About This ROM Hack

Pokémon Omega Ruby (GBA) is a mechanics-focused enhancement hack of Pokémon Ruby that keeps the original Hoenn journey fully intact while introducing modern transformation mechanics like Mega Evolutions and Primal Reversions.

Instead of changing the story or redesigning the region, this hack focuses on making classic Ruby feel more powerful and modern by integrating evolution systems that normally belong to later generations.

The main idea is simple: keep Hoenn unchanged, but upgrade how Pokémon evolve and battle.

The story remains completely identical to Pokémon RubyThe only difference is how Pokémon evolve and transform during gameplay, not the narrative itself.
