Pokémon Bank is scheduled to shut down on 25 February 2027, ending the 3DS app’s long role as a bridge between Pokémon games. It once helped players move creatures from Game Boy Advance-era releases into newer generations, although its role is now much narrower alongside the platform-independent Pokémon Home.
One independent developer is exploring a different way forward: a hardware and software adapter that lets an original Game Boy Advance communicate with a Switch 2.
A working GBA-to-Switch prototype
Software developer Andrew Henley has demonstrated a functioning prototype after beginning the project as a personal challenge. His aim was to trade Pokémon between original cartridge games and their modern Switch releases.
The demonstration shows Pokémon being traded between the Game Boy Advance versions of FireRed and LeafGreen and the Switch port released by Game Freak earlier in 2026. Henley shared the result on 3 September 2026.
Henley says the idea came from wanting to preserve the experience of using an original cartridge while allowing its Pokémon to interact with a modern system. What began as a personal transfer project developed into a substantial technical problem.
Translating two very different systems
The Game Boy Advance and Switch were never designed to communicate with each other. Henley’s adapter sits between them, translating their communication in real time so both consoles can continue operating as though they were connected to hardware from their own generation.
That process has involved extensive testing, debugging and trial and error. Although both systems have robust communication methods, they expect different behaviours and must remain synchronised during the exchange.
Importantly, the project does not modify either game. The original software continues to run normally, while the bridge carries the communication across in the format each side understands. Most of the exchanged data can remain opaque to the adapter; it only needs to interpret enough of each system’s communication method to relay the message accurately.
The concept reflects a broader preservation issue familiar to readers of RETROCADE’s arcade news: older hardware contains substantial cultural and technical history, but that history can become difficult to access as platforms age.
More than a Pokémon project?
For now, Henley is concentrating on connecting different generations of Pokémon games. However, he describes the design as being built around interoperability, leaving open the possibility of other uses beyond Pokémon trading.
His professional background spans software work in private industry and government, as well as developing a hospital compliance platform intended to make systems more affordable for smaller and rural providers. He has applied that experience to the problem of connecting two gaming devices separated by decades.
The project also draws on open-source research and homebrew expertise from Pokémon and console-communications specialists Yannik and Tornadus11. It has no official Nintendo affiliation or endorsement.
Will the adapter become a finished product?
Henley hopes to develop a production-ready version that is effectively plug and play, with minimal setup for people connecting a GBA to a Switch console. He acknowledges that considerable work remains before he would feel comfortable releasing it publicly.
He also notes that Nintendo would be better placed to manufacture an official version, but a specialised accessory for a roughly 20-year-old system that is no longer produced may not be a practical priority. Nintendo already supports a large catalogue of games, consoles and services, although Henley says future official support cannot be ruled out.
Growing interest from players who want to move Pokémon across generations has encouraged him to make the project more polished and accessible. Progress is being shared through Twitter and Bluesky.
What Pokémon players can do now
Pokémon Bank’s closure is still scheduled for 25 February 2027. Anyone planning to move Pokémon from older games should not assume this experimental adapter will be available in time. The existing transfer process is complicated, and the remaining window is limited.
For enthusiasts interested in preserving and connecting older technology, the project is a reminder that thoughtful hardware design can extend the useful life of legacy systems. Similar hands-on experimentation sits at the heart of DIY arcade projects, while practical restoration work often depends on reliable arcade parts.
