Pokemon Mirage of Tales is a GBA Rom Hack by based on Pokemon Emerald.

Introduction
Avlar is a peaceful country with a long history that is known for its vast woodlands, rolling hills, and towering mountains. You take on the role of an orphaned eighteen-year-old who was fortunate enough to gain a scholarship to the Pokémon Trainer Academy in Umber Valley, a quaint little town in the Ore District.

It’s graduation day, and it’s time to take your final exam, get a job, and venture out into the big wide world with your Pokémon by your side. Which career path will you take? What kind of person are you going to be? It’s entirely up to you. Every choice you make has the potential to alter the course of your life.
Careers

You have the option of selecting your own trainer class if you so desire. Each profession has its own set of objectives, missions, and storyline branches. Choose wisely because you only have one chance!

Trainer
The “default” profession, you are automatically granted this title on the day of your graduation. You’ll have no boss to do things for and no HQ to report back to. If you’d like to play Mirage Of Tales the way you’d play a traditional Pokémon game, having freedom without constraints, this is the path best suited to you!

Rogue
Like Trainers, these lone criminals are their own bosses. Trainers can obtain the Rogue title by committing small crimes or tricking people into getting what they want.

Ranger
You have the option of joining the Avlar region’s widely respected Ranger Union. After your initial Academy-style training, your duties as a Pokémon Ranger will involve protecting endangered Pokémon, taking care of the environment, and helping those in need.

Researcher
Join Avlar’s Research team and become a Pokémon Researcher! You’ll be doing fieldwork or collecting all-important data for your Pokédex, and you’ll even be whisked away to exclusive unexplored areas.
