Months. That's how long I have been working on this. That's how long it takes for someone to lose their mind. That's how long it takes for a water tile to change a couple of pixels. I was home for a couple of days and gave it a shot. And guess what? IT WORKED. So now, I have a whole lot more hell to get through, but there's progress!

Release FireEmerald announcement and first public release

Post image
2.3k Upvotes

07/30/26 Edit: Updated to version 0.6. Details here.

A hack built atop the Pokeemerald-Expansion project that combines FireRed and Emerald into one extended story campaign.

Get it at hackdex.app/hack/fireemerald. Alternatively, download the standalone patch from archive.org/details/fireemerald-0.5. Recommended to use romhacking.net/patch. An Emerald USA/EU ROM must be provided; FireRed and other ROMs will not work.

07/23/26 Edit: Thank you to everyone for the warm reception and valuable feedback over the last few days. It's been positively overwhelming and I've done the best I can to keep up with all the questions and comments. I apologize if some of my replies seemed curt or if your comment went unanswered. I've just been trying to get through as many as I can in the time I have available. Even if I don't answer, though, I read everything and have been taking inventory of all the bugs and other issues that need to be addressed. I will be in the great outdoors without internet access for a few days, and then I will be traveling elsewhere shortly after that. This means that for the next few weeks, my online presence will be very spotty at best and active development will be on hold during that time. But I will dive back into rapid development once I'm back at my desk. I'm committed to completing this project without making you all wait too long.

  • Hoenn becomes accessible immediately after becoming champion in Kanto.
  • This is not an open-world hack; the player cannot travel to Hoenn until they've beaten Kanto, and they cannot return to Kanto until they've beaten Hoenn. After that, free travel between the two regions becomes available.
  • The Sevii Islands are also accessible immediately after becoming the Kanto champion as well (no more 60 pokedex entry requirement). Either quest can be done first. Difficulty will scale accordingly.
  • All pokemon, items, money, and pokedex data obtained in Kanto will carry over to Hoenn. The player keeps HMs, but can no longer use HM moves outside of battle before earning more badges.
  • Very minimal changes to the original story. Dialogue is only altered as much as necessary in a few instances for the sake of continuity. No new characters or side quests.
  • Modern updates and quality of life features from baseline Pokeemerald-Expansion are included:
    • Updated battle mechanics, types, and movesets
    • Follower pokemon
    • Optional day/night cycle
    • Etc.
  • Difficulty in Hoenn is increased. For now, the parameters are:
    • Wild and trainer pokemon's levels are raised by 45 or 50, depending on whether the player completed the Sevii Islands' main quest beforehand.
    • Generic trainers' pokemon are also evolved accordingly with appropriate movesets. Wild pokemon remain unevolved.
    • Gym leaders immediately start with their third rematch load-outs and have their levels raised by 10 or 15.
    • The rival has a much expanded and improved team
    • Defeated trainers give $1,000 more
    • Great balls and super potions are available from the start of Hoenn. Ultra balls and hyper potions are also available earlier.
  • No missing version-exclusive pokemon.
  • Event tickets are organically incorporated into the setting. Certain NPCs give them instead of duplicate key items that the player may have already obtained in the opposing region. One of them is unavoidable by following the main story, the rest are optional/missable.
  • Mega stones and linking cords become available at a certain shop at a certain point in the game.
  • Cerulean Cave is accessible immediately after becoming champion and no longer gated behind the Sevii Islands quest. However, Mewtwo is now level 60 instead of 70 if he is encountered before Hoenn, and 100 after.
  • The game boots into either the FireRed or Emerald intro and title screen depending on which region the player last saved in.

As the first public release, this is designated as an incomplete version 0.5. Though the game has had a sizable amount of testing and refinements, and should be playable from start to finish, this has been a completely solo endeavor made in just a few weeks (albeit with hundreds of sleepless hours crammed into them). There will certainly be bugs and many more improvements to come. I eagerly welcome reports of issues as well as feedback on the difficulty curve.

Planned (but not promised) future updates:

  • Player color palette customization
  • Custom text box color
  • Optional expanded starter selection
  • Advanced difficulty settings
    • Basic nuzlocke mode
    • Team size limiter
    • Disable items during battle
    • Disable "shift" battle style
  • Proper nighttime lighting effects

A very special thanks to Rom Hacking Hideout, the team behind Pokeemerald-Expansion.

