You can turn a Game Boy Advance into a Bluetooth gamepad, but this is a DIY electronics project—not a plug-and-play adapter. It uses an ESP32 connected to the handheld’s link port, plus custom hardware and firmware. The project pages describe different handheld compatibility: the original Shyri design is for a standard GBA, while giltesa’s adaptation is described as supporting a GBA or GBA SP.
How the GBA Bluetooth gamepad works
The project connects an ESP32 to the Game Boy Advance’s link port. In Shyri’s original design, with no cartridge inserted, the ESP32 sends a small ROM to the GBA at startup. The handheld then communicates with the ESP32, which forwards button input as a Bluetooth HID gamepad. Shyri’s README says the ESP32 draws 3.3 V from the link port.
Giltesa adapted the concept around the shell and connector from a GBA Wireless Adapter, and provides board files, documentation, and a compiled firmware image. The image still has to be flashed onto the ESP32.
Which GBA models and Bluetooth hosts are described?
| Project | Handheld compatibility stated by its maintainer | Connection and setup notes |
|---|---|---|
| Shyri’s original project | Traditional/original Game Boy Advance; the README says it does not work with the GBA SP. | ESP32 connects at the link port. The README names a PC, phone, and Android TV as example Bluetooth hosts. |
| Giltesa’s adaptation | GBA or GBA SP, according to the README and shop listing, using a GBA Wireless Adapter shell and connector. | Includes board files and a compiled image, but the ESP32 still needs to be flashed. |
These are project-maintainer descriptions, not independent compatibility tests. The documentation does not publish a complete host, operating-system, or emulator compatibility matrix, so do not assume every Bluetooth device will accept it.

#1 Best Overall
- Compatible with Nintendo GBA, GBA SP and for GameCube.
- Compatible with Nintendo Wii with GC Port only ( Not for Wii U).
- Only Work for Specific Designed Game allows you to connect the GBA or GBA SP for GameCube or Wii.
- Connect your GBA/GBA SP for GameCube Controller Port.
- The pictures are accurate because of real shooting, please check it carefully to make sure it is what you need.
What you need to build it
Giltesa’s adapted design lists these components:
- GBA Wireless Adapter shell and connector
- Custom 1 mm PCB, ordered from the project’s Gerber files
- ESP-WROOM-32 ESP32-WROOM-NARROW module
- One 1K and two 10K 0603 resistors
- One 0603 LED
- Two 4.6 × 2.8 mm bottom switches
- USB UART-CP2102 programming adapter
Check the project board files for the exact module fit before sourcing parts. The list identifies the components, but does not establish stock at any particular retailer.
Build and pairing considerations
Expect to assemble the hardware and work with ESP32 development tools. Giltesa says flashing can be difficult for people unfamiliar with those tools; the supplied compiled image and instructions are intended to reduce that burden, not remove the need to flash the board.

- 【OLED Display and Effortless Device Information Access】 The screen simplifies pairing the Microsoft Xbox wireless adapter with all Bluetooth headphones, earbuds. It can intuitively display volume, codec format, mic status, and paired Bluetooth devices.⚠️ Important Pairing Tip:Pairing requires holding both Vol+ & Vol- simultaneously until "Searching" appears.
- 【aptX Low Latency】The codec ensures synchronized audio, stepping you into the world of wireless gaming with our Xbox One Bluetooth adapter. Low latency requires your headphones to also support this technology.
- 【Wide Compatibility】The Xbox audio adapter is designed for Xbox One, Series X, Series S, and Elite Series 2 Wireless Controllers with 3.5mm audio jack. It does not support the first-generation Xbox controller and the Elite 1 controller.
- 【Upgraded Tech】Powered directly by the controller, the Xbox headset adapter delivers low energy consumption. It further conserves power by automatically dimming the screen after 10 seconds of inactivity. This design is enhanced by two indicator lights, giving quick feedback on the adapter and mic status.
- 【Note】Even after the transmitter is powered off, the mic remains active when the mute switch is leftward. Sliding it right activates the mute indicator light, disabling the mic. The mic can function independently without paired headphones. Additionally, the adapter doesn't support the microphone of Bluetooth headhones.
Shyri’s README describes putting the Bluetooth module into discoverable mode for pairing. After pairing, the device address is retained for a later reconnect. The documentation gives no measured latency, wireless range, battery-runtime figures, or host-by-host setup instructions.
Is it a ready-made product?
No assembled controller is established by the linked shop listing. It labels the item a free downloadable product and says nothing physical is included; components are not included either. Treat it as project files and instructions for a build, not as a finished adapter you can plug into a GBA.

Which project should you follow?
Choose based on the hardware you have and the specific project’s stated compatibility. If you have a standard GBA, Shyri’s original project explicitly names that model. If you want to attempt a GBA SP build, giltesa’s adaptation is the one whose documentation describes GBA or GBA SP support. Neither source provides independent testing or a broad compatibility guarantee.
The two repositories are distinct releases with different licenses: Shyri’s repository is GPL-3.0, while giltesa’s states CC BY-NC-SA 4.0. Giltesa credits Shyri with the original idea and software.
