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

A 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



Systems Updates

The party menu layout has been revamped!

Poké Radar chains confer 0/1/2/3/4/5/6 » 5/10/15/20/25/30/35 shiny rerolls.

The couple in Oldale Town will no longer trade Hisuian Zorua for Unovan Zorua and Hisuian Growlithe for Mightyena. Now, only one trade is available, and any Pokémon can be traded in return for a random Stage 1 Hisuian Pokémon (Growlithe, Voltorb, Qwilfish, Sneasel, Zorua or Sliggoo).

Eggs now hatch three times faster than in vanilla.

In Candy Mode, all bosses and trainers not in gauntlets have their Pokémons’ levels scaled up to a constant slightly below the current level cap » a constant slightly below the current level cap or two less than the player’s highest level Pokémon in party, whichever is lower, but never lower than two less than the previous level cap.

Items stolen through Thief and similar effects are no longer retained after Trainer battles.

Briney will no longer sail you to Slateport City before defeating Brawly.

Defeating your rival in Rustboro now grants an Ability Capsule.

Updated to pokeemerald-expansion v1.8.2.

Pokémon Changes

Bisharp – Does not appear in the wild » Appears on Route 123

Dragapult – Can be taught Shadow Claw.

Bug Fixes

Your Rival correctly bikes away instead of transforming into Brendan and quickly walking away after being defeated on Route 110.

A Magma Grunt in the Magma Hideout Gauntlet no longer fails to load a party.

Quash’s effect has been implemented.

Armor Tail, Dazzling and Queenly Majesty appropriately protect the partner Pokémon from opposing priority moves.

The Relearn Move option in the Party Menu now only appears if there is a valid move to be taught.

The weather on Route 119 no longer ceases after entering a building in the middle of the route and then returning to the route.

Fixed a bug where obtaining an item would cause some emulators to crash.

TM18 is no longer free.

Evolutions of Gen 1-8 Pokémon introduced in Gen 9 now have Pokédex+ entries. If you already have caught one of these Pokémon on your current save, you need to see or obtain them again to add the entry to your Pokédex, and the Pokédex+ party menu selection will still refer you to a blank page until you do so.

The level cap of 8 enforced before beating your rival on Route 103 now works as intended.


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.
