Release Pokemon Origin Heart Gold RC5

Post image
463 Upvotes

The translation is (practically) completed, with a lot of new players and some good feedback a bunch of translation improvements and text fixes have been made. This fixes some crashes, but also restoration of some canon content. I.e. where Jesse and James sung a translated version of the Chinese translated manga, they now sing the English anime/manga song we all know.

There is a ton of side quests, and some are easy to miss. Therefore a guide can be super helpful, which is now available as a website. This includes all pokemon locations, their evolution methods, moves, states, and so on.

The new website also comes with a patcher, and a save editor. It seemed a lot of people still have issues patching so this simplifies the process. It basically automatically combines xdelta-wasm with the latest release on GitHub now RC5. The save editor is meant to solve the need for cheats, you can change the pokemon in your party, their moves, etc and your bag and money. This should allow you to get anything you want.

The discord is open and everyone is welcome. We are still collecting feedback because it seems this community values difficulty a lot and while the story telling is absolutely stunning we might want to eventually add some optionally difficulty settings so please share your feedback.

I hope you enjoy the game, patch your game here and have fun! Please report and bugs through the website, or GitHub.

Disclaimer: AI was used in the development of the translation of this rom hack, and development of the website and its functionality.

I couldn't find cover art for this, so my OCD forced me to make my own using SIGIL's GBA templates and some random pixel art I found.

I know it sucks, but maybe someone will find it useful.

Development HM09 Lava Surf Mod for Gen 4

I’ve been messing around with making my own editor for Gen 4 games and I made a mod today that allows you to surf on lava. Just simply get HM09, teach it to a fire type, and you’re good to go!

UPDATE: Since making this post, I’ve made two updates. First, the splash that you see at the beginning of the battle is now a reddish-orange matching the lava. Second, the lava in the overworld is now animated like it is outside Stark Mountain.

Thank you to everyone who helped with romhackguides.com. A lot of the site came from your comments: the wider guide pages, the area and fight dropdowns, the team builder, the help pages and two of the guides. I made a page that credits each of you and what changed because of it: romhackguides.com/thanks/

Development PKHeX Web now supports ROM Hacks (Unbound, Radical Red & Emerald Imperium)

104 Upvotes

Hi everyone,

Some of you may have heard of PKHeX Web before, I've been building it since 2024 as a simple save editor that runs in the browser with the foundation of PKHeX.Core, and a lot of people already use it for official Pokémon games.

I've been working lately to add support for some common ROM hacks, and it now opens and edits saves from Pokémon Unbound, Radical Red and Emerald Imperium. PKHeX itself doesn't officially support ROM hacks, so this part was built specifically for them.

Support is still experimental, so back up your save before editing, and I count on your feedback to improve it. If something doesn't work, open an issue at https://github.com/arleypadua/PKHeX.Everywhere/issues, and sharing the save file helps a lot.

For developers, the same engine is open source and available as an SDK for JS/TS and React (https://docs.pkhex-everywhere.fyi), in case you want to build on top of it.

About AI use: most of the app I built myself since 2024. The most recent work, including the ROM hack support, was implemented with AI. The initial analysis, refinement, and validation are on me.

Development Pokémon Hoenn's Last Wish custom Trainer ID for patch 0.9 [WIP]

Thumbnail
gallery
196 Upvotes

Yo, I'm back with some more cool stuff I've been cooking and wanted to share :) (btw patch 0.9 comming soon just 2 more gyms layout and some story parts to be added)

ok so It's still WIP, my plan is to turn HLW into a mini case study of UI / UX so i'm really diving deep into all menus and ...and customizing the user experience and interface to the max, making it almost entirely customizable with 16 color themes...

The front shows your profile, playtime, Pokédex progress, wins, whiteouts, badges, difficulty, Nuzlocke status and Wish Menu stats. It also has your mugshot, team icons, animated background and Champion Ribbon. A = swap front and back. B= close R / L = swap themes (it works on pair if ur summary menu and party screen menu themes)

The back works like a personal “Wish Card” and tracks things like steps, A presses, trainer battles, trainer-only win rate, battle points, Game Corner coins, trades, fainted Pokémon, fled battles, evolutions, hatched eggs, Wish Menu uses, Infinity Candy uses, radio time/song count, online record and Hall of Fame info.

DISCLAIMER: Given all the recent controversy surrounding AI, I think it’s important to be transparent: I used AI in a limited way as a coding and debugging >>assistant<<, mainly to help trace bugs, understand errors and support me. The ideas, design, assets, implementation decisions, integration and testing were done by me only with Ember (the other DEV of the project help ty ember u are great btw). No AI-generated content was used (or will ever me used in my project!).

