Description

Pokemon Lucid is a difficulty hack of Emerald, built using the Emerald expansion engine to bring all Pokémon into Gen 3. The game features Pokémon up to Generation 9, tough opponents, enhanced AI, and a variety of modern mechanics and quality-of-life improvements for a fresh gameplay experience.

Features

• Pokemon from Gen1-9
• Updated Battle Mechanics (Gen9) with a few exceptions
• Heart Gold / Soul Silver style dex
• Platinum style summary screen
• Multiple chracters to choose from (Red, Leaf, Ethan, Kris, Lyra)
• Built in hard Level Caps
• New locations that allow temporary use of Terastallization to advance to the story! Tera Island and Stella Island
• Other gimmicks, only on Casual Mode: Mega, Z-Moves or Tera outside the Islands
• Hoenn progression has been reworked alongside a simplified story with new bosses, including a brand new E4

Quality Of Life Changes

Since the primary focus of this hack are trainer battles, a lot of qol changes were made to remove distractions and streamline the gameplay.

• Porta-PC
• Poke Vial
• Poke Rider (replacement for HM Fly)
• HMs have been replaced by story check points (noteable: surfing is unlocked after badge 5)
• Permanent Repel
• Level Cap candy (levels up to the level cap)
• Easy access to many tutor moves
• Pre-damaging and pre-statusing in party menu
• Instant Egg Hatching
• Infinite money
• Running shoes can be toggled to be permanent
• No grinding, levels are increased with the Level Cap Key Item

Game Modes

The project has 2 modes, a Normal Mode and a Casual Mode. Both modes have the same trainer battles, but in Casual Mode you can build your own adventure. What is meant by your own adventure? In a new game, if the option Casual Mode is chosen, access to a newly added house south of Littleroot Town will be granted. This place has a lot of settings to customize the game. That includes choosing a gimmick (Mega, Tera outside the Tera Islands, or Z-Moves) and access to a lot of powerful items. Basically, Casual Mode provides the player with many more tools to play the game.

Randomizer Options

• Scaled Randomizer: The quality of encounters scales with progress made
• Normal Randomizer: Regular randomizer where anything can be encountered

Known Issues

• Battle Engine
  
  • If both attacker and target have Eject Pack and Eject Button
    
    • In Lucid the activation is based on speed
    • In vanilla Eject Button always activates before Eject Pack
  • Mirror Coat and Counter don’t work in double battles (inconsistent)
• Battle AI
  
  • Hone Claws is a fake move. The ai never considers it.
• Trainer Mon Ursaluna from Santiago has Bulletproof instead of Guts

Changelog

V1.2.12

• Bugfixes

  • Fixes Wandering Spirit activation preventing Eject Button if the copied ability was triggered
  • Fixes Echoed Voice damage calc during switch in (If a move other then EV was used more then once in a row, EV was seen as boosted dmg during switch in)
  • Fixes Octlock not ending when user of move switches out or faints
  • Fixes timing issue with Eject Pack and Intimidate. Eject Pack is supposed to trigger after all abilities activated. Then the fastest Eject Pack activates
  • Fixes mon taking Life Orb damage if it was switched in due to Eject Pack

• Other

  • Added utility option to toggle healthbox type icons in battle

V1.2.11

• Fixes Future Sight calculation with mon in the front instead of the back (this was a regression again from a previous release, sorry)

V1.2.10

Fixes

• Freeze in 2v1 battles when right side trainer had no mons to switch in, while left side trainer was about to switch in a new mon
• Spread move bug in doubles when right slot mon was supposed to defrost. E.g Heat Wave hit could only defrost the right side slot (player POV)
• Life Orb damage reduction when mon couldn’t move due to flinching
• Choice Lock timing when mon was unable to use a move (e.g. due to Fake Out)
• Wandering Spirit copied ability activating on fainted mon (e.g. copied Intimidate activated on fainted mon)
• Wrongly applied calculation order (stat stages should always apply first)
• Choloroblast taking damage when the move failed. Chloroblast previously used the Steel Beam effect but the moves are slighlty different
• Mortal Spin trying to poison a mon that has a status already
• Mold Breaker AI calc damage inaccuracy. E.g. Mold Breaker into Fluffy would see damage as if the mon wouldn’t be able to hit through.
• Figy Berry battler corruption when the pokemon was confused (the item was removed for wrong pokemon if the pokemon was confused by the berry)

Other

• Toggle running shoes action under utility for permanent running (credits: Jasper)
• Janine overworld sprite (credits: Frag)
• Signature color mugshots for E4 (credits: grintoul)
• Move type icons in battle
• Money max out under utilities
• Casual Mode
  
  • Egg generation by breeder in the setting house (generates valid, non duplicate eggs)
    
    • Valid eggs are all eggs with an egg group except Ditto (Manaphy and Phinone can be generated)
  • Unlimited Heart Scales
  • Pokemon signature items clerk + Silvally and Arceus items outside the house given by the kids
