Pokemon GS Chronicles is a GBA ROM hack based on Pokemon FireRed, created by Ruki Studio. It’s a Johto-inspired adventure with a brand-new storyline, Mega Evolution, a full day and night system, time-based wild Pokemon encounters, and tons of quality-of-life improvements that the original Gold and Silver never had. The latest version is v2.7.6, released on June 19, 2024.
What Is Pokemon GS Chronicles?
Pokemon GS Chronicles is a GBA ROM hack of Pokemon FireRed built to be a spiritual reboot of the Generation II games — Gold, Silver, and Crystal. It’s not a straight remake. The creator took the Johto setting and threw in an entirely new story, new characters, and modern mechanics that make it feel far more polished than the originals.
You play in the Johto region with maps based on HeartGold and SoulSilver. Professor Elm sends you and your rival on a mission after a mysterious red-haired trainer steals a Pokemon from his lab. Sound familiar? It is — but the way it plays out is different from what you remember.
The game is built on the FireRed engine, which means it plays as a standard GBA ROM. You can run it on any GBA emulator for Android or PC, no special setup needed.
Why Pokemon GS Chronicles Still Gets Attention
Johto is one of the most loved regions in the entire Pokemon series. Gold and Silver have a huge nostalgic pull, but going back and playing the originals in 2024 can feel rough. GS Chronicles fixes that.
The graphics are lifted from HeartGold and SoulSilver. The HM system is gone, replaced by PokeRides. Wild Pokemon change depending on the time of day. The type chart includes Fairy type. The original HGSS soundtrack is in the game with proper quality. These are the things the original GSC needed but never got.
It also keeps getting updated. Most GBA ROM hacks go quiet after a year. GS Chronicles has been active for years and is still receiving bug fixes and content improvements. That’s rare, and it’s a big reason the community keeps coming back.

Pokemon GS Chronicles Latest Version
✅ Latest Version: v2.7.6 — Released June 19, 2024
In v2.7.6 you can earn all 8 Johto badges and challenge the Pokemon League. Post-game includes Gym Leader rematches and Elite Four title defense battles. Kanto is still in development.
The current version is Beta 2.7.6, which came out on June 19, 2024. This build added Elite Four rematches and title defense battles, a Shiny Charm item, improved Goldenrod City graphics, better multiplayer battle compatibility, and the usual round of bug fixes.
Some sites label this version as “completed” since you can finish the main story, beat the Pokemon League, and access full post-game content. Technically though, it’s still listed as a beta because Kanto is confirmed to be coming in a future update. The creator has confirmed Kanto will be in the game — the trainer card was already modified to support 16 badges — but Kanto isn’t in the current build.
The game has been in development since around 2014. Updates have been fairly consistent over the years, and the creator has stayed active with the project.

