How I Hacked Pokémon Emerald to make Pokémon walk with you

- I created a hack of Pokémon Emerald that allows Pokémon to follow behind the player in the overworld. I did this by using the C disassembly created by the people at PRET. By importing all the sprites Gen I - Gen III from Pokémon HeartGold and SoulSilver into this game I hijacked a certain already existing sprite and using the animation frames I added (recolored with a special process to use the Gen III palettes) let the Pokémon walk behind the player in the overworld. In the video I go over the process and discuss aspects of GBA programming, certain GBA graphics modes and sprite palettes.

How to apply the patch:
• How to Appy Game Hack ...
In Pokémon Emerald Chaos Ambulation all Pokémon Battles and Encounters are randomly chosen from the 386 Pokémon but are at the same level as the original Pokémon would be. For example, a level 5 Ralts could become any Pokémon at that level, with all the associated moves of that new Pokémon.

This hack should be fully compatible with existing save files, so if you have a .sav file on an emulator then your game, after being patched, should continue to function as normal.

One of the original concepts behind Pokémon was to have monsters travel with you and explore the landscape of the world. Don’t know why they scarcely use the follow function.
Space I assume.
Apparently it was intended for GSC. We even have the placeholder sprite for the mechanic, which is a sprite of Imakuni. Imakuni was also one of the DJs in the Radio Tower, in place of Mary I believe.
That profile Pic, I miss old CZcams
Not enough artists maybe? They're a big _multimedia_ franchise but their team is still very small. Fwiw.
No, the main is to collect them all, and pay to Nintendo to collect them all 😎
This should have been a feature in every game
Despite all the messes, I was glad they can follow us in Scarlet/Violet, but the different walking speed is super annoying.
It's realistic, same as the realistic Pokemon sizes, should've specified in your suggestions Pokemon fans
@@mariotheundying I'm not sure people buying Pokémon games are looking for realism in anything else other than the size of the creatures
@@LoScorpioneRosso1 people said "add the real sizes, be realistic!" So they did, both statements
@@mariotheundying It's actually still wrong, because the speed has to be the same of the player's avatar, not the one of Miraidon/Koraidon. This would imply that fast pokémon would only run in real life without being able to slow down to the same speed of walking people, while slow pokémon are stuck to even slower movements than the human walking speed. And still, this doesn't apply to some pokémon like Talonflame, that goes slower than the human character despite being a fast pokémon. Let's call this as it should be: they didn't care about setting a staged speed for all of them and just did things randomly, so now you have either a creature that has to catch up to you or returns into the pokéball, or creatures that overshoot and you have to catch up to them. About the size it's not really a call for realism, it's just damn idiotic to see a Wailord of the same size of a Sunkern.
@@mariotheundying Walking speed has already been an issue in both BDSP and SwSh. People were specific about it in their complaints, gamefreak just isn't very concerned with delivering a polished product anymore, as evidenced by the atrocious release state of their recent games.
“I changed something, did you catch it?”
*Chooses Entei as starter*
“That’s right! I moved the bag one space over to the right!”
We’re getting spoiled with all these extra gen 3 features!!! I’d like to see this ported to FRLG as well. Would be a great addition to the Plus rom hacks out there!
Ahh yes! That would be the motivation I need to finally try a frlg nuzlocke
Pokemon Yellow had Pikachu following you around, so it's sad that you didn't have that in the remakes.
Pokemon radical red( a rom hack of fire red) has following sprites for most pokemon
FRLG are the remake for Red and Green. Let's go is the closest to a Pokémon Yellow remake.
@@dinoboi55 I dislike radical red because well i don't really like super hard romhacks, i just prefer playing the ones with vanilla based difficulty.
And yes i know they have difficulty options to make it easier, that don't change the wack movesets and teams though, still got stuck on misty for hours then gave up.
I had no idea anyone reverse engineered these. Not that it would be necessary because emulators are really good now, but it'd be interesting if someone ported these so you could run them without an emulator. Maybe even merge them all into one game with the different story lines as chapters.
I’m surprised we don’t have native 3ds and vita/switch ports as of now.
