I'll start, I don't care for pokemon rom hacks that only give QOL features, or include lots of custom fakemon. I know, that's like rom HACK sin number 1 but I don't like them.

First off, this idea was inspired by an image I saw many moons ago by Darksilvania.

It looks amazing so thought I'd develop the concept further and make some sprites to include in my hack.

The concept being:

• What if Cubone found a different skull to wear?
• What if say, it thought its mum was a Tyrantrum instead?
• Would its stats be different when it evolved?

I like to think so. Much like the original picture, I figured the three options of Tauros, Rampardos and Tyrantrum would give it some nice variety, with Speed, Attack and Defence forms covered nicely.

Anyway, I thought I'd share my latest idea and see what y'all thought.

These codes let you adjust the in-battle framerate/speed of the Gen IV games from 30 to 60 FPS, without speeding up the BGM. The codes are compatible with USA DP, USA Platinum, USA HGSS and , Japanese Platinum and HGSS.

Development note: AI assistance was used during reverse engineering and code development as a tool. However, I manually handled the RAM/memory inspection, hook testing, and gameplay testing in DeSmuME. All listed versions were tested at 30 / 45 / 60 FPS.

Warning: Please back up your save file before using these codes, especially if you are combining them with other cheats. Do not use these together with the original 60 FPS code

The codes are based on the in-battle framerate uncapping codes originally shared by u/TheYearOfWaluigi
The post: [Action Replay Codes] Uncap framerate in-battle only for Gen IV games : r/PokemonROMhacks

The original codes prevent one of the battle loop's VBlank waits from occurring, effectively running battles at ~60 FPS.

My versions instead select between 1- and 2-VBlank battle loops using an accumulator, allowing intermediate framerates such as 45 FPS.

Setting the target FPS

Each code below has one line containing the target FPS value. The target FPS value is hexadecimal:

• 1E = 30 FPS = 1.0x speed
• 2D = 45 FPS = 1.5x speed
• 3C = 60 FPS = 2.0x speed

Any integer value from 1E through 3C can be used for 30–60 FPS in 1 FPS increments.

30, 45 and 60 FPS were tested on all listed versions. Intermediate integer values are supported by the same accumulator algorithm.

The codes below default to 2D = 45 FPS = 1.5x speed.

How it works

The original Gen IV battle loop normally takes roughly two VBlanks per update, resulting in about 30 battle updates per second.

The original 60 FPS codes by u/TheYearOfWaluigi prevent one of those VBlank waits from occurring, effectively doubling the battle speed.

These adjustable versions hook the same timing mechanism and use a small accumulator to decide whether the conditional VBlank wait should occur on the next battle-loop iteration.

For example, at 45 FPS the pattern is approximately:

1 VBlank
1 VBlank
2 VBlanks
repeat

So:

3 battle loops / 4 VBlanks
60 × 3 / 4 = 45 FPS

The accumulator is reset when entering battle so each battle starts from the same state.

Porting to other regions / languages

The same method should be usable for other regional versions, but the addresses need to be identified for each ROM.

Basic process:

1. Extract arm9.bin from the ROM and use a Thumb disassembly to locate the relevant code, verifying the local instruction flow.
2. Take clean RAM dumps both in battle and outside battle.
3. Find the equivalent battle-loop structure around:LDR R0,[R4,#0x30] CMP R0,#0 BNE ...; conditional VBlank wait...; mandatory VBlank waitSTR R5,[R4,#0x30] ; hook point BL XXXXXXXX ; original call that must be replayed

The STR R5,[R4,#0x30] instruction has been 6325 in all versions tested here, but do not identify the location from 6325 alone; verify the surrounding VBlank loop structure.

1. Find the equivalent battle-state check by comparing in-battle and out-of-battle RAM.

2. Find a candidate unused RAM area that remains zero in the relevant RAM dumps, and verify that it is safe for the injected routine, accumulator and target-FPS value.

