Description
Pokémon Chaos Purple Version is a story-driven reimagining of the original Red and Blue journey. Join Red, Green, and their rival Blue as they set out from Pallet Town, only to uncover a dark plot involving Team Rocket and the mysterious “Project M.”
This ROM hack features an expanded storyline centered on Mewtwo, redesigned Kanto maps with a colorful Gen 4/5 aesthetic, and the return of the Sevii Islands. Built on the HG-Engine, ChaosPurple includes Pokémon up to Gen 9, regional forms, and Fairy typing—blending nostalgia with modern gameplay. Experience Kanto like never before.

- New Pokémon – Gen 1-9, including Regional Forms thanks to HG-Engine
- Fairy Type

- New Expanded Original Story with Original Characters
- Improved Trainer Battles – Gym Leaders have been rebalanced, to pose a new challenge!
- Post-game content and new Team Rocket story arc
- Return of the Sevii Islands!
IMPORTANT
I have had a number of people ask about later Gen Pokemon.. Let me explain. Yes they are available in the game itself as data – however in the current progress of the DEMO, they are not found in the wild YET – this is due to the game’s lore + story being FAITHFUL to canon, meaning Gen 1 in Kanto. HOWEVER, there are Gen 1 regional forms available to BATTLE with some trainers (meowth, rattata etc…) You CAN obtain a regional Pokemon in the demo as part of the story – but SPOILERS… In terms of later Gen availability – they will become available in the Wild when players reach Sevii Islands late game…

Do you know if there is higher Shiny Chance in this Rom-Hack? I just started playing and the second Rattata I encountered after receiving the Pokeballs was a shiny. Although I’d like to think I am extremely lucky, I know how impossible this is with normal shiny chances.
how can i get into silph co building?
Where can I find the Exp. Share?
Cant get through the port of Cerulean city to vermillion city?
The waiter says he is thirsty?
When I go into the pokemon in Viridian City and get Nurse Joy to heal my pokemon, just before she gives them back it freezes. I can’t pull up anything. I literally have to restart the game. Is there a work around or a way to get it to work?
the tea in celadon given by the old lady?
how long till you think this will be done
Finally you post this 👍
Why demo? Why
My only thought is why not spread the regionalscandcany non legendary in the wild like take alolan Vulpix for example if there’s a cave or a cold area it could be found there.
Finally you post this 👍
Hold up, this is base on Heart Gold but the experience is yet another Kanto playthrough. How’s that working?
