Pokemon Crossroads
HackPokemon Crossroads is an ambitious GBA ROM hack by Crossroads Dev Team that poses a compelling question: What if Game Freak had built the ultimate Game Boy Advance Pokémon adventure? Based on Pokémon Emerald and built on the powerful pokeemerald-expansion engine, this hack connects three regions—Hoenn, Kanto, and the Sevii Islands—into one seamless grand storyline. With both Hoenn and Kanto fully playable, all 16 badges available, and Johto in active development for a future release, Crossroads delivers an unprecedented multi-region experience on a single GBA cartridge.

About This Retro Game
Pokemon Crossroads represents a monumental achievement in ROM hacking: the successful integration of two complete Pokémon regions—Hoenn and Kanto—into a single, cohesive adventure built on the technical foundation of Emerald. Released in Beta 1.1 on March 3, 2026, the hack leverages the pokeemerald-expansion engine to create a stable, modernized foundation that supports seamless region travel, updated battle mechanics, and professional-quality presentation. The development team's vision extends beyond simply stitching maps together; they've crafted an experience where both regions feel organically connected, with their own完整 narratives, characters, and challenges coexisting within the same world.
The scope of content available in Beta 1.1 is staggering. Players can collect all 16 Gym Badges—eight from Hoenn and eight from Kanto—across two fully realized regions plus the Sevii Islands. The game respects the integrity of both original campaigns, allowing players to experience the complete story arcs of Pokémon Emerald and FireRed within a single playthrough. This dual storyline approach means encountering Team Aqua and Team Magma's schemes in Hoenn while later facing the challenges of Team Rocket in Kanto, all with a single team of Pokémon that can travel freely between regions.
A key innovation is the player's agency in choosing their starting point. Through dedicated patches, players can begin their journey either in Pallet Town (Kanto) or Littleroot Town (Hoenn). This choice fundamentally shapes the early game experience while ultimately converging into the same grand adventure. Region switching is instant and intuitive: simply visit the Pokémon Center in Viridian City (Kanto) or Oldale Town (Hoenn) to teleport between regions, with all progress, Pokémon, and items preserved seamlessly.
The technical implementation demonstrates the team's deep understanding of the Emerald engine. The AreaNav system has been expanded to include fully functional minimaps for each region, accurately tracking the player's position across Hoenn, Kanto, and the Sevii Islands. Built on the pokeemerald-expansion framework, the game benefits from modernized battle mechanics, improved stability, and enhanced features that bring the multi-region concept to life without compromising performance.
With Johto currently in active development for Beta 2.0, Pokemon Crossroads is poised to become one of the most comprehensive GBA Pokémon hacks ever created. The existing content—hundreds of hours of gameplay across two full regions and an archipelago—already delivers on the promise of an ultimate GBA Pokémon adventure. For players who have dreamed of a truly interconnected Pokémon world on the Game Boy Advance, Crossroads is the realization of that vision.
