Pokémon Fan Discovers Potential Fix for Pokémon Bank Shutdown

Last month, it was announced that Pokémon Bank will be shutting down in 2027. This 3DS storage app has served as a vital link between generations of Pokémon games, dating back to the Game Boy Advance era. While its relevance has diminished over the years, especially as players transitioned to the more centralized Pokémon Home, this closure signifies the end of a nostalgic chapter for many fans. However, one developer is working on a solution that could allow players to trade Pokémon between their Game Boy Advance and the Switch.

Andrew Henley, a software developer, has successfully created a prototype for a GBA-to-Switch adapter.

Trading Pokémon between an original GBA and a Switch 2 ????????

Still plenty of work ahead, but seeing a real GBA communicate and trade with the Switch is pretty incredible. #Pokemon #GBA #Switch2

Henley shared that this project began as a personal endeavor, driven by his desire to trade Pokémon from his original cartridge games to their Switch counterparts. A video he posted showcases a successful trade between the GBA versions of FireRed and LeafGreen and the Switch port released earlier this year.

“I found it fascinating to connect a Pokémon from an original Game Boy Advance cartridge with a modern system while maintaining that classic hardware experience,” he explained. “What started as a simple idea evolved into a technical challenge that I became passionate about solving.”

While backward compatibility is common in many systems today, the concept of linking a device as old as the Game Boy Advance with a Switch is ambitious. Henley noted that creating a seamless connection between these two devices was no easy feat.

“Nintendo designed robust communication systems for both the Game Boy Advance and the Switch, and understanding how they function and what each expects has been intriguing,” he said. “The real challenge lies in synchronizing two systems that were never meant to communicate, ensuring they can exchange data reliably in real time. It has involved extensive testing, debugging, and a lot of trial and error.”

Henley’s background in software spans various industries, including private sectors and government agencies, and he now runs a hospital compliance platform aimed at providing affordable systems for smaller and rural service providers. He’s applying this diverse experience to bridge the gap between two gaming devices separated by decades.

“At its core, the adapter acts as a translator between two systems that were never designed to work together,” he explained. “The Game Boy Advance expects to communicate with hardware from its own time, while the Switch operates on a different communication framework. My hardware and software facilitate this interaction in real time, allowing both sides to function normally without needing to understand each other’s systems.”

Currently, Henley is focused on connecting different generations of Pokémon games, but he envisions broader applications for the adapter in the future.

“A key aspect is that neither game is altered by this project,” he clarified. “The games continue to operate as intended, with the adapter simply facilitating communication between the two systems. It doesn’t need to interpret the data being exchanged; it just ensures the messages are relayed accurately.”

What began as a personal quest to trade his old Pokémon has evolved into a mission to enable older technology to interact with modern systems, which Henley believes is crucial.

“There’s a wealth of history tied to older hardware and software, and it’s valuable to find ways for these systems to continue interacting with newer technology without altering the original games.”

Henley aims to develop a production-ready version of the adapter but acknowledges that there’s still much work ahead before he can release a product he feels confident about. He envisions a “plug-and-play solution” for anyone wanting to connect their GBA to a Switch with minimal hassle. While he recognizes that Nintendo could create something similar, he understands that it may not be practical for them to invest in a niche accessory for a device that’s been out of production for two decades.

“I think it’s important to be fair to Nintendo,” he said. “They have a vast array of games and systems to support, and something this specialized may not be a priority for them. However, I can’t speak to their internal plans; you never know what they might be working on.”

For now, Henley is pursuing this as an independent project, with some assistance from the open-source community and experts in Pokémon homebrew and console communications, but without any official ties to Nintendo. He’s been encouraged by the growing interest from fans eager to trade Pokémon across generations, motivating him to refine the adapter into a more polished and user-friendly product. Those interested can follow his progress on social media.

Pokémon Bank is set to officially close on February 25, 2027, so if you want to transfer your old Pokémon to new hardware, it’s time to get started. The process is quite complex, and you have only a few months left to make it happen.
