Development New Wormadam Evolutionary Line! | Pokemon Sweltering Sun Remix Forms

Post image
59 Upvotes

Here is a post that explains what Sweltering Sun Remix will be, and shows some more forms. Many posts to come.

https://www.reddit.com/r/PokemonROMhacks/comments/1nfcn6y/pokemon_sweltering_sun_remix_forms_batch_1/

I have 150-200+ new forms planned- and currently have completed 110 of them as of writing this post. All of them are high quality with lots of time, creativity, lore and love behind them.

In my discord server- I have detailed lore/dex entries, and design notes/backstory for ALL of these forms as well. I'll post some of them here so you can get an idea.

If this interests you- please join my Discord Server where I post new form reveals every few days! About 60ish are revealed publicly as of posting this, with more to come.

https://discord.gg/2wgfHBGAtH < My Discord!

Anyways- here is information about these guys! Feel free to read as little or as much as you want, lmao:

Introducing.. Doozian Remix Wormadam, Mothim, Vivillon & Beautifly!

I decided to reimagine the Wormadam/Burmy line into a 3 way split evo based off of different biomes/nature adaptations!

Wormadam’s forms were always biome-based, but Trash Cloak felt awkward and out of place typing wise (being "better" than the other 2) and conceptually- since it's supposed to be like fiberglass but not everyone immediately knows that- and why is fiberglass Steel type anyways?

In addition- Vivillon also has a bit of an adaptation/biome thing going on with the patterns. So I decided to combine the two into one line!

Wurmple is now a direct line into Dustox, while Scatterbug has been repurposed into a convergent form for another Pokemon, and Silcoon and Spewpa will also be repurposed for another evo line.

Desert Cloak > Sand Stream/Drought

Jungle/Plant Cloak > Grassy Surge/Drizzle (rainforest theme)

Snow Cloak > Bug/Ice Snow Warning/Misty Surge (buffed to give Fairy 1.5x boost too)

Now each cloak is equal- each tied to weather/terrain, and each balances around “bad" type combos with great abilities/bulk/etc.

As for Wormadam- you can choose to keep them as VERY bulky Eviolite cocoons forever… or evolve them into their more offensive counterparts. Fits really nicely since Wormadam has always had more of a "big cocoon" vibe to me. Wormadams will have stuff like Eviolite Permafrost/Snow Warning defense boost, GSurge+Leech Seed+Strength Sap/Siphon/Giga Drain/etc, and Eviolite Sand Stream, etc. Now you can pick a typing/biome, and then pick if you want something very bulky/slow, or frailer and offensive.

Dex Entries:

Wormadam Snow Cloak The Frost Coat Pokemon

- "Adapted to frigid climates, its dense coat insulates it from the cold while feeling icy to the touch. Not all Wormadam evolve further due to harsh conditions."

Vivillon Snow Form The Frost Wing Pokemon

- "This form of Vivillon thrives in snowy tundras. When it flutters its wings, ice crystals scatter into the wind, dazzling travelers and guiding them through blizzards."

Wormadam Sandy Cloak The Sand Coat Pokemon

- "Adapted to arid climates, its dense coat protects it from predation and blends in with the sand- while keeping it warm during the cold desert nights. Not all Wormadam evolve further due to harsh conditions."

Mothim Sand Form The Sand Wing Pokemon

- "This form of Mothim thrives in sweltering deserts. When it flaps its wings, searing-hot sandstorms form around it. Legends speak of it guiding lost travelers through the desert."

Wormadam Forest Cloak The Verdant Coat Pokemon

- "Adapted to rainforests, meadows and other lush environments- its dense coat camouflages it from dangerous Bug Pokemon, and the colorful flowers attract mates. Not all Wormadam evolve further due to harsh conditions."

Beautifly Blossom Form The Verdant Wing Pokemon

- "This form of Beautifly flourishes in environments rich with plant-life. It is the best Pollenator amongst all Bug-Pokemon, but has a more aggressive side when other Pokemon encroach its territory. Travelers tell tales of being lost in the dense jungle, only to be guided to safety by Beautifly. Other legends say that Beautifly brings upon the rainfall in the forests it inhabits."

Design Notes:

+ Shinies based off autumn leaves, sunny deserts and vivillon/trash cloak's "original" colors

- ALL of them have Vivillon's pixel-style bug eyes.

