo.

Manually Resetting Controller Pairings: Plug the USB-C power into Duo while holding the pairing button. Wait until the Controller LEDs begin to flash green and release the pairing button before the green LEDs turn off. If successful, all four Controller LEDs will flash red.

Controller Mappings
