Pokémon Emerald Seaglass

What it is

Pokémon Emerald Seaglass keeps the Hoenn adventure but gives it a new look: every graphic has been redrawn in a soft, GBC-flavoured style, with new overworld sprites for the player, Team Aqua, Team Magma and many other characters, recoloured battle backgrounds and a new title screen.

What's new

• All Pokémon from the first three generations can be caught, plus cross-generation evolutions such as Roserade and Mamoswine
• Reworked versions of weaker Pokémon, with new types and moves to make them worth using
• A battle engine updated to modern rules, including the physical/special split and the Fairy type
• New minigames, among them scuba diving and pinball, and a Wishing Well in Rustboro City that trades Wishing Stars for random Pokémon
• Every Legendary obtainable, quality-of-life improvements and an optional Hard Mode
