Pokemon Odyssey GBA Pokemon ROM Hack Game Boy Advance

This is a crossover project between  Pokémon, Made in Abyss, and Etrian Odyssey. It’s a sort of dungeon-crawler story-driven, but you don’t need to know anything about Etrian Odyssey or Made in Abyss to fully enjoy this game!

Synopsis

On the island of Talrega lies the entrance to the Yggdrasil labyrinth, a gigantic desert carved from the roots of the tree of life over millennia; filled with treasures and other valuable items, it attracted explorers from everywhere. 
What are you looking for? Fame? Money? Or do you just want to test your coaching skills by tackling the maze? Is there something deep down?
In this game, you’ll play as Nyx, a young adventurer who wants to challenge the labyrinth. 
But as soon as she starts descending, something goes wrong…
