How to Pair a Bluetooth Controller With Your Retro Handheld

A Bluetooth controller turns your retro handheld into a couch console. Plug the handheld into a TV, pair a controller, and you have a tidy little emulation box for the living room. A second controller also unlocks local co-op, which is where games like Streets of Rage and Bomberman truly shine. Pairing is usually simple, but the exact steps change depending on your firmware.

This guide covers how to pair a controller on the main firmware types, how to use a second controller for multiplayer, and how to fix the lag and dropouts that sometimes pop up. We frame all of this around playing games you already own.

Before You Start

Two things to check first. Make sure your handheld actually has Bluetooth, since some budget devices skip it. Then put your controller into pairing mode. Most controllers enter pairing mode by holding a specific button combination until the lights flash quickly. Check your controller's manual for the exact combo.

Popular controllers like the 8BitDo line, Xbox wireless controllers, and DualSense pads all work well with most handhelds.

Pairing on Android Handhelds

Android devices like the Retroid Pocket and AYN Odin make this easy.

1. Open the Android Settings app.
2. Go to the Bluetooth menu and turn Bluetooth on.
3. Put your controller in pairing mode.
4. Tap your controller when it appears in the list of available devices.
5. Wait for it to show as connected.

Once paired, the controller reconnects automatically next time. You may need to map its buttons in your emulator if the layout differs from the built-in controls.

Pairing on Linux Firmware

The steps are similar across muOS, KNULLI, ArkOS, AmberELEC, and Batocera, though menu names differ.

1. Open the main settings or system menu in your frontend.
2. Find the Bluetooth or Controllers section.
3. Choose to scan or search for devices.
4. Put your controller in pairing mode.
5. Select your controller from the list to pair it.

After pairing, you usually map the controller in the input or controller settings so the buttons line up with the emulators. Our firmware guides like the KNULLI setup guide and muOS setup guide cover where these menus live on each system.

Using a Second Controller for Local Co-op

Local multiplayer is one of the best reasons to pair controllers. Many retro games support two or more players on one screen.

1. Pair your first controller and confirm it works.
2. Put your second controller in pairing mode and pair it the same way.
3. In your emulator or frontend, assign the controllers to player 1 and player 2 in the input settings.
4. Launch a co-op game and test that each controller moves the right character.

For couch co-op on a TV, connect the handheld to a display first. Our best retro handhelds with HDMI out guide covers which devices output video. Then pair two controllers and you have a full living-room setup.

Fixing Lag and Connection Drops

Bluetooth is convenient, but it can add a little input lag or drop out. A few fixes help.

• Stay close. Bluetooth range is short. Keep the controller within a few feet of the handheld, with no walls in between.
• Avoid interference. Crowded WiFi and other wireless gear can interfere. Moving away from a busy router can help.
• Charge the controller. A low battery often causes dropouts. Charge it fully and test again.
• Re-pair if needed. If a controller acts up, remove it from the Bluetooth list and pair it fresh.
• Use a 2.4GHz dongle for less lag. Many controllers include a USB dongle that uses a low-latency 2.4GHz connection instead of Bluetooth. If your handheld has a USB port and your controller supports it, this often feels more responsive.
• Go wired for zero lag. For fighting games or anything timing-sensitive, a USB wired connection removes wireless lag entirely.

Picking a Controller

For retro gaming, a controller with a good D-pad matters more than anything. The

is a popular pick with an excellent D-pad and broad compatibility. For modern games and shooters, an pairs easily and feels great in the hands.
