One of the most popularly played Pokemon ROM hacks till today is Pokemon GS Chronicles. Though the future update of the game is still questionable at the moment, it is still playable and fun.
It is an interesting ROM hack of FireRed, which takes the concept of Gold, Silver, and Crystal. The story is somewhat the same but at the same time different.
The game comes by default in a .BPS format which you can easily patch with any of the available patchers with no added cost.
The game has some bugs at the moment, but nothing too serious. GS Chronicles is still being developed with the help of the community.
The good thing is that you can always try it today, and the most exciting are the cheats that are available for this game. See our collection of working Pokemon GS Chronicles cheats.
Details on Pokemon GS Chronicles
Story
The story is inspired by the Generation II games, namely Gold, Silver, and Crystal. When we say inspired, it doesnโt mean that it follows the story point per point.
You could say that there are elements to it, such as taking place in Johto and having the usual point of being a Pokemon Master when itโs all over.

Features
The graphics of the game are updated, so it looks like HeartGold and SoulSilver. Pretty much everything is changed, so it doesnโt look anything like FireRed, so that alone is already a good improvement.
There are some graphical bugs in some cases, although it doesnโt really affect the gameplay.
The Pokemon roster is only up to Gen 4, which is around 494. The items, moves, and other things are all updated similarly to Gen 8. Another notable feature is the day-to-night cycle which was a mechanic back in the Gen 2 games.
Pokemon locations are also swapped and will appear depending on the time of day. The game has enough content for you to go around.

I have made it to olivine city, I have to use the wave ride to make it across to cianwood. Every time I walk up to the edge of the water it tells me โthe water is dyed a deep blue.โ Shouldnโt I be able to swim across normally without issues?
I tried playing but all my mons stopped obeying after level 10 even after i got the first badge there around (level 12 to 15 now) is this a bug?
Whenever I reach upstairs in the goldenrod tower it stops and sends a message on repeat and keeps going
on the second floor in the goldenrod radio tower, the guard is blocking the access to the third floor. im not sure what to do to get past them. help?
ps i have 7 confirmed badges, have talked to looker in front the tower, and did the double battle with the rival before the stairs to the 2nd floor.
Keeps crashing when I get to celadon
After applying any cheat, turn them off before proceeding. Or I would suggest restarting your game while all cheats are disabled, and then reopen the game.
Are the starters shiny locked?
Pls help, whenever I leave any Pokemon Center my screen turns to black and I canโt do anything. I literally canโt progress in the game now. Any help would be greatly appreciated :)
Hello MZ, thanks for coming here. Remove all unnecessary cheats from your emulator, leaving only the essential ones. If the problem persists, delete the .cheat file located in the root directory of your emulator. This issue arises when multiple cheats are enabled simultaneously, causing confusion in the gameโs programming. Hope my answer helps.
for some reason my game crashes a lot
Perhaps itโs an issue from patching. Make sure to follow the instructions provided in the game, this includes the recommended FireRed rom version for the game. Hope my answer helps.
Does anyone know when can you turn the fossils into pokemon?
pewter city
I cant use surfโฆ Can someone help me?
Eh I would like this game more if ultra gold sigma didnโt exist with more pokemon disappointing as this could have been easily better but even with every other game having up to gen 8 it only has to gen 4 basically just get the heart gold and soul silver rom for DS and you got the better version of this game.
How does the Unown Report work? I have caught them all and Bugsy and Cynthia are just chillin saying the same thing
Just an FYI, Iโm fairly certain this version is out of date. The current version is Beta v2.6 โ Build date 06/15/21. The version offered on here is Beta v2.6 โ Build date 12/07/20.
is it possible to catch all Pokemons here? like if i get chikorita as starter, can i get the other two starter from other sources? like trades or from random encounters?
Hi Alec, honestly I donโt have any information yet about this. Hopefully someone can give the input.
Sorry about the repeat comments. It wasnโt showing up on my end till now
Hello I recently started playing this and Iโm having issues changing the game to night time. I read something that said itโs through the pokegear map but I canโt find anything. Iโm playing through emudeck on the steamdeck if that helps
You need to find an option to enable the GBAโs Real-Time Clock. Iโm not sure how to do that on your platform, or if you even can. If you can, after you do so, you may also need to change your save type (again, I donโt know if this is something you can do on your emulation platform). You need to change it to Flash, and the size to 128k. You probably will want to ask a community for your emulation platform if these changes are possible to make.

