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.

  • RZE tile system.
  • Day and Night system and day/time-based events.
  • Wild Pokémon switching depending on the time.
  • Original soundtrack ripped from HGSS (Initially used GogojjTech’s low-quality music, but I decided to rip them by myself with a way better quality).

  • New Regional Pokedex including 494 Pokémon from first 4 gens + Sylveon.

  • Daily Wondertrade with in-game trainers.
  • Move tutors on every PC.
  • And even more…


Beta 2.7.4May 18, 2024

Bugs fixed:

  • [FIXED] TM Case no longer crashes in real hardware and iOS emulators (The culprit was a simple graphic that had the wrong size and caused a memory overflow lol).
  • [FIXED] Wild encounters in some areas are corrected. (Credits to BarleyOats
  • [FIXED] Removed the high-quality sound mixer and reverted to the vanilla mixer as a possible remedy to fix random crashes.
  • [FIXED] Rocket grunt at the Rocket Hideout that had no team assigned and caused the game to crash after battling him has been fixed.

New oddities:

  • Some trainers from the Super Nerd and Lass may cause a visual glitch in their names. Still finding the cause of that visual glitch. Not harmful. and will not cause any issues. (Still have no idea what causes that visual error)

Beta 2.7.3May 12, 2024

Bugs fixed:

  • [FIXED] Trainers in a few routes using overleved Pokémon that could cause an instant K.O.
  • [FIXED] Poké Rides now show the picture and cry of the first Pokémon of your team, this was made intentionally as a workaround to prevent crashes when using them. Still working on a proper solution.
  • [FIXED] Bright Ride no longer freezes the game when you don’t have the Zephyr Badge.
  • [FIXED] Light Clay is finally programmed, so now Pokémon that normally hold it will have it.
  • [FIXED] Paldean Tauros should give the correct exp. amount.

New oddities:

  • Still finding what causes random crashes only on iOS emulators.
  • Some trainers from the Super Nerd and Lass may cause a visual glitch in their names. Still finding the cause of that visual glitch. Not harmful. and will not cause any issue
