Playable On: Mobile, Pc, Emulator


A hack that allows you to get the "optimal experience" in the Yellow version. A lot of new stuff has been added, but Pokémon Opti-Y also retains some of the canons of the original game. So the gameplay of the modification has become fresh and retained the spirit of the first versions of the Pokémon series.

The need to trade for the evolution of the Pokemon has been removed. Some Pokémon evolve without exchange, others now evolve earlier than usual, even Pikachu evolves without the Electric Stone.

For optimal balance, the stats of many Pokémon have been reworked so that initially weak Pokémon can compete on an equal footing with others. For the same purpose, the types of some Pokémon have been updated. The changes also affected attacks: the developer added 23 new attacks, modified about 30 old ones, rewrote 19 existing ones in the Yellow TM version to more useful ones.

In the game Pokémon Opti-Y, the opposing teams have improved - the battles have become more difficult and interesting. Team Rocket members have a wider range of choices, so they are no longer limited to Zubats and Rattatas. Gym leaders and other bosses have become stronger: their teams have become more diverse, and individual Pokémon have their own movesets.

List of Features

  • All 151 obtainable: This seems to be a best-seller among this style of hacks lol. Some are available via in-game trades or other “special” means. Of course, every Pokémon can evolve to its final stage without the need to trade. Even your starter Pikachu evolves (by level). Some Pokémon evolve sooner. Wild Pokémon have been modified with an emphasis on variety. You can get useful Pokémon and varied teams from the beginning (without it being too broken). Check the documentation for full locations.
  • Optimization of Pokémon: A good chunk of the Pokémon had their stats boosted or rearranged and learn new and fitting moves/TMs. Some had their type changed for versatility (Kingler Water/ground, etc.), coolness factor (Ninetales Fire/Ghost, etc.), or just correcting what should have been done since the beginning (did you know Golduck wasn’t psychic? Yeah not anymore here). Keep in mind that this is only done for the sake of keeping the game more balanced and bringing Pokémon to their full potential, like Scyther learning decent moves. I’m not trying to break the game, no one had their stats boosted like crazy, except for the weakest ones like Farfetch’d or Porygon (which are decent now). Check the documentation for more on this.
  • New attacks / TMs / boosts to old moves:  23 moves from added (let’s say “replaced useless moves”) other gens to the game, as to have offensive bug/ghost/dragon attacks but also expanding the movepools of the Mons. Megahorn, Air Slash, Outrage, Brick Break, Sludge Bomb, Nasty Plot, Drill Run, Outrage. also edited 30 moves for balance. Egg Bomb is Grass, Gust is Flying, Rock Slide is more accurate, etc.19 of the TMs changed and most of the useful ones made available in stores.
  • More challenge: The opponents now have higher-leveled Pokémon and varied teams. I never understood why Team Rocket’s roster of Pokémon was pretty much only Zubat and Rattata, they steal Pokémon so they should have access to nearly everything. Also, no-more level 45 unevolved Pokémon, near the middle every opponent's Pokémon is evolved. The Boss battles are harder now, with them having more Pokémon, varied teams, and their own movesets.
  • Other quirks like: type match-ups now up to date (did you know the bug was weak to poison? Not any more now); new prizes at the Celadon Game Corner; new in-game trades; some items like PP Up being sold (at a high price)…
