Pokemon Crossroads GBA Rom Hack

• Author: xocolatiyo
• Hack Off: Emerald
• Language: English
• Released on: March 03, 2026
• Latest Version: Beta 1.3
• Last Updated: March 17, 2026

Pokemon Crossroads is a ROM hack of Pokemon Emerald developed by the Crossroads Dev Team.
It combines the regions of Hoenn, Kanto, and (in development) Johto into one seamless, epic adventure — the kind of ultimate Game Boy Advance experience Game Freak might have created if they had merged these regions back in the day.

Story

What if Game Freak had built the ultimate Game Boy Advance Pokémon adventure?

Pokemon Crossroads lets you step into the shoes of a young trainer journeying across not just Hoenn, but also Kanto and (coming soon) Johto — all connected seamlessly into one grand storyline.
Built on the powerful pokeemerald-expansion engine, we’ve integrated systems to bring these worlds to life authentically.

Key Features (For Beta 1)

• Three fully explorable regions: Hoenn, Kanto, and the Sevii Islands.
• Dual complete storylines: Play through the full stories of Pokémon Emerald and Pokémon FireRed — in any order you choose.
• 16 Gym Badges total (8 from Hoenn + 8 from Kanto), with a major surprise planned for Beta 2.0.

Known Issues

• Kanto badges do not appear on the Trainer Card yet
• Some FireRed-specific items are currently non-functional
• Trainer Card / other minor UI elements may behave differently depending on starting region

Recommended Emulators

• PC / Mac / Linux: mGBA (highly recommended — best accuracy and debugging)
• Android: Pizza Boy GBA, Lemuroid, or RetroArch (with mGBA core)
• iOS: Delta, RetroArch (with mGBA core), or Ignited
• Handhelds (Steam Deck, Anbernic, etc.): RetroArch with mGBA core

Current Progress

Development is moving steadily!

Completed core systems:

• Region switching: Seamless transitions between Hoenn, Kanto, and Johto with proper flag handling.
• Map integration: All major Kanto overworlds ported and functional with FireRed layouts and palettes.
• Multi-region minimaps: Each region displays its own map in the AreaNav with correct location names.
• Updated Fly system: Respects your current region and available landing points without cross-region bugs.

Current Focus: The team is currently porting events and scripts from Johto and Kanto into the Emerald engine, including:

• Gym/Event logic and story progression.
• Dialogue, cutscenes, and NPC routines.
• Custom map triggers and region-specific flags.

We are building custom tools to make this transition smoother, but it is a “heavy lift.” We are actively looking for scripters and event designers familiar with Gen III decompilation!

Planned Features:

Though we are in early development, planned highlights include:

• Four Explorable Regions: Hoenn, Kanto, Johto, and the Sevii Islands.
• Modern Battle Engine: Powered by pokeemerald-expansion (includes modern moves, abilities, and mechanics).
• Authentic Ports: FireRed-inspired regions using original maps and scripts.
• Quality of Life: Running indoors, reusable TMs, and more.
• New Warp System: Seamless travel transitions between regions.
• Native GBA Feel: Designed to feel like an official 2005-era remake.

Playthrough Tips

• Read in-game signs, NPCs, and any starter documentation for tips on region travel!
• Travel between regions: Use Pokémon Centers in Viridian City (Kanto) or Oldale Town (Hoenn)
• Report bugs on the GitHub Issues page or in our Discord small bugs channel.
• Enjoy the dual-story adventure — collect all 16 badges and uncover what’s next!
