You are the only trainer in Hoenn that can level up. Your objective is to beat every trainer, but if you lose, you start from your hometown again. You only get to keep your team and bag.

Every battle is a double battle. Espeon+Umbreon starter (or two Eevees). Follower Pokémons.

Built on top of Emerald Legacy.

There's:

massively diversified trainer teams
special trainers from other regions
dynamic level scaling
extensive quality-of-life improvements, including all pokemon available, stats editor, and special NPCs across the region

Talk to Mom in Littleroot Town. She explains the rules and activates/deactivates the mode.

Play it here (with pokédex!) or at Hackdex.
