About This ROM Hack
Pokémon Emerald Party Randomizer Plus (PEPR+) is an advanced evolution of Googleben’s original Party Randomizer, originally created for streamer SmallAnt. Unlike traditional randomizers, this hack randomizes your entire party at the start of every battle, while still preserving progression, balance, and strategic depth.
PEPR+ enhances the concept by introducing level-based evolution logic, smarter move selection, controlled legendary odds, TM/HM influence, and egg move integration, ensuring the game remains fair, engaging, and skill-based rather than pure chaos.
This hack is ideal for players seeking a highly replayable, unpredictable challenge without sacrificing long-term progression.
Story Overview
Pokémon Emerald Party Randomizer Plus retains the original Pokémon Emerald story set in the Hoenn region.
There are no narrative changes. The core gameplay twist lies entirely in the battle system: every battle reshuffles your party into different Pokémon, forcing constant adaptation while still rewarding smart team-building decisions through item management and progression.
Key Features
- Party Randomization Per Battle: Every Pokémon in your party transforms into a random species at the start of each battle
- Progression-Preserved Stats: EVs, IVs, HP %, EXP %, shiny status, Pokérus, contest stats, and nicknames persist across randomizations
- Level-Based Evolution Logic: Pokémon evolve within level ranges—low levels stay unevolved, high levels guarantee final evolutions
- Controlled Legendary Odds: Legendary Pokémon are extremely rare early-game and become equally likely after level 40
- Expanded Level-Up Movepools: Pokémon select moves from a wider pool, including previous evolutions for stone-based evolutions
- Egg Move Integration: Pokémon can receive Egg Moves, with chances increasing by level and capping at level 20
- TM/HM Influence System: Owned TMs and HMs influence possible movesets, allowing indirect player control
- HM Storage System: HMs can be deposited into the PC to remove them from the random move pool
- Smart Move Replacement Logic: Weak, duplicate-type, or low-impact moves are replaced first
- Smeargle Special Handling: Smeargle receives fully randomized movesets based on expected Sketch usage
- Ability Randomization: Pokémon abilities are randomized each time they transform
- Surf Safety System: Using an HM re-randomizes the party to prevent being stranded
Known Bugs & Issues
- There is a small chance that a non-shiny Pokémon appears shiny for a single battle

Story
This Hack randomizes all of the Pokemon of your party at the beginning of every battle. The player gets a real sense of progression and can influence a bit what moves a Pokemon can receive.
List of Features
- Every Pokemon is randomized into a random species at the beginning of each battle, with each species having equal weight.
- Pokemons preserve their EV points, IV points, contest conditions, current HP percentage, XP percentage, shiny, pokerus, and nickname across randomizations.
- Each Pokemon receive their last 4 level-up moves for their moveset.
- Pokemon evolve within specific level ranges, at random. A level 5 Pokemon will always be in its first stage of evolution, while a level 60 Pokemon will always be fully evolved.
- Legendary Pokemons are rarer to get when low level. They gain the same chances to appear as any Pokemon family after level 40.
- Pokemon choose from a slightly wider level-up movepool and choose from the previous evolution in the case of a Stone evolution Pokemon.
- Every Pokemon has a chance to obtain an Egg move. The higher level you are, the higher the chances, capping at level 20.
- Every Pokemon can learn moves from the TM/HM you currently have in your bag. Each TM/HM you have increases the chances for each Pokemon to learn a TM/HM move by 10%, making it 100% certain to learn something if you have at least 10 TM/HM. If the Pokemon learns a TM/HM, it will choose one of the compatible moves from what you have. Managing the TMs you carry around may thus allow you to control to some degree what your Pokemon can learn, but you can't just leave one TM so that all your Pokemon learns it all the time!
- HMs can be deposited into the PC. As such, you don't need to avoid getting the weaker HMs to remove them from the possible TM pool.
- For both Egg moves and TM/HM moves, if the Pokemon already has a full moveset, it will give a score to each move according to how essential it is offensively, and replace only moves that are given the lower score, or a move of the same typing if considered better. This means that duplicate typing moves and status moves are prioritized.
- Smeargle gets an entirely randomized moveset, according to the number of times it should have learned Sketch by its level.
- Booting up an HM randomizes the Team again so that you don't end up stuck on islands with no Pokemon able to Surf.
- Abilities are randomized.