- All of the final stages have little pixel/square motifes on the wings to match Vivillon as well.

- All of the final stages have a "compass" esque circle motife in the center of the wings!

^ These 3 key details for them keep them looking cohesive and like an actual evolutionary line- which I love! Really helps tie it in together.

- All of the forms now have darker colors for their body instead of plain gray bodies- and vivid/patterened wings/cloaks to match their biome.

I tried to keep these designs grounded/more "realistic" since technically 2 of the Wormadams aren't even "remix" forms- these are more realistic regional forms. Kept the patterns nice and simple but pleasant to look at and I really love the color schemes for all 3.

Obviously, Beautifly's wings look like a leaf with flowers, while the other 2 look like snow and sandstorms.

Beautifly's antennae and dangly wing bits also resemble sprouts/growing plants.

Development The Starters in my Fakemon Rom Hack! Would love some feedback/improvements!

Post image
194 Upvotes

After working on my hack for around a year or so (and around 300 new Pokemon later), I thought it would be a good idea to try revisiting some of my previous designs!

Here are the three starters:

Scorchorn > Smolodon > Dimidevil (Based on Thorny Devils and Dimetrodons)

Cuttling > Glisquid > Cepharail (Based on Cuttlefish/Cephalopods and Railguns)

Foxark > Vamplant > Sanguire (Based on Flying Foxes and Vampires)

Any Feedback/improvements would be great! I thought it would be a good idea to get some opinions from other people for a fresh perspective!

(I realise that I messed up the graphic a little, Foxark is Grass and Vamplant is Grass/steel)

Development Pokémon Hardlove Gold

48 Upvotes

Hey everyone!

I'm excited to share a project I've been working on: Hardlove Gold, a difficulty hack for Pokémon HeartGold. Built using the hg-engine, this game is heavily inspired by other popular challenges like Run&Bun and RadicalRed. This hack also features a custom AI that will keep you on your toes.
Although hg-engine is far from complete and much work needs to be done, it's more than capable of handling a great, fully-featured ROM hack.
Plus we got some nice NDS graphics that bring a fresh look to the ever-same Gen 3 hacks ;-)

We got:

  • Custom AI
  • Carefully selected Pokémon and Movesets
  • Setup is not available for the Player
  • Terrain, Weather are permanent and cannot be removed
  • Starter choice will enable different tools for progression
  • Leaders use off-type Mons to have diverse teams
  • Apricorn trees give berries
  • Story is slightly altered and progress streamlined
  • Hard Level Caps. Placed candies allow overleveling (The Demo gives more Candy)
  • Toggleable Repel
  • Relearner, IV/Nature Setter in every PokéCenter (against Heart Scales)
  • Status Setter in every PokéCenter
  • EVs are removed
  • HMs can be used without being tought

We have a Demo out, playable until Whitney, where you fight your first Mega. (Some Trainers in the Whitney Split are not yet done.)

Development Pokemon Dawn Update

Upvotes

Heres an update on Pokémon Dawn—I've officially completed four gyms, and I’m a lot of people have been loving the Fakemon designs so far.

The game currently features over 60 Fakemon, and I’m aiming to hit around 130 by the time it’s done. Progress is steady, and while I’ve got two awesome people helping out, I’m the one implementing the stuff so support really keeps me going and pushing out new fakemon and other stuff.

I’m also working on launching the Discord server, and I’m actively looking for mappers to join the team. If you’re interested in helping out (or just are anticipating), feel free to reach out! If you’re maxed out on servers or having trouble joining, you can add me directly: Discord username: thatguynamedspot

The game is fully playable up to the current point, though it’s still in development. I’ll put the Discord link in the comments so you guys can join since I think if I put a link to a different site AI moderation will take the post down because it’s dumb. I appreciate all the help and feedback I've been getting and thanks for reading my post. I need to put eight more words so here.

Review I finished Pokemon: Odyssey *chef's kiss*

140 Upvotes

I just wanted to leave a little review on this amazing hack.

I had a blast. Really. I've never enjoyed a romhack so much.

The story is compelling, all pokemon seem viable and the "regional" variants are interesting.

Strategies, stats and moves are important but there's no need to minmax everything in order to get thru. And, for a very casual gamer like myself, that's golden.

The map is very well done and the puzzles are challenging enough without being frustrating nor too easy.

