Pokemon GS Chronicles


One of the most recent ROM hacks or one that is still being updated today is Pokemon GS Chronicles. 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.

Details on Pokemon GS Chronicles


The story is inspired by the Generation II games, namely Gold, Silver, and Crystal. When we say inspired, it doesn’t 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 it’s all over.


The graphics of the game are updated, so it looks like HeartGold and SoulSilver. Pretty much everything is changed so it doesn’t look anything like FireRed so that alone is already a good improvement. There are some graphical bugs in some cases, although it doesn’t 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.

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?

Nick Rodriguez

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

Trent Soto

some type of glitch keeps happening in my game cuz every time my pokemon evolves the game just freezes and there’s nothing I can do about it and its very annoying because id rather not play through the game with stage 1 mons

Eric Kosick

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.

Kevin Abraham

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 can’t play
when my mudkip evolves the game freezes

Petite Hughie

I’m stuck, I have all 8 Johto badges, but team rocket still has control of goldenrod. I didn’t 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. I’m lost and don’t know what to do now.


What do I do with the silver and gold caps?

Adrian Seninde

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 doesn’t 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 it’s not time to use it when you try to activate through select but if you use the map and choose a location, you’ll 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 it’s a Hard Stone, for Alakazam it’s a Twistedspoon etc. There’s a doc on the Discord for this hack that details these.


Spreadsheat with all changed evos and pokemon included
yes they are changed and the details are in here


Thanks for coming here Marley and sharing that valuable link, I appreciate your help. Keep em’ coming..


I have a bit problem on the patch, i patched the game but it crashed my emulator, do you have a link of a pre patched version?? please i really want to play the game


Sorry Zakku but we don’t share pre-patched version here. Also, be sure to follow our rom hack patching guide.

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 we’re on the process of creating cheats for this game so stay tuned for updates.


Let’s make it simple….
Go to market
Then 82003884 0268 to silver bottle cap
82003884 00F5 to big nugget

Cheat to $1
3C25A344 FD8F451C
AD86124F 2823D8DA


I don’t really get how this is used. I got it from any PC as stated on another site.
Then OAK just keeps saying it’s 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.
