About This ROM Hack

Pokémon Emerald Coin Toss is a complete battle-system overhaul that removes traditional strategy and replaces it with pure randomness. Every Pokémon in the game can only learn one move: Coin Flip.

This hack turns Hoenn into a probability simulator where every fight — from early Route battles to the Champion — becomes a simple 50/50 outcome.


Key Features

  • Single Move Gameplay: All Pokémon only learn Coin Flip through level up.
  • 50% Accurate OHKO Move: Coin Flip has 50% accuracy and instantly knocks out the target if it lands.
  • Unnegatable Knockouts: The one-hit KO effect cannot be prevented by abilities, items, or battle conditions.
  • Fixed Accuracy Rules: Accuracy cannot be raised or lowered, ensuring the move always remains a true 50% chance.
  • 50% Priority Chance: The Pokémon using Coin Flip has a 50% chance to move first regardless of Speed stats.
  • All Other Moves Disabled: Any move besides Coin Flip has no effect in battle.
  • Struggle Replacement: Struggle has been replaced with Coin Flip, preventing any alternative damage sources.
  • Pure Chance Battles: Every encounter becomes a straightforward game of probability with no strategic depth.