@@yevgeniylankin7032 I'd love to see them all ported to as many systems as possible. Might have to look into what it would take, because I'm sure the code in its disassembled state could use a good refactoring for generic usage.
Man, just imagine what fans could do if they got ahold of the official source code from Nintendo in another giga leak, full on source ports of the original gameboy games and gameboy advance games would be fucking incredible, I mean I don't think they could really improve all that much outside of gameplay stuff like making it a single game idk something like Pokemon: E/R/S Evolved with all the Pokemon in their respective spots from each game and able to be caught in one save file (with an options menu to pick which specific Pokemon availability you want, of course with a 4th option having all of them equally spread throughout, plus the missing Johto Pokemon to complete the Gen 3 dex, and of course the event items, essentially what I imagine unless they want to implement trading and version differences as options via a single game session which sounds pretty difficult though it'd be amazing and the most 'vanilla' way to achieve having all 386 Pokemon available without altering locations and adding ways of getting the other starters and legendaries/mythicals who may not have specific in game events like Mew in Gen 1 or Jirachi in Gen 3 who were given away instead of being able to be normally caught at an in game location like Gen 3 Faraway Island and Mew) and I imagine multiple save slots and possibly even communication between said slots could be possible with a decompilation remake of the classic Pokemon games. Not to mention anyone who made that could definitely make it possible to trade/tranfer Pokemon between Gen 1 and 2 Remakes/Source Ports (not sure which or if both are technically right) and the Gen 3 one, finally adding the thing that sadly couldn't be done back in the 2000's. Like I said though since pretty much none of the Pokemon games before Gen 6 have any frame rate or even visibility issues not much aesthetically would likely be different, but I think the perfect experience with these games could and definitely would be possible granted dedicated fans put in the work and we get a leak with the source code for any/all of the Pokemon games like how Super Mario 64 and Ocarina of Time's source code were leaked. This is slightly unrelated but I really, really hope Gen 6 and 7 get their source code leaked someday, because source ports of those games would be amazing, they could make the textures look as good as possible, drastically increase the frame rate (which the 3ds games are somewhat infamous for) and increase the aspect ratio which since they're 3d games would likely have a more drastic and better result than the 2d Pokemon games, not to mention I imagine fans would do things like add the national Dex to those games, along with an option to change the encounters to include the missing Pokemon either throughout the main game or in the post game similar to a lot of rom hacks, and also hopefully the option to change between the different version's encounters, and a 'max' option which allows you to catch em all in the regions dex. (Also, since I'm throwing out ideas, multiple save files and dedicated option in the menu to trade between Pokemon saves would be fucking perfect, I guess it'd be fine if remakes on PC just gave you the option to switch between the two versions, but that'd be lame as shit when multiple saves, dedicated trading possibly with the option to connect to another via the internet and trade similar to how some emulators are able to do netplay with someone potentially states away, hell maybe they could even implement a 'GTS' system into the first three generations via these hypothetical source ports
@@theleonpasta7336 A lot of the reason why they didn't include them all for each game was size limitations of the platform and the cartridges themselves. They could certainly include a lot of them, but as time went on they grew a bit more than the portable platforms allowed for. Now they could easily get all of them in one game and with full 3D graphics too. While backporting to the 3DS would be cool, I'd prefer to not be as limited and just look forward to bigger and better platforms. As for SM64 and OOT, those were actually reverse engineered, the source code wasn't leaked. They are remarkable projects and part of their goal was to make it possible to regenerate the original ROM from their reverse engineered copy, and you can indeed do that. Because of their immense work there have been some really cool forks where they've fixed bugs and slowdowns in the original games even allowing it to run on the original hardware in a fixed state. You should look up the SM64 port to PC and give it a play.
@@theleonpasta7336Something i would really want is a widescreen option while maintainong the size of the sprites (which with would require doing new upscaled sprites) and/or an option to zoom out the camera to match the resolution of the screen, so you have widescreen with the same original sprites. A beautoful game made even more beautiful ❤
Have you talked to the developers of Pokemon Quetzal? They have follower pokemon in their RSE hack and might be able to give some tips with debugging
Apparently the follow Pokémon mechanic was intended for GSC, which would make sense considering that it was released after Yellow. We even have the placeholder sprite for the mechanic, which is a sprite of Imakuni. Imakuni was also one of the DJs in the Radio Tower, in place of Mary. I believe most of Yellow’s emotion bubbles are unused in the final too
So _that's_ why they added it in the GS remakes!
