Quick start

01

Bring your own ROM

A legally obtained Pokémon Emerald (USA). It is patched in your browser and never uploaded: the game stays on your device.

02

Get your partner

Create a room and share the code to play with another player, or just add them in the friendlist and invite them. Once you are both in, you can start playing.

03

Start your adventure

Interact with your PC to start your adventure. Every time you load into a new game the random seed shuffles things up.

A world of features

And much more to discover!

CHARACTER SKINS

Unlock trainers' skins and show the world who you are. The skin will be displayed both in the game and in the profile card.

NOT EVERYTHING IS LOST

Several NPCs will offer to help you in different ways, and some of them can store items and currency for you to use in next runs.

EGG SYSTEM

Upon reaching certain milestones, you will find eggs of various types that will hatch after defeating a set number of trainers in battle, once put in an incubator. You can purchase additional incubators in your profile with Money stored in the vault.