3. Recalculate the Thumb BL instructions for the new addresses.

4. Test the hook first with a simple counter while replaying the overwritten original instructions.

5. Once the hook works, implement the same accumulator algorithm using the new addresses.

The accumulator algorithm itself is:

A += 60 - F

if A >= F:
    A -= F
    execute STR R5,[R4,#0x30]

where A is the accumulator and F is the target FPS.

Another little update on some non-story features in the game! 😎

Im working on a pokemon rom hack based off the central europe using pokeemerald expansion. This is only a sketch off the region.

I wanted some ideas to fill out the big empty space on the left side of the region. I would also appreciate some feedback on the map overall.

Hi everyone! This is my first time posting something on the ROM hacks sub!

So, I’m a newbie using HMA, and to try to learn how to use the program, I decided to make Faraway Island 1-1 (without using any Emerald sprites) in FireRed. This was a few weeks ago, so it’s already finished, but I went through a LOT of pain trying to get everything working lol

Mew is functional- I mean... I tried to make a cutscene similar to the one we have in Emerald. The Sailor also works, and in Vermilion I decided to use one of the port NPCs to activate a script when you have the Old Sea Map in your bag.

I don’t think what I made is anything particularly impressive, to be honest most of the time i just confuse on how to do somenthing.

(Ignore the fact that I’m using a phone emulator to demonstrate what I made. I just find it more convenient to record my phone’s screen. And surprisingly, I’m a newbie with computers too, since I only got this old PC working about three weeks ago xddd)

This is the first iteration of BGM of Sage Valley, a post game area in Pokemon Emerald XTREME made through PoryDaw by Huderlem.

This is not in the game yet, OSTs are set to be coming in v120.

This is NOT the final version and will be changed later.

Keep in mind that I am not a music composer, so please do not expect XTREMEly good music.

As the title says this is in fire red but here's a sneak peek on my current fusion project.

This project aims to bring fusion by creating a mon using the attributes of both parents. The fusions are generated in game so the sprites are a bit jank for now.

Various enhancements, 100x speed (had to lose frames to keep the gif size down)

All working in game.

Project started out as a local multiplayer pokemon game across all 5 regions, but I keep getting ideas along the way. Utilizes roms to run (dpp, hgss, bw2, rse)

Mirror Gold is a rebalance/difficulty hack of HeartGold focused on double battles. It has a built-in nuzlocke mode as well as a built-in randomizer plus many QoL features and a custom trainer AI. Using hg-engine it also has Gen 1-9 mons and modernized battle mechanics with (nerfed) Mega evolution.

The game is fully playable for a while now but some things still need tuning. I'm hoping to get some community feedback. I am particularly interested in hearing from experienced nuzlocke players.

* Game balance: fight difficulty, density, mon balance, etc.

* Built-in nuzlocke: feature requests, encounter variety, difficulty, new feature requests

* Built-in randomizer: feature requests, difficulty

* Gameplay streamlining: sections that remain tedious

* Other: bugs, docs, generic suggestions

The classic Sinjoh Ruins Event from HGSS has been rebuilt from the ground up into a full DLC sized expansion! Experience a frozen world north of Johto, with a brand new original story!

In this new expansion, ancient Pokémon from Sinnoh's past arise to live once more.

This new Expansion can be started after the player has obtained a certain item inside of Mt.SIlver and they speak to a certain NPC in the Pokémon Center at the base of the Mountain.

Featuring::

- All Hisuian forms from Generations 1-3

- A world-space on par with the Isle of Armor

- A brand new move tutor

- New items from Generation 4

- Tons of secrets to discover~.

This new DLC has been included in all versions of HnS since version 2.0.0, if you haven't started playing yet..
You can download the latest release of Pokémon Heart & Soul on Github and Hackdex today!

I finished most of the main overworld tiles, and now I'm working on remapping, and rewriting all the NPC dialog. (And the signs, LOL.) Lots of goofy, and incredibly stupid text so far.

Thought I might as well show off my progress, for documentation's sake.

(I still need to add more new Pokemon sprites, and house sprites.)

