Pokemon Obsidian Emerald Version is a modernized all-doubles challenge hack of Pokemon Emerald Version from developers Skolgrahd and Speaker! This is our first rom hack, and we are truly excited to be able to say we finished what we set out to do: provide a fully playable PvE experience for lovers of VGC and competitive double battles.


  • All non-legendary, non-mythical Pokemon through Gen 8 available

  • Choose any starter from the first 8 generations

  • Updated Gen 9 battle engine with modern abilities, moves, typing, and mega evolution

  • GMax forms from Gen 8 are reincorporated as Megas

  • Gen 8 TMs and TRs are implemented and available, and can be used more than once

  • All Gym Leaders have a unique field effect, heightening the difficulty and giving the feeling that you are challenging the leaders on their home turf

  • To challenge a Gym, Pokemon League rules stipulate that the player must have no more Pokemon in their party than the Gym Leader does. No more unfair 6 vs 4 Gym battles!

  • The monotony of traveling from town to town has been replaced with grueling gauntlets, forcing you to battle many trainers consecutively to reach your destination

  • All the Kanto gym leaders appear in the overworld after Groudon is awoken, offering valuable prizes to those who manage to defeat them

  • hard level cap prevents overleveling and keeps the fights fair

  • Retooling and customizing your team is streamlined with exp candies, vitamins, nature mints, ability capsules and ability patches all available early on

  • Revamped feathers perfect a Pokemon’s IV in a given stat

  • EV berries remove 100 EVs

  • IVs and EVs are visible in the summary screen by pressing L and R, respectively (pressing start returns to the default view of the raw stats)

  • An optional Minimal Grinding Mode is fully implemented, causing the game to compute Pokemon stats as if they had 0 EVs and perfect IVs

  • Moves can be relearned from the party menu! Moves learned at level 1 still need to be relearned with the Fallarbor Move Tutor.

  • Field moves like HMs can be used by any Pokemon that can learn them, regardless of whether they actually know the move

  • The PokeVial from romhacks past is implemented, allowing healing without returning to the Pokemon Center

  • The PC can be accessed from the PokeNav, as long as you’re not in a gauntlet!

  • The PokeRadar allows chaining of Pokemon, increasing odds for perfect IVs, hidden abilities, and shinies, as well as applying a ramping exp multiplier for large streaks

  • The Exp Share has been modernized and implemented as a toggleable key item

  • Many Pokemon have received balance updates, including new types, abilities, base stats and learnsets, with more updates to come in future patches

  • Repels have been replaced with a toggleable key item, the PermaRepel



  • fixed the Pokedex+ ordering bug 
  • Fixed a potential crash when facing opponents with recovery options (like Norman’s Slaking with Drain Punch).
  • fixed a bug where Ability Capsule costs 100,000 and Milcery can evolve via level-up as well as by Sweet.
  • Fixed a critical bug that can crash your game when using field moves from the party menu
  • The TM Case update removes the TMs pocket from your bag, so you will not be able to see any TMs or HMs until you acquire an item in some way (buying a Poke Ball will work!), at which point the TM Case will be added to your Key Items pocket.


  • Cross Gen Evolutions from Gen IX are here! Welcome to Welcome to Obsidian Emerald, Annihilape, Dudunsparce, Farigiraf, Kingambit, Dipplin, Hydrapple and Archaludon!
  • All Pokémon movesets are properly updated to their most recent appearance in a mainline Pokémon game, including signature moves for Hisuian species.
  • The Battle AI has received some significant changes! Check out the Change Logs for specifics.
  • Candy Mode is now seperate from Minimal Grinding Mode, allowing access to the Infinite Candy in Oldale as well as causing NPC trainers’ mons to scale much faster after the level cap increases.
  • Many trainers have received updated parties! Those which have been updated have been given Poképastes in the Docs.


Systems Updates

  • Day time is from 12 PM to 11:59 PM » 8 AM to 7:59 PM
  • Night time is from 12 AM to 11:59 PM » 8 PM to 7:59 AM
  • Hisuian forms can now learn their signature moves!
  • Double battles with only one Pokémon in your party no longer crash the game. As such, the footprints man has been restored to his vanilla behavior (rather than preventing you from leaving Oldale Town until you’ve caught a second Pokémon) and the PC storage system and Day Care allow depositing your second-to-last combat-viable Pokémon.