How to Play Pokemon GS Chronicles on Android
📱 Android Setup: My Boy and Pizza Boy GBA both run Pokemon GS Chronicles well. The creator specifically recommends against VBA — it causes crashes and Pokedex issues. mGBA also works well and supports the built-in multiplayer battle feature.
Playing on Android is straightforward once you have the patched ROM file:
- Download the patched .gba ROM to your phone
- Install My Boy or Pizza Boy GBA from the Google Play Store
- Open the emulator and tap the file browser to find your ROM
- Tap the ROM file to load the game
- Go into emulator settings and make sure Save Type is set to Flash 128k
- Save using in-game save (not just emulator quicksave) to avoid losing progress
The day and night system runs on real-time, so set the correct time in your emulator settings if you want time-based events to work properly.
How to Play Pokemon GS Chronicles on PC
- Download mGBA (recommended) or VisualBoyAdvance-M for Windows, Mac, or Linux
- Open mGBA and go to File → Open
- Browse to your patched GS Chronicles .gba file and open it
- Go to Tools → Game Boy Advance → Override save type → Flash 128k
- Configure controls under Tools → Key Bindings
- Use in-game save at a Pokemon Center — don’t rely only on save states for long-term progress
Avoid the old VBA (Visual Boy Advance) emulator for this game. The creator specifically called it out — it causes Pokedex crashes and issues with certain items. VBA-M is a bit better but mGBA is the safest choice.
Is Pokemon GS Chronicles Completed?
This depends on how you define “completed.” The main story of Pokemon GS Chronicles is fully playable. You can:
- Earn all 8 Johto badges
- Challenge and beat the Pokemon League
- Rematch all Johto Gym Leaders
- Do Elite Four rematches and title defense battles
What’s still coming is Kanto. The developer has confirmed it and even modified the trainer card to hold 16 badges. But in the current v2.7.6, Kanto isn’t in the game yet.
Status: Beta — Main Story Complete, Kanto in Development
GS Chronicles is an ongoing project. The Johto portion is fully beatable with post-game content. A full Kanto expansion is planned for a future release.
Pokemon GS Chronicles Cheats
Cheats do work in GS Chronicles since it’s based on FireRed. Most GameShark and CodeBreaker codes that work in FireRed carry over, though results can vary by emulator.
Popular working cheats include: unlimited Rare Candy, Master Ball cheat, unlimited money, walk through walls, and shiny Pokemon encounter. The wild Pokemon modifier also works by gen (Gen 1 through Gen 8 codes are available).
A few things to keep in mind:
- Enter cheats as GameShark / Action Replay type in your emulator
- Don’t run too many at the same time — it can cause crashes
- Always save your game before activating a new cheat
- Walk through walls works but can get you stuck — save first
- Shiny encounter cheat works on My Boy but may cause a name glitch when you catch the Pokemon
- VBA has lower compatibility with cheats — use My Boy or mGBA instead
The teleport/warp cheats from FireRed don’t work because the locations are different in this hack. Stick to item and encounter cheats for the most reliable results.
Things to Know Before Playing
- Use FireRed v1.0 (not v1.1) — the patch requires the v1.0 ROM specifically
- Set save type to Flash 128k — required in your emulator settings to avoid save data corruption
- Avoid VBA — causes Pokedex crashes and item glitches; use mGBA or My Boy instead
- PokeRide visuals are buggy — when using a PokeRide, the Pokemon picture and cry will show a question mark. This is a known visual bug that doesn’t affect your party Pokemon
- Haunter evolves without trading — hold a Spell Tag and level up at night
- Trade evolution items — go to Lake Rage on Route 43. There’s a man in a house who swaps trade items for Heart Scales
- Riolu location — near the Union Cave entrance, low encounter rate so it takes patience
- Multiplayer battles — go to the second floor of any Pokemon Center. Works with mGBA, MultiGBA S, and My Boy
- Surf replacement — after beating Cianwood City gym, the woman outside gives you Skydive Ride (this game’s version of Fly)
Pokemon GS Chronicles vs Other Johto ROM Hacks
If you’re into Johto-based ROM hacks, here’s how GS Chronicles compares to others worth playing:
Pokemon Liquid Crystal is the classic Johto remake — it follows Crystal’s story closely and adds the Orange Islands. GS Chronicles is more of a reboot with a different script, better graphics, and more modern mechanics.
Pokemon Scorched Silver is a newer Emerald-based Johto hack set 20 years after the original games with a completely new story and team. More recent feel, different tone than GS Chronicles.
Pokemon Quetzal is best for multiplayer — up to 4 players in Hoenn. It’s not Johto, but if you want modern features and co-op play, it’s one of the best GBA hacks around.
Pokemon Unbound is the most complete and polished FireRed hack out there. Not Johto-themed, but if you want a challenge with tons of content, it’s hard to beat.

Final Thoughts
Pokemon GS Chronicles is one of the most ambitious Johto ROM hacks out there. It’s not trying to be a 1:1 Crystal remake — it’s its own thing built on the bones of a beloved era. The HGSS graphics, proper soundtrack, PokeRide system, and Mega Evolution all make it feel more modern than the originals without losing that Johto feel.
The fact that it’s still being updated and Kanto is planned makes it worth starting now. You’ll get a full Johto run, solid post-game, and a Kanto expansion waiting in the pipeline.
It’s best for players who already know and love Johto and want a better version of it — not a nostalgia trip, but a genuine upgrade. If that sounds like you, GS Chronicles is worth the download.