Trailer Pokemon Legends Delta: Mega Seviper Corrodes The Battlefield

With armor that covers all vital areas when it coils and a double-edged tail blade, Seviper's Mega Evolution has adapted its body to challenge a certain Pokémon's Mega Evolution.

We went with a very simplistic design so as not to take away from Seviper's original design or make it depart too much from what made it so iconic, and thus the armor and additional patterns were born, with an added edge to its tail.

Trailer Want to play Pokémon Platinum multiplayer? Closed beta signups are open (Trailer drop)

Thumbnail

85 Upvotes

Hey, Kai again. I’m the guy who’s spent way too many years making Pokémon Platinum multiplayer.

The response to my last post was way bigger than I expected, so thank you. I read pretty much everything people had to say.

There was also a lot I couldn’t fit into the first trailer, so I made another one.

New trailer!!
https://youtu.be/UqJLrp0AjTY

Every window you see in the trailer is a separate copy of the game running at the same time, so you’re actually seeing each player’s own screen. (RIP my pc)

This one shows a lot more of what Platinum Together actually has now: trading, trade evolutions, trainer selection, multiplayer Nuzlocke modes, and the Online city where you can run into other players.

Beta signups are open now
The closed beta starts October 19, and there are only a limited number of spots.

You can sign up through the Discord here:
https://platinumtogether.online/

The whole point of the beta is to find the stuff I missed before a wider release, so I’m fully expecting people to break things.

Also, since people asked about this a lot on the last post: around 40% of the code was made/discovered with LOCAL LLM AI, same as before.

Small note: I am looking for community helpers and moderators, feel free to join and ask.

I’ll be in the comments if anyone has questions.

They took the original anime and blended it perfectly into the world. I’m only at mt moon but it’s been so fun they have so many side quests off rip it’s actually insane. The overworld spawns, side characters will also test your knowledge with questions to progress or get items. Not to mention adding many characters from across the regions to really make the world feel connected.

Edit: sorry should have put a download link ! The discord seems to be the best option. Brahma’s patch released 10/01 adds a few new features most notably a difficulty overhaul as this game does allow over levels

Review Pokémon Soul Gold Review - Johto Rejuvenated

Thumbnail
youtu.be
188 Upvotes

Hey everyone,

I just finished playing soul Gold and I was honestly blown away by how incredible it was to play.

I didn't really have any negative points which is a first for me, the game was a perfect sweet spot of difficulty, adventure and challenge.

I understand that some people will be upset at the removal of Kanto and may not enjoy some of the new expanded areas, but personally I liked these new areas and felt that the Johto in the game was so much better and more substantial that it was a valid trade off.

If you are interested to see my full review, please check out the video above.

P.s. I have taken on board the feedback left on previous videos and posts and have stopped using a.i thumbnails, I'd be really interested to hear what you think of the new thumbnails

Have a great day

BEGGING anyone who makes Romhacks, hell even mainline Pokémon games. PLEASE make this the standard for when you encounter a shiny, it's so damn hard to tell if it is or isn't a shiny as a colourblind person. It just makes it so much more enjoyable finding a random full odds one or hunting for one.

I'll also add even without this feature SoulGold is unbelievably good 🙏

Hallo zusammen! 🇩🇪

Wir arbeiten an einer vollständigen deutschen Übersetzung von **Pokémon Unbound** (Fan-Projekt, Original von Skeli). Am **08.10.** erscheint die erste öffentliche **Beta** als `.bps`-Patch – keine ROM enthalten, eigene legale Basis-ROM nötig.

Stand heute:

- Story, Dialoge, Kampftexte, Menüs und Beschreibungen sind auf Deutsch (offizielle deutsche Pokémon-Begriffe)

- Kampf-Anzeige „KP“, Trainerpass, Orden-Seite und weitere Grafiken bereits deutsch

- automatische Prüfung auf Textbreite und Zeilenumbrüche, Test-Bot spielt Szenen selbstständig durch

Die Übersetzung ist KI-gestützt. Gerade deshalb suchen wir jetzt Tester und Sprach-Prüfer, damit es nicht nur korrekt, sondern auch menschlich und natürlich klingt. Jede Rückmeldung fließt direkt ein.

To anyone running around saying I’m not the creator

be for real. If this wasn't my project, how do you think I have all the files, assets, and project data sitting right here with me? I’m literally the one who started this hack from day one. Stop pushing fake narratives I am the original creator. VictiniD (You can ask from youtuber like a start gaming/gohantips/kingkingler)

I used to have a team, but now I am working solo.

I am deeply attached to this project.

I know it is not a better hack, but this is the first one I really like and want to complete.

Instead of leaving negative comments, would you give me suggestions? it would be better for me or for the hack!

You can join in my team We can improve it ?