Imakuni was also a special fight in the GBC Pokemon Trading Card Game who rewarded you with what were easily the worst cards in the game.
You got proof of this?
@@ChangedMyNameFinally69 it’s stated on TCRF on the GS Development page on the unused sprites section
@@solgaleo3533 Ah I must've forgotten that. I wish Imakuni popped up as a side character in the games, LgPe would've been the perfect opportunity. Surprised there was never a Pulseman cameo either.
This user was sadly recently assassinated by nintendo for copyright infringement
This is criminally underrated. I love this so much
Solid mod addition to the game, just adds to the experience
It would be spetacular if you continue to improve it like maybe finding a way to solve the color bugs, some follower behaviors on the overworld, like making them reflect on the water, getting properly some overworld structure layers etc
Maybe adding some interactions with the follower.
It's already a amazing addition to the game, i'm already re-playing emerald with this mod, i hope for more stuff in the future
As someone that grew up with gen 1, Red being my first, I love seeing younger people do more with the older gens ❤️ emerald is probably my favorite Pokemon game of all time
Not to sound self-centered, but I think this was made for me, and others like me, who find this oversaturated catalogue of romhacks --unappealing overall-- or maybe demotivated is a better word, because many of them are appealing and really catch your eye. So as to not undermine them or trample on their passion or the hard work and effort they put into them. But that's the reality of it, at the end of the day.
I think I've just been desperately looking for a Pokémon game or romhack that captures that eye-catching quality like these original gen 3 games had, which can also keep my attention without having too much going on. Simple is better. Less is more, as they say. Every so often, I try again and find a nice-looking new RSE hack, but lose interest for some month(s) or even years. . .
Because lately... it feels like, just so overwhelming with all these romhacks being made. I'm sure they're great. They look amazing and make me want to play and finish them but I just don't ever have the time. Because of that, I've wanted to just set it all aside and get a more vanilla nostalgic trip/experience of playing a gen 3 game. More pure I guess. Whether it's Ruby, Sapphire, or Emerald. And I think this is perfect for me right now. To really satiate this unfulfilled feeling I keep getting when I think about these games and try to replay them as romhacks, and in a way I guess give closure to these nostalgic memories of that first Christmas when I was 6 playing Sapphire for the first time, and the many times I played and replayed all 3 games growing up.
Thank you for what you've done with this, and thanks for giving us a way to play it, instead of just being something you're showing off for views and clout but don't want to share for whatever the reason would be.
You took a simple thought. A brilliant idea and put in work to create perfection. You made something beautiful and I will thoroughly enjoy this while I'm on vacation from work for another week, and hopefully after that whenever I have time! Kudos to you, and cheers!!!
Any chance to make the changes open source? A friend and I wanna try and do something similar with FRLG.
I can't tell you how much I love this. I'm so grateful you've made this. I'm probably picking up a Miyoo Mini+ soon and so I thought I'd dig into rom hacks and patches and just happened to google to see if follower pokemon was something anyone added to gen 3. Follower pokemon were one of my favorite things about HG and SS and I've always hoped they'd bring it back.
I've never played a randomizer or a done a nuzlocke before (as a lifelong pokemon fan) but I'm currently doing a test run with your hack and it's SO MUCH FUN. Thank you, and thank you for making this video showing how it was made.
Gen 3 is my favorite generation. I love the hardware of the GBA SP. Kanto and Hoenn are amazing reigons. And the pixel design is timeless. I was able to get a full hoenn living dex and using my two emerald copies I was able to get the Johto starters. I'm impressed by your programming work. Gen 3 would be more complete if this feature was added
Having my pokemons to follow me was also one of my favorite things about Soul Silver, and now watching this feature being added to my favorite pokemon game is awesome. All the hacking and patching explaination was really interesting :)
8 seconds in "The best games by far were HeartGold and SoulSilver"
I take great caution not to use this word often but that was legitimately based.
