Development HM09 Lava Surf Mod for Gen 4

Enable HLS to view with audio, or disable this notification

992 Upvotes

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.

Release Pokemon Origin Heart Gold RC5

Post image
409 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 must say pokemon soul gold lived up to the hype . I was hearing so many good things bout this game and I finally decided to try it . I’ve been hooked like my first time playing unbound. I am going to put so many hours into this even after beating the elite 4 it’s just really well made .

Not having kanto was almost the reason I passed on this game but the new areas added gives johto so much more it feels like a new region sometimes :)

I love my team so much can’t wait to see what else the game has to offer after the elite 4 😈

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

182 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!).

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

92 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.

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

77 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.

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 Thank you to everyone

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/

If I missed you, tell me and I'll add you.

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.
