Final Note

Win a
Medal 🏅

Kanto is reborn with Mega Evolutions and Z Moves, up to 8th Gen, high difficulty and day/night system. Explore mysterious portals with Ash and Pikachu in this GBA Hack ROM.

✨ Super Effective (Pros).

Expanded combat mechanics: Incorporates Mega Evolutions and Z-Moves in Kanto, revitalizing the experience.
Variety of Pokémon: Access to creatures from the 1st to the 8th generation, with the option to randomize for greater replayability.
Improvements in gameplay and difficulty: Day/Night system, increased difficulty and new mysterious portals that invite you to explore.

🔻 Not very effective.... (Cons)

Limited content: Currently in beta phase, available only until the third gym.
Lack of narrative originality: Despite the new story, it reuses Kanto with Ash, Pikachu and Team Rocket as classic protagonists/antagonists.
Language barrier: Available in English only, which may limit its reach to a wider audience.
