Nintendo Switch Online Adds Enhanced Pokemon FireRed and LeafGreen with Advanced Telemetry Support

Nintendo has continued to expand its Nintendo Switch Online library, recently adding the beloved classics, Pokemon FireRed and Pokemon LeafGreen, to its catalog of playable Game Boy Advance titles.

Available through the service’s Expansion Pack tier, these releases reinforce Nintendo’s commitment to preserving its storied handheld legacy for a new generation of players on the Nintendo Switch. The debut of Pokemon FireRed and LeafGreen on Nintendo Switch Online marks an important milestone for fans and preservationists.

Developed originally by Game Freak and published by Nintendo, the titles were first released for the Game Boy Advance in 2004.

Now, nearly two decades later, players can experience these enhanced remakes of the original Pokemon Red and Blue adventures on modern hardware, further enriched by integration into Nintendo’s online ecosystem. In a significant technical discovery, dataminer @meatball_132 analyzed the code behind the new Switch releases.

Their investigation confirmed that the emulator powering Pokemon FireRed and LeafGreen is based on the same technology as the Nintendo Switch Online Game Boy Advance emulator.

Notably, this emulator is designed to send detailed telemetry data to Nintendo’s servers.

This data includes information on players’ in-game progress, such as which Pokémon have been caught and their respective levels.

Such telemetry allows Nintendo to better understand player interactions and improve future emulation experiences. The dataminer also reported that these ROMs are not simple ports; instead, they are newly created and feature heavily customized code revisions.

This suggests that Nintendo invested considerable resources in updating these games, ensuring smooth performance and compatibility on the Switch hardware.

Additionally, the emulator appears to incorporate emulation-specific adjustments—often referred to as ‘emulation hacks’—to support seamless gameplay and accurate reproduction of the original experience. Furthermore, @meatball_132 observed references to other titles within the emulator’s code, specifically mentioning Pokémon Ruby, Pokémon Sapphire, and Pokémon Emerald.

While these references do not confirm any future releases, their mention hints at a broader vision for the Nintendo Switch Online service, possibly paving the way for additional classic Pokémon games to join the platform. With Pokemon FireRed and LeafGreen now available on Nintendo Switch Online, Nintendo continues to leverage cutting-edge technology to breathe new life into its classic library.

Fans and newcomers alike can look forward to more enhanced and thoughtfully preserved gaming experiences as the company expands its digital offerings via the Switch eShop and the ongoing Nintendo Direct announcements.