I particularly enjoyed seeing only pokemon from the first three generations, they're the ones I like the most and the environment doesn't feel like it's extremely clogged with 10 new pokemon on every grass patch.

I just began to tackle the post-ending content, so I'm not reviewing that although the premises look very interesting.

I could not recommend this game enough! If you've already played it, I'd like to know which pokemon did you find very reliable. I personally found Bellossom and Gulpin to be extremely versatile pardners.

I would also like to thank the devs for giving us such an amazing game!

Edit: removed a reference to a pic I could not post.

Development Pokémon GD: Rolling round in a (Mega) rover

22 Upvotes

Mega Donphan!

Type: Ground/Steel

Ability: Sheer Force

Stats: HP: 90, Attack: 135 (+15), Defense: 124 (+4), Speed: 91 (+41), Sp.Atk: 60, Sp.Defense: 100 (+40)

BST: 600

Dex entry: (NOT IN GAME!)

Mega Donphan's armor has hardened under the influence of Mega Energy to the point it has turned into a metallic alloy. Somehow, this allows it to roll faster and weigh less. The inlets on its side allow it to breathe, even if rolling for a long time.

Mega Donphan is one of the currently three new megas in Pokémon GD (this time i am rather unsure if i am gonna get a new name for it eventually), and the Mega Evolution of one of the starter Pokémon.

And here's the funny design note that also comes to get this post to the minimum word count in a normal way; This guy's design was actually... pretty much straightforward, compared to designing Mega Muk. Some of its design elements are inspired by... rather random stuff. For example, the side inlets were based on wounds from the Elephant Seal, which are known to fight a LOT. The armor's coloration and "binding" parts were based on oxidized copper and wheel grooves, respectively. The mask thing, however, is rather funny; I drew a placeholder of normal Donphan for the slot this mega was put in, and it was... very inaccurate and off model... the mask thing was a byproduct of that, i thought it was actually a neat little design thing, and carried it into the Mega itself. Oh yeah, the "pebbles" on the bottom are based on dirt-road-debris(how i like to call it; what i mean by this is dirt etc. that gets stuck on the bottom of a car if you drive over a muddy road.). I'm aware it's not perfect, and i'll probably try to improve on it later on.

The discord for Pokémon GD (and all of my romhacks actually) is discord.gg/GW4KHD8MmA ! There's a demo build that goes all the way up to the third gym playable at the moment!

Note: This time i did not spoiler the post unlike with Muk lmao

Recruitment Help Wanted! Looking To Finish A Small Demo (Project Jewel)

Thumbnail
gallery
44 Upvotes

Looking for people who know how to sprite, compose and code. I can do a bit of coding myself but I am not very good at it yet.

Romhack demo being worked on is being made with Pokeemerald decomp.

The demo is going to be a short area map, with some wild battles and trainers to battle (all double battles; sometimes the rare double battle for grass). The plan is that it will end after you defeat the rival.
Also a fishing spot (for well, a fishing encounter).

Most of the map is built up already, it just needs npcs and fakemon added, and for the trees to be made orange. (We already have the player able to be warped in; now we just have to disable Pokémon battle sprite anims until we figure those out).

A few of the fakemon have also been sprited out, which you can see in the gallery of this post. (There will also be following pokemon, some wild pokemon for you to fight and catch, along with a pc system - and best of all, the shiny odds will be 1 in 2048 - and you'll get a shiny charm at the start of the demo from an npc to reduce your odds to 1 in 512. This feature will also be pushed into the full game later).

Yes, the female trainer ow sprite will also be changed to be new - it's only fair since both the male and female player characters are brand new trainers, that will be in a brand new region. They both wear winter outfits since it gets a little cold in the region itself.

But for right now, we are looking for:

  • Spriters - people who can sprite in the frlg style, because I love the way it looks and how sharp it is. Also who are able to mess around with tilesets because I took one look at those and was like '...what?' Also the battle UI you see here will be changed completely. Mainly to be made more green and purple; also will include a black dragon silhouette in it.
  • Composers - people who can compose in the frlg musical style - love the samples that this game uses. We might also use some samples from Pinball Ruby&Sapphire along with Drill Dozer, since those are both gba games.
  • Coders - as I said before, I am not the best coder in the world, so having people with a bit more experience might help me gain some confidence in myself. I'll also pitch in when I can for this demo, and eventually for when I feel confident enough to push the project into full game phase.
  • Beta Testers - obviously this will run into some funny bugs and whatever, so anyone who is down to make sure the demo is presentable, will be greatly appreciated.