Why do you even take "great caution" in the first place?
"Pokemon *Emerald Chaos* Ambulation"
We were on the verge of greatness. We were *_this_* close.
I think I'm wooshing right now. What's the joke?
@@purplegill10 He wanted it to be Pokemon Chaos Emerald Ambulation
@@purplegill10 Chaos Emeralds are powerful gems from the Sonic franchise.
I nearly typed it that way when I saved the patch file.
@@robertlupa8273 ...I'm so dumb. That's genius.
This was fascinating to watch. Thank you for sharing your creative process!
This is amazing. A dream come true! Thank you so much for creating this :)
This is incredible. Your hard work is unmatched
This is amazing ! Great job ! You just earned yourself new subscriber.
What a neat project. Companion Pokemons is something that I find to bring much more life and engagement to Pokemon games. Fantastic job!!!
This is beautiful! Seeing that someone was willing to do this to emerald, maybe this opens the possibly for gen 5 to get the same love!
For that to happen, there will likely need to be decompilations of their source code, which is difficult and slow.
Gen 5 already essentially has the mechanic in the code, at least in B2W2
@@crzyshrf9836 yeah I think you can have a certain Pokemon follow you in a npc's house
@@typachi yeah so logically it would make gen 5s very easy to do
I think the most difficult part would be to create adequate sprites for all the gen 5 pokemons, while importing the rest from HGSS
What you have done is fantastic! Not sure if there's such a thing for decomps (I'm pretty sure that there is), but you can change how the palletes are loaded into the game to load them dynamically. Meaning that instead of loading a static amount of palletes, you can have the game only load the palletes for objects and stuff that is shown in the screen. That should fix the problem with overlapping colors like the tall grass animation
Knowing most of this gba stuff already from a class I took in college, this is super cool and provides a brief overlook at how developing for gba works, very cool stuff!
what was the class about
@@Samir-rd8xp programming on the GBA, called Media Device Architecture
wow man why are you so underrated, this is incredible work
Love this patch! I would like to report some errors like you said.
1. The pokemon does not come out of a pokeball like you said in the video. Actually, I don't mind this one, but the pokémon should not appear inside a building, NPC or any other overworld sprite.
2. If you enter a building, specially having the pkmn by your side, the sprite stays aligned with you and goes through the building instead of returning to the ball or dissappearing.
3. When you walk and turn, at some angles and for a fraction of a second the pokémon glitches and looks where it shouldn't. That does not happen in your video so it may be a regression.
I've only played it for a couple of minutes and I spotted those errors with my starter (Mudkip).

The Game Corner Bug.
Did you have a glitch with the first gym? After I beat it the game bugged and put me in some black void
@@johnpoku9854 No but I'm not surprised. A friend of mine got stuck a couple of times after normal trainer battles in the mid of the game
T T
He did not save the game but he lost interest on this patch afterwards.
your humour got a lot of genuine laughs outta me lol
great video, absolutely keep up the good work
This looks so cool!
Thank you for making this, I will definitely be playing it in the future
Amazing rom hack, I’ll be beta testing the entire project just like the good old days. Thank you so much ☺️
It’s interesting hearing about the GBA and how it works being used to how the SNES works. For example, while transformations to sprites are possible by default on the GBA, to do it on the SNES, all background layers are unusable, meaning mock backgrounds are achieved only using sprites or HDMA
Bro the amount of work you did is mind blowing! Congratulations!!!!
Such a cool project, congrats
Great video, man. I'm just getting into coding and this stuff is a huge inspiration!
No negativity toward the hard workers at GF, I mean this in the best way possible: I wish that Game Freak could spend as much time putting detail into the Pokémon game as this ONE PERSON did by himself. Not really in THIS specific situation because, as mentioned in the video, the overworld sprites didn't even exist at the time of Emerald.
I say 'could' because I genuinely don't believe it's their fault completely. There's probably so much back and forth between Nintendo and the PKMN Company, awful time crunches, and, at the end of the day, there is a budget. Which probably isn't as high as I think it might be.
