  • Creator: ~Ruki!
  • Version: Beta 2.7.1
  • Hack of: FireRed
  • Updated: May 25, 2023

Pokemon GS Chronicles is a GBA Rom Hack based on Pokemon FireRed. It has a New Story, Mega Evolution, Day and Night System, Time-based Wild Pokemon & Much More!

Also, be sure to try out Pokemon Fire Red Extended

I have no idea how to describe the main plot and storyline since many events are essentially the same form HGSS/GSC, so we can at least assume the plot may remain the same (Tbh is not the same, but at least you may get a surprise by playing the game.


Please go through the known bugs section on Pokecommunity.


The famous Professor Elm has been busy with several new findings, among them the legend of the miraculous stones that did reach the Pokémon a higher level, due to this resorts to two of his assistants, Ethan/Kris and [Player], to deal with the operation of these, giving them a Pokémon for this. After sending [Player] to pick up a package with Mr. Pokemon, a mysterious red-haired guy steals a Pokemon in your laboratory. Now Ethan/Kris [Player], which received a Pokedex from Prof. Oak, will undertake a travel around the Johto region to complete the Pokedex and know who was that redhead boy and why he stole the Pokemon.

I have no more ideas and inspiration to continue that hackrom. It’s not cancelled at all, but I have no plans to continue with it right now.

Heck no! This hack is a reboot, the same objetive but different storyline and scripts. The story is a mashup of the concepts of Pokemon Gold, Crystal, Heart Gold and personal concepts.

Yes, I can only confirm another rival now, your gender counterpart is another rival.

It’s based on this old artwork (I have no idea at this time who the artist is. The artwork was taken from a fake leak from HGSS around 2009) http://i.imgur.com/3VC01Ep.jpg

Kanto is confirmed. A Johto story without Kanto is incomplete, lol, and nope, I have no plans to put more regions, only Johto and Kanto
