Pokemon Emerald Rule-ette ROM

Emerald Rule-ette is a Pokémon Rom Hack of Pokémon Emerald, keeping the vanilla story, but adding a new twist. For each trainer battle, random battle rules are rolled. Violation of a rule will lead to penalization in the form of a reduction in HP, forcing the player to adapt on the go and play around it. The USP of this game is the Battle Rule System where some rules alter the battlefield itself, such as permanent Trick Room, Inverse Battles, Truant, or Perish Count.

Others are hidden conditions that punish specific actions, forcing you to identify and adapt to the rule during battle. The hack was originally designed with Nuzlocke players in mind and includes a fully integrated Nuzlocke mode featuring Permadeath, No Bag in Battle, Dupe Clause, Met Location Clause, automatic encounter validation, and numerous tools that remove tedious grinding while preserving the challenge.