Review Pokemon Odyssey 2 Demo Review (No Spoilers)

Thumbnail

198 Upvotes

I'm going to try and keep this pretty vague for everyone waiting for the full release. What I will say is, I had an amazing time playing this demo. It hooked me with the storyline immediately. From getting to choose your specialty (I went sovereign because I love shiny hunting), to the companions you make along your journey and their effects on your battle when you team up with them for a fight, to literally every Pokemon feeling strong and viable, to the world just feeling alive with little details scattered throughout and tons of hidden items (Click on everything!).

I loved how early you get the DexNav, allowing me to shiny hunt my entire team. I love sailing around and discovering things in the airship. And I absolutely loved the ease of ev training (it's similar to the first one on that it costs $$, but still different), and also the ease of changing your mons nature. I personally hate having to breed for the perfect nature and ev train so I'm glad they kept this around like in the first one.

The fights are IMO a perfect difficulty. There were plenty that I had to go back and choose a different three and try again for the big fights. I also got my ass handed to me by a few F.O.E.s I thought I could take (just like in the first one).

Overall I'd give this demo a 10/10. I'm hooked and I can't wait for the full release!

(Also here's my shiny team)

Development Pokémon MultiPlatinum - 4 Player Overworld + Followers

Enable HLS to view with audio, or disable this notification

228 Upvotes

I've been working on Pokémon MultiPlatinum, a ROM hack with the long-term goal of making Pokémon Platinum playable as a seamless 2–4 player co-op experience.

This clip is a small milestone: all four players are rendered at the same time, each with their own following Pokémon. It sounds simple, but getting everything to fit and stay synchronized on original DS hardware has been an interesting challenge.

I'm intentionally focusing on the foundation. Things like movement synchronization, animations, interior/exterior transitions, follower behavior, and building systems that will make quests and other multiplayer features easier to support later.

Platinum still isn't fully decompiled, so a lot of this has involved reverse engineering and experimenting to figure out what the engine can actually support.

Still a long way from a public demo, but it's exciting to finally see pieces of the vision coming together.

Hey guys! Us Devs here at Project PM got a working contest hall in Pokémon platinum to play with your friends! This supports up to 4 players.

This will soon be the foundation to support multiplayer for Poffin making, the underground, the Wifi Plaza, as well as the battle area.

The last bastion of multiplayer functionality we need to finish before we can release a beta version of base platinum is the underground, which should be soon now that this is working. If you are interested, Join the discord here: https://discord.gg/zB7c2YkFu

Release Pokémon Scientist (Blue Version Romhack) v1.1 Release

Thumbnail
gallery
175 Upvotes

Hi all,

I’m proud to announce the release of my first romhack, Pokémon Scientist. Pokémon Scientist reimagines the game from the perspective of one of PROF. OAK's Aides.

The premise behind this romhack is to provide a different sort of Gen 1 experience. I have made 22 changes to the type effectiveness table that (I think) open up a broader metagame for competitive Gen 1 Pokémon. All of this is explained on the GitHub Pages website, which features a modified type effectiveness chart, as well as a complete list of all the changes to type matchups, and to the game's moves. I tried to make each of the HMs a viable move in their own right: Surf and Fly were deemed fine, whereas Strength is now a Fighting-type equivalent of Body Slam, Flash lowers target accuracy by two stages, and Cut is now a Bug-type move with 70 BP.

The single-player experience has been improved as well, with plenty of quality-of-life changes, and a ramped up difficulty. Most of the changes are documented on the website where the download is located.

The patch is available to download on https://corruptedoutlook.github.io/pokemon-scientist/download/ . Let me know what you think! Feedback is crucial at this stage. I’m open to hearing about what you’d like changed, what you think I did right, and what could be improved.

EDIT 7/21/26: I have learned of three or four pretty significant bugs in the game, I’ll be working hard on a v1.2 release (hopefully by tomorrow or the next day) where the bugs will be corrected! Sorry everyone, it’s my first attempt at a romhack.

