Diancie (Mega) in Inclement Emerald

Rock / Fairy — where to catch it, what it learns, and how it differs from the official games.

Compared with the official games

Against the base species it is built from:

Stats Attack 100 → 160, Defense 150 → 110, Sp. Atk 100 → 160, Sp. Def 150 → 110, Speed 50 → 110 (total 600 → 700)
Abilities gains Magic Bounce and loses Clear Body

Compared against present-day official data. The Fairy type and hidden abilities arrived after Pokémon Emerald, so a difference here can belong to the series rather than to this hack.