We don't deserve people like you man. Fantastic job. Maybe I'll finally properply play emerald just because of your mod. Keep up the great work 😌
thankyouthankyouthankyou so much for making this
watching the process in the video was amazing
can't wait to download it since i was thinking on replaying Emerald again X3
Dude… Amazing!!! Incredible work and video
Really enjoying this on the chaos version, it's going to make caves far less annoying!
Wicked cool. Respect for your hard work making one of my favorite games that much cooler
This is amazing, very cool concept and brilliant execution. I know this might be way too much of an ask, but can you (or someone) please consider doing this for gen 5 as well. I love the gen 5 games and think that following pokemon will make them truly the perfect Pokemon games, I hope it would be doable.
Wow bro you deserve all the likes and subs. You’re a genius!! Keep up the good work!
every romhack should impliment this, you are a saint for figuring this out, please make this open source! every romhack ever would be better for having this!
You are insane this is great hope someone uses this code you made for their own Pokémon ( hacks )custom games.
I want to make this myself.
Good job and I will refer to this if I ever try implementing it myself, as a tutorial or something or a guide more like.
Impressive skills
Guys like you are legends. ,much love goes out to you and everyone who does similar stuff
I like your thought process. Gotta even the playingfield before comparing the games.
So, personal story: I distinctly remember as a little kid walking in the mall with my mom in the spring of 2005 when I saw this big shiny green poster for Pokemon Emerald outside a game store. I immediately went inside and begged my mom to get Emerald, she told me that I'd already had Sapphire and didn't understand what was special about Emerald.
I'd remembered seeing a commercial or something that showed part of the intro where the Pokemon run beside you while you're biking and I seriously THOUGHT that Emerald had added a Pokemon following mechanic in the overworld and I was SO excited for that.
Suffice to say, I was a biiiit let down when no such mechanic was actually in the game, so seeing this totally avenges the let down I felt as a kid back then! :D
Really cool! I would be interested in hearing more about how the Pokemon games' internals work, and how hacks like this are implemented.
Played this for 15 hours all the way up to slateport where the game glitched out and I got put out of bounds. Can't get back in either. I guess my playthrough is over. Great hack man :))))))
This is amazing!! Fantastic job!! 🔥🌊💨
He puts this into simple terms, which makes it feel easy, but this is actually very time consuming
Theres so many variables not apparent to the untrained eye, and even to the trained eye, it's difficult to move around the minor bugs the game retorts with by tweaking with the files (Ex., The minor lag and twitches the pokémon models do when the character changes direction while walking)
I absolutely adore this concept
Can't wait to support you moving forward
wow i never foresaw it sir...that you are the modder behind on that Ambulation i saw on the site... Nice work Sir!!!,,,,
Amazing! Beautifully Amazing! Thank you so much for this. I love it SOOO MUCH
Inkbox is not the hero we deserve, but he is the one that wee need !
This is a dream that comes true
So awesome, great work!!
another absolute banger video
Good job man, well done But the number of likes is small. If they knew how long you stayed to do this, they would be impressed
I played the first minutes on the game and i already have found a few bugs. I am sure it's an INSANELY large amount of work to have even reach this far and kudos. It's an amazing hack. So now to the bugs.
When the mon is at either side of the character when entering a room, it doesn't go in the ball and it just phases through the wall. Looking forward to a new update. HUGE fan!
Absolutely brilliant as always, id love to see more of the code while we are being walked through how you did it, but thats just me being nosey😂. Absolutely brilliant video 💚
Shit this video is from a year ago. Just noticed, my bad hahaha💚
Thats insane, gen 3 was my childhood and i always wanted to see something like this lol
There's a hack called pokemon quetzal, which also added the following sprites and without visual bugs, maybe you can pick some things from there to improve your mod 😉
Dude I just started that and it's the best ROM to date I've played. Want fusions but need a computer for it
Your work is really inspiring bro
Good job, this looks so cute.
Amazing work my man!