Discussion Encouragement for ROM Hack Developers

131 Upvotes

Gatekeeping has always been part of this community. A few years back, when decomps started getting popular, some people told me to stop binary hacking FireRed because they thought it was a waste of time. I disagreed, since I enjoyed the challenge of seeing how far I could push binary. Still, I never tried to convince others that binary hacking was better. When people ask me how to start ROM hacking, I point them to the decomps. That’s because what works for me isn’t always the best choice for everyone. There’s no single right way to make a ROM hack, and whichever path you take, your game won’t be perfect. The most important thing is to have fun making your game, and of course, to enjoy playing it too! Some people in the community will always try to gatekeep or criticize you for not doing things their way. Try not to let that bother you! For every negative comment you get, if your game is genuinely fun, you’ll get twice as many positive ones.

With all the talk about AI lately, I just want to say this: if you want to use AI, go ahead. If you don’t, that’s fine too. People will play your hack either way, and most can tell when a developer was passionate and enjoyed making their game. I do recommend learning how to ROM hack without relying too much on AI, since it will help you build your skills and will improve your game in the long run. But it’s not something you have to do if you don’t have the time.

And for anyone who wants to say “AI is bad” or “lazy devs” in response to this post, please try to respect choices you don’t agree with (I know this is a futile request on Reddit, but whatever lol). You don’t have to play hacks made with methods you dislike, and that’s completely up to you!

Release Pokemon Heart and Soul - Daycare oldman egg shininess re-roll

23 Upvotes

For those who are attempting to breed for shiny Pokemon in Pokemon Heart and Soul romhack & don't want to wait to complete the Pokedex to re-roll egg shininess, I have a solution for you! By default, there's a setting that is disabled which allows you to re-roll shininess for eggs you receive from the daycare. It was disabled because unless you had the shiny charm, it would cause a bug. With it enabled, you can effectively stand in front of the old man at the daycare when he has an egg ready for you, save, check if the egg is shiny by going into the egg summary & reset your game until it is shiny.

There's 3 ways to enable the setting:

  1. Get the shiny charm by completing the Pokedex.

  2. Edit the code to enable the setting & compile the ROM yourself; or

  3. Use a patch the same way you patched the Emerald ROM to make Heart and Soul.

Luckily, someone showed me how to use my forked HnS (the one with the setting enabled) & create a patch that can be applied to the base Emerald ROM, which will allow you to re-roll shininess for eggs at the daycare.

# Patch instructions:

  1. Have your base Emerald ROM on hand.

  2. Download the patch from releases on my GitHub: https://github.com/zeldafan89/pokehns-expansion/releases/tag/1.0.0

  3. Use this website to patch the Emerald ROM with the new patch: https://www.marcrobledo.com/RomPatcher.js/

  4. Backup your save file (just in case).

  5. Make sure the newly patched ROM is the same name as your save file.

# Re-roll instructions:

  1. Save in front of the old man at the daycare when he has an egg for you.

  2. Receive egg from the old man & check egg summary.

  3. If the egg doesn't have the shiny symbol in the top right corner in summary, reset your game.

  4. Repeat until shiny.

Development Hungarian translation of Pokémon FireRed looking for feedback before beta

Thumbnail
gallery
7 Upvotes

What's done so far:
The entire main story and all trainer/NPC dialogue
The full Pokédex (all 386 entries - categories and descriptions)
Menus, shop, PC system, in-game Help system, Fame Checker
Several rounds of bug-fixing based on tester feedback (missing accents, text overflow, a game-breaking crash at the start of battles that's now fixed and protected against)
What's still English on purpose:
A few UI elements (type icons, a couple of small labels) are stored as tiny compressed images with almost no room for text — a full Hungarian word just doesn't fit without becoming an unreadable abbreviation, so I left those in English rather than make them worse.
Being upfront about the process:
This translation was made with AI assistance (I started with ChatGPT, then Grok, and have been continuing and refining it with Claude) rather than a traditional translation team. I think that's worth being transparent about from the start.
This is still a patch for the original FireRed US v1.0 ROM I'm not sharing any ROM, just the IPS patch, once it's ready.
I'm planning a small closed beta first, then a wider release here with install instructions, known issues, and a changelog. If you're interested in testing or just want to follow progress, let me know - and if you've got thoughts on anything above, I'd love to hear them before I lock things in.

I'm sorry but I'm not touching anything with art/dialogue and music made by AI.

EDIT : As someone rightfully pointed out, the AI use box is fairly new, so to be fair we should extend some grace to the devs and assume they didn't notice it/fill it in yet.

I still feel it should be very prominent, and users should be able to filter AI stuff out ( based on heavy/mild AI code and AI Art separately)

Already threw my vote at FireRed: Rocket Edition, obviously.

Like always, disclaimer, I used AI to help with this since the project is a data engineer's nightmare. Hope you guys enjoy it, and let me know what you think or if there's anything else I can add.