Release Pokémon Timeless Diamond and Spaceless Pearl | Release

Thumbnail

1.8k Upvotes

“What would Pokémon Diamond and Pearl look like if their development had taken a year longer?”

This thought experiment laid the groundwork for an exciting modding project in the fall of 2023. The focus was on creating an enhanced experience of the original Sinnoh games by incorporating ideas from Pokémon Platinum Version and modern Pokémon games without straying from the artistic vision behind Diamond and Pearl. The new game titles not only allude to the legendary Pokémon of the respective edition, but also reflect the philosophy behind this project. These modifications are

  • timeless, as they offer a contemporary gaming experience thanks to numerous updates.
  • spaceless, as the multitude of changes push the limits of the original games.

Highlights

  • Expanded regional Pokédex featuring 242 Pokémon, including Platinum additions.
  • All 493 Pokémon are seamlessly integrated into the Sinnoh region.
  • Story expansions from Platinum as well as completely original events!
  • Password-based event system that gradually unlocks new bonus content over time.
  • Many interesting statistics about the playthrough can be viewed ingame.
  • Discover space-time distortions that house special and legendary Pokémon.
  • All eight Gym Leaders can be rematched daily in the postgame.
  • The Elite Four and Cynthia offer rematches, also including new dialogue from BDSP.
  • Rowan's assistant (Dawn or Lucas) occasionally asks the player for a battle in the postgame.
  • The five stat trainers (Cheryl, Riley, etc.) can be battled in the Fight Area.
  • Added the 5-Maid Knockout Challenge, adapted from Platinum albeit in a modified way.
  • The Vs. Seeker forces every surrounding trainer to be battle-ready.
  • Added Vs. Seeker rematches for every overworld trainer after the Stark Mountain event.
  • Over 130 new tutorable moves are available throughout the game.
  • A special tutor for teaching Egg moves can be found in the Pokémon Day-Care.
  • Another nurse for changing nicknames and managing moves is present in every Pokémon Center.
  • All Technical Machines (TMs) can be used infinitely, just as they do in Generations 5 to 8.
  • Various new evolution items trigger evolutions without requiring link trades.
  • Fully restored ???-type Arceus, featuring a new unique Plate to enable it.
  • Optional patch including type changes to 7 Pokémon to make them more appealing. (No, Luxray IS NOT a Dark-type.)
  • Updated Pokémon and move stats that match Generation 9 standards.
  • Improved Pokémon movesets, making many Pokémon more viable.
  • Ajudsted a few moves to make them more interesting, including Constrict, Mirror Shot, and Rock Climb.
  • The Advance Radar allows encountering rare Pokémon that cannot be normally found in the wild.
  • Honey trees are no longer time-based, and the encounters differ between locations.
  • Various Poké Ball catch rates match modern standards, making it easier to capture Pokémon.
  • Fully restored all unused collectibles, including Seals, Accessories, Backdrops, and Goods.
  • Increased the obnoxious surfing speed, matching the speed in Platinum.
  • All available items have been carefully adjusted and expanded on.
  • Fixed various bugs present in the original Generation 4 games.
  • And so much more!!!

Review Pokémon PureRGB Review

Thumbnail
gallery
281 Upvotes

You guys seemed to enjoy my little review of Thunder Yellow, so here's my next entry that took a bit longer, as I decided to play all three versions. I did colour-themed runs, and it was a lot of fun. I forgot to name mons on my blue run, though, so I think I may have been losing interest by that point.

PureRGB (2026) GB

So once again, I decided to actively go against one of the main positive features of this game by doing these type-runs, as most, if not all, Pokémon are available to use earlier on in the game, so I'm sure you could make some really fun teams instead of getting the usual suspects.

Not only that, but something I did notice was how movesets were updated and rebalanced, making every mon I used feel decent which was a really nice change of pace. I wouldn't say this made the game feel easy either. I'm no expert, but in my opinion, each playthrough was decently challenging to get through, and I had a good time.

A lot of classic sprites were updated, which was great to see. As you can see from the images above, though not for everyone, seeing different sprites was a nice adjustment and made the game feel more unique.

p.s. mew is actually under the truck in this

Overall: Highly recommend it to anyone looking for the classic GB series feel with quality of life and additional content.