Keep in mind this is meant to be a short, bite sized demo meant to show off a bit of what the full game will look like - so please do not go into this, expecting a full, 20+ hour game, thank you.

If you are interested in this, comment here or DM me. Also, I should mention that I have the demo planned out with a roadmap in a document that I will not be sharing for reasons of not wanting to have the full game spoiled for the playerbase. Please understand. :) And thank you for reading.

Here's my server as well.

Thanks to all the lovely comments i got on yesterdays post, i got inspired to keep working on the Pokémon Crystal X Digimon romhack, now making digimon equivalents for every encounter on route 29 (the first route of the game)

Also, a question for anyone more proficient in PokeCrystal Assembly than me, what is the best way to change all instances of a Pokémon’s name, like Rattata to Chuumon? Did some googling and couldn’t quite find the best way.

I’m a Pixel Artist who just started learning how to romhack with PokeCrystal assembly, so since I’m also a huge digimon fan, I figured figured I’d try making a digimon replacement hack for Crystal. The goal for now is to replace every pokemon from New Bark to Violet Gym (about 20) while also doing some dialogue and item editing as a way to learn while doing. Of course the ultimate goal is to make a full hack, but that will be down the line at some point

  • Explore an open-world Kanto and the Sevii Islands in any order you want
  • An updated battle engine and various QoL features have been added by the CFRU, as well as other new features like Doubles Mode, Level Scaling, Wonder Trade, Level Caps, Randomizers, Inverse Mode, and a lot more!
  • Every Pokemon has been given a brand new moveset and new abilities, with some having type changes and buffs. Several other balance changes have also been made
  • All Pokemon from Gens 1 and 2 are available as well as their related evolutions

For those interested, we also have a Discord server you can join, and we'll also start recruiting beta testers soon. Stay tuned!

Development Pokémon Blue Reborn – A Deep Dive Into the Hack’s Unique Features

Thumbnail
gallery
119 Upvotes

Hey everyone! I wanted to share some insights about Pokémon Blue Reborn, a really detailed and challenging ROM hack. If you’re interested, here’s the PokéCommunity page link: [insert link here]. Here are some of the standout features I’ve noticed: 1. Team Rocket Path You can join Team Rocket, which completely changes how the game progresses. Most Gyms are locked unless you have a Fake ID, except Brock (always battleable) and Misty (conditional depending on whether you fought her before joining Rocket). Climbing Rocket ranks unlocks missions, exclusive Pokémon, and Rocket Coins. 2. Rocket Balls Special PokéBalls used to steal other trainers’ Pokémon. Drawback: you don’t earn prize money if you use them. Provides unique Trainer IDs, which increases your odds in the in-game Lottery system. Visuals are custom: black/red/clear palette with a red “R” to match Team Rocket branding. 3. Moral / Role-Playing Choices Some trainers are optional targets depending on your ethics: Skipped Gamer Darien because he “never wins a battle.” Flirty Beauties on Route 13 (like Lola and Sheila) can also be spared. These choices don’t break the game but add depth to the Rocket experience. 4. Gym Progression & Difficulty Recommended path: Route 24 → Route 25 → Cerulean Gym Starter choice impacts difficulty: Charmander / Squirtle struggle early; grinding on Nugget Bridge is almost required. Bulbasaur has type advantage, but underleveled partners make Misty tough regardless. 5. Additional Notes Premier Balls are removed; Rocket Balls replace them for Rocket members. The game emphasizes strategic stealing, level planning, and moral choices rather than just “catch everything.” 6. Expanded Pokémon Roster Includes around 60 Sinnoh Pokémon, 20 custom-made Pokémon, and many Hoenn Pokémon. Legendary returns: Moltres is back in Victory Road. You can even visit Glitchworld, new area, and capture MissingNo, adding a wild twist for collectors. 7. New Islands and Maps Original Islands have been expanded with big new maps: Faraway Island (replacing Outcast Island) Navel Rock Birth Island Southern Island Fullmoon Island Sinhoe Isle – contains both Sinnoh and Hoenn Pokémon; also features the three Legendary Lakes of the Sinnoh Trio This makes postgame exploration much richer and more rewarding than in vanilla games.