This is really cool and I wish I could learn to code video games like this
Nice video👍🔥, sure am gonna play the rom hack i got inspired and now im thinking of making a rom hack myself but i might just change .gba to C cuz i know a bit of C so it will be easier and then change it back to gba
I absolutely love how HeartGold and SoulSilver had that companion feature
Waiting for more updates. I can't wait for this to be fully playable as a patch I can use for my existing game. I've got 300 hours on emerald with my emulator. Very excited to see this finished. I play multiplayer, so I hope that it won't crash the multiplayer instances. If it can be disabled in multiplayer, that would be something I encourage you to check.
I don't think it's being updated
I have a huge bias for the heart gold and soul silver, even though they were not the first Pokémon game I played, so I love seeing this feature on other games!! Thanks
Man this was an incredible undertaking

I would love to try your work thank you bro your work is a true master piece ❤❤❤
Also, AWESOME with the shiny support as well
this is amazing thank you for your effort ❤❤❤❤
You... Absolute...... GENIUS!!!
this is dope.
really cool and very informative for an amateur programmer such as myself, although i feel like pokémon mystery dungeon’s sprites would better fit gen 3’s overworld
You're the one who made those cute walking sprites? OH MY! THANK YOU FOR YOUR HARD WORK! Your work cured my depression ❤️ and to all that continued to do the same man I love you guys!
the hack called pokemon quetzal have walking pokemon too and gen 8
Cool idea to expand upon this, mystery dungeon with turn based combat from the regular games.
With how much work you put into this, do you think you could provide any help or tips for me too? I want to add Following Pokémon to Pokémon Black & White and I'm not sure how to create and apply the script to the games.
Would it be possible to see what script you used? Did you use C# or C+? How did you add/stitched the script to the game?
What’s nice is a lot of Unova Pokémon have overworld sprites, either from the game itself, the Hidden Grotto mechanic or the Entralink Forest. Unfortunately, not all of them would be functional, as, like in HGSS with Ho-Oh, Lugia, Dialga, Palkia, Giratina and Arceus, the actual overworld sprite used when it’s an NPC is much too large, and a different 64x64 sprite is used. A 64x64 sprite is also used for some other Pokémon like Wailord and Steelix within HGSS.
Really cool hack, thank you!
Super interesting to see what goes on behind the scenes of ‘rom hacks’ thank you for bringing pokemon’s best feature to my favorite game!
Commenting to help promote your awesome channel
You did by yourself what Game freak can't. RESPECT!!!
Brilliant work!
Good job man!
This is great I always wanted to see pokemon Follow behind me in emerald much respect
This is great! Good job! Also, can you apply this to Sapphire?
The fact that your first Pokémon game was the best one was an instant like
Never actually played through emerald, but I think this might make me finally get around to it
This is amazing! I wonder if it'll work if I attempt to apply this patch to a ROM that allows you to catch all available Pokémon normally. If it doesn't, would you be okay with me attempting to create one myself? I'm not the most experienced ROM hacker, but I'd love to at least give it a try.
Outside of legendaries, it would be relatively simple with the available poketools online to edit what pokemon appear where. As for legendary Pokemon, unless you want them popping up randomly in the wild, you'd need to set up events either in pre existing places, like caves and such, or make new areas for them to wait for the player to arrive to. You could also have NPCs gift the player pokemon, like starters, with a few dialogue script edits I think (it's been a while since I messed with any of the tools).
I LOVE THIS SO MUCH THANK YOU
The bag and entei joke alone made me subscribe lmao
dude, i dont care thats its not perfect, you did a REALLY GREAT job in this hack!!
I love ur work and i will try it :)))
please more content like this, make a a series of messing with this rom or something
Any chance this could be made to be compatible with the Emerald Double Plus patch?
one thing that I found really nice about this, is that its compatible with my existing vanilla emerald save. I have a physical copy of emerald, a GB operator to copy my save file from the game(And a legal way to get the rom), as well as a gba flashcart to play this hack on real hardware.. I can continue playing my same file I've been playing with this hack. thats so cool
HG/SS by far not the best games plot/fight wise, but having Mons walking behind us definitely helped a lot. Best mechanic ever.
Note: If I wasn't so overfed on playing Pokemon Emerald (around like, 500 hours or more xd), I'd definitely play this one. Since It's just the Follower animations (for now), not enough to put me into the game again. But I hope to see updates on this, keep going!!
