Play Pokemon Sienna (beta 3.1) Online
Explore the Sertia region, catch new Pokemon, challenge gym leaders, and tackle quests in this fan-made GBA adventure.
Pokemon Sienna (beta 3.1) is a fan-made game for the Game Boy Advance, released independently with no official publisher. It exists as a downloadable ROM, fitting right into the era of ambitious GBA homebrew projects that expanded on the classic Pokemon formula with new regions and stories.
You control a young trainer exploring the new region of Sertia, catching Pokemon and challenging eight gym leaders. The game introduces several new mechanics, including a day and night cycle that affects which Pokemon appear in certain areas, and a quest system with optional tasks that reward you with rare items. The pacing is deliberate, with a higher difficulty curve in trainer battles that requires more strategic team building than the official games. It feels like playing a thoughtful, handcrafted extension of the adventures you remember.