Hello I recently started playing and I canโt figure out how to change it to night time. I read something that said there are settings on the map screen or something but I canโt figure out how to access it. Im playing through emudeck on the steamdeck if that helps.
One of the ladders in the lighthouse is missing ffs. FAIL
There is a door on the right you can see the shadow of the doorway/light of the door way.
funnily enough this happened to me on GBC As a kid. I got to this point then didnโt play for a week. Picked it back up and โwaitโฆhow do I get out?!โ Couldnโt find the hole so just restarted. Felt so dumb when I realized my mistake lol
All the added dialogue is quite annoying. Plus adding extra steps to progress, like get lucky enough to notice your rival in the PC to get past violet city, is pointless and stupid.
START ADDING WHAT VERSION OF FIRERED YOU USE FOR PATCHING!!!!!!
Hi there, thanks and thatโs indeed a good suggestion, I already added the FireRed version used for patching. See โGame Informationโ section.
While the version needed is stated, there are, bafflingly, two versions of the squirrels ROM out there with the exact same name. I have no idea what the difference is, though GS Chronicles requires the base game to be version 1.0, so maybe one of the squirrels ROMs is 1.0 while the other is newer. I donโt know. The version that shows up at the top of the Google results doesnโt work. I had to download a different version I canโt obviously link to it here, but the version needed is mentioned in one of the topmost search results; itโs how I got the right version.
so tried patching with everything under the sun game always freezes at Gameboy screen
Quick question: what is the location of Lugia I need it before I resort to cheats
Um, where can I find lapras in this game?
In the radio tower and the central park there is only 1 clerk at the desk, so I cannot do the quizz or start the bug contest.
Other than that I havenโt encountered any other issues.
Does anybody know the reason?
Hey how do I get the dexnav feature? I just started and am on eclipse gba emulator for iOS.
Is stantler a normal/psychic type? Because when i caught it, it says that itโs a normal type only but the docs says stantlerโs a normal/psychic type.
Hi there Blue, honestly I donโt have any idea about this yet. Hopefully someone from the community will give input on this.
Tried Fire Red v1.0 and it says โthis patch is not intended for this romโ in Flips
Mega Umbreon is a good idea for the Johto RomHack. Instead of just the canon Mega Evolution and Adddition of Johto starters.
Can anybody say which version of Fire Red is required to patch this rom because it says โthis patch is not intended for this romโ in Flips
Try using the V1.0 FireRed rom and not v1.1.
Hey uh I canโt play the hack my emulator says the file is corrupt and so I looked at the file and it has a ton of these question marks in boxes. Iโm not a coder but when there are more of those than anything else it looks crazy. I can send a screen shot if you want?
This is not a pre-patched file download. Above the download button, thereโs an instruction on how to patch the game. Hope this helps.
Hey, my game begin to jerk when i use fast forward on MyBoy. Is it a known issue oder how can i fix this?
Thx
Hello!
I just discovered your website and Iโm really glad I did! Super neat!
Fan games are just wonders!
I met some patching issues tho with GS Chronicles and Unbound. I tried to patch the FireRed base game version (Pokemon Fire Red Version (U) (V1.1) but both patcher inform me that itโs not the right game fileโฆ
It worked with the others I downloaded: Rocket Edition, AshGray, and Liquid Crystal.
Any advice would be appreciated!
Thanks in advance and thanks again for these games!
Hi FryTHF, I believe those rom hacks that fail to patch require v1.0. Many rom hacks need v1.0 and I believe it applies to Unbound and GS Chronicles.
I canโt get to Azelea
I canโt get to route 32
I beat Claire before I went back to Goldenrod for the story and now I canโt progress. I already have the sunset bell but i cant go farther than that. Itโs as if I didnโt actually beat it but i have the badge. Does anyone know how to fix this?

epic boy 999
this is a good game
does anyone know the shiny odds? cuz i got a shiny dratini from the elder in the dragons den and wanted to know the odds.
The game keeps freezing when anything evolves. Is there a way around this or an updated version coming that fixes it? Really want to play it.
Same. is there a solution for this? thanks for answering
Where do you find a sun stone?
I beat Clair before beating the Radio Tower and now the game will not allow me to advance any further
you have to do the tower before the gym so I think you have to reset to the last save file you had
some type of glitch keeps happening in my game cuz every time my pokemon evolves the game just freezes and thereโs nothing I can do about it and its very annoying because id rather not play through the game with stage 1 mons
DId you find out how to fix this issue becasue I finally got this game downloaded just to have the same problem, super frustrating to play to that point just to be stuck and not able to continue.
Same happend to me, is their a way to fix it
Did you find a solution? I have the same problem
Did you find a solution. i still canโt play
when my mudkip evolves the game freezes
Iโm stuck, I have all 8 Johto badges, but team rocket still has control of goldenrod. I didnโt mean to skip the Goldenrod rescue but it seems I did. I saw lurker enter the radio tower and the game let me clear the second floor of team rocket but it wont let me go any further. Iโm lost and donโt know what to do now.
What do I do with the silver and gold caps?
Is there a way I can play this on my android? I have a Samsung note Galaxy S20.
Yes, you can play this conveniently on your Android device. You need an emulator to do that, I recommend using MyBoy. Another thing you need to know is the patching process. Luckily we have created a guide for it on how you can Patch ips/ups files to play a ROM Hack.
Is this game shiny locked
the game is awesome! some things i experience while playing the game:
My skydive ride doesnโt work anytime i try to use it. I have a togekiss and honchkrow in my party and i have 7 badges, any idea on why this is happening?
Have you tried using the map to fly ? The actual skydive ride also says itโs not time to use it when you try to activate through select but if you use the map and choose a location, youโll fly there.
Are the trade evolution changed in this rom hack?
Sorry but I have no information for your question as of yet D4rkniSs.
Yes. Each one of those trade evolutions now requires a level up while holding a specific item. For Graveler itโs a Hard Stone, for Alakazam itโs a Twistedspoon etc. Thereโs a doc on the Discord for this hack that details these.

Hi Miguel, thanks for coming and sharing those cheats and I appreciate your hard work finding them. Will test them, just want you to know that weโre on the process of creating cheats for this game so stay tuned for updates.
Letโs make it simpleโฆ.

82003884 00F5 to big nugget
Cheat to $1

I donโt really get how this is used. I got it from any PC as stated on another site.
Then OAK just keeps saying itโs not the right time to do use it and nothing happens?
Are we suppose to use the big nugget on a pokemon to make its IVs Max? Or just sell for gold?
what generation are the Pokemon moveset based on? my Nuzleaf learned razer leaf when evolved at level 14 but it only learns razer leaf at level 14 in omega ruby and alpha sapphire
The game is absolutely beautiful! This is the first time i see such a polished and well-made Rom Hack. Are there any cheats yet? I kinda wanna mess around with the game a little.
Yes we do have cheats, see our Pokemon GS Chronicles cheats page.
I absolutely love this game AMAZING. I just started playing and Iโm already in love with this game. Amazing looking and well-made
Thanks for coming here Big D and leaving such a useful feedback.