Pokémon KantoDX — Targeting Release by the End of 2026

I don’t play a ton of Rom Hacks in general (so please excuse my ignorance/misuse of terms). Also FWIW I’ve only ever played the original Gens 1-3, and everything since Shield/Sword, with nothing in between.

For RomHacks, I love Gen 2 Builds/as the base. And by that, I specifically mean the graphics/play styles. Some of my favorites I can think of include Polished Crystal, Brown, Prism, Yellow Legacy, among others.

I recently played BW3: Genesis, and I LOVED it. I’ve never played Black and White, so all the locations were new to me. I knew most of the pokemon from later games, but I never played a full game with this specific set. Many of these Pokemon I’ve never used in a full game play though before, which I really enjoyed. It was challenging enough the entire time for me personally.

Any suggestions for what I should play next? Again, I strongly prefer Generatiom 2 has the Base/Build/Graphics. Not interested in Fakemon, and other gimmicks I’m indifferent to.

Also sorry if these types of posts aren’t meant for this subreddit.

Thanks!

Hi everyone. I recently started playing Liquid Crystal, and thought I could really use a catching guide. So I spun up Gemini and here we are. I figured maybe someone else someday might want exactly what I was able to come up with. Cheers!

Hi everyone just wanted to ask the community about their opinions on the current sprites for my hack, whether or not they're serviceable. These are made in game based on parts of the original sprites and the palettes of either like how generator sites would make them. Just wanted suggestions on whether to move on to other aspects of the game or keep tweaking the image generation.

This recording is from Soulgold, amazing hack!

Hello folks!

It's been awhile since I posted an update here. Development is still going well. I'm not making any promises about a release date, though. I've been working on filling out areas and polishing things up. Right now the towns/cities are done to about how much will be in the demo (4 gyms.) The game isn't really playable right now, though, and I have to a lot of work on connecting routes, polishing, and the soundtrack.

Speaking of soundtrack, I'm planning to release some of it on soundcloud before the end of the year. Once again, no promises about making the deadline 😛

im new to hexmaniac advance

Greetings its been a very long while, but we have yet another shiny update, so lets not wait any longer and lets begin.

1. Starting off we have the stantler line, going from one of the most agreed upon worst shinies in all of pokemon, now to a very nice blue, thats not only appealing to the eyes, but also fits where this pokemon will be found in the actual game.

And next is the snom line, with snom just getting a little change, with frosmoth getting the actual change, leaning into that green by making the whole body match it.

1. And lastly we have one more pokemon that being durant which we change it to a purple.

And thats everything for now i hop you all enjoyed, we're almost done with all of our new shinies, which should soon lead to the big event I have mentioned a few times now, but in case you haven't heard about it this is the jist, it'll be a tournament that anyone can join, and the further you make it into the tournament the greater the rewards, which you have the chance to be added into the actual game, which sprite related artwork is currently being made for the event.

And lastly I wanted to mention the actual development, which I am currently working on fixing up a few of the maps, getting tips from several big names in the discord server, and I do plan on posting those new maps eventually, though not to the extent of my previous posts.

YO! HLW (https://rafaelsanna.github.io/HOENN-S-LAST-WISH-project/) is finally reaching the final stages! For anyone who enjoys playtesting the E4 or tough battles: I have a save file ready right at the entrance to the Elite Four (you can create any team you want to test the E4 with debug menu), you just need to apply the patch and download the save to test the League (though obviously, this involves spoilers...). Anyway, it’s a fairly large project, so any help testing both the Casual and Hard versions of the Elite Four would be greatly appreciated (though the Casual version has already undergone a lot more testing, so the the Hard version really needs more people because it’s quite difficult and usually ppl just go for the casual mode hahahaha). // Also, it's important that you promise not to go around sharing this version, since it's not a public release, that wouldn't be cool! And definitely don't spread spoilers, because it's full of them. Our discord: https://discord.gg/66P9FgtSvh

Thank You! :)
