NOTE: PATCHING IS REQUIRED TO PLAY THIS GAME!
We donโt share pre-patched rom hacks and roms โ sharing these files is considered piracy, and itโs illegal!
Hi, Iโm trying to load and play this on my iPhone using Delta. The file I got is a .rar file. I donโt know what to do next. Can you help me?
Hi there, VVinUP. It looks like you might be new to Pokemon ROM hacks, but no worries, weโre here to help. The .rar file needs to be extracted first. You can use any app that can extract .rar files. After that, look for the Theta Emerald EX patch file and apply it using a patching tool.
You will also need a Pokemon Emerald base ROM. One of the most popular tools for this is ROM Patcher JS. For the complete guide, we created this tutorial on How to Play Pokemon ROM Hacks on iOS with Delta Emulator. Hope this helps.
Hello there. I tried to patch Theta Emerald EX ups to base Emerald ROM, but the ups file doesnโt match with the base rom. Saying the CRC32 doesnโt match. May I know which base Emerald this hack rom used?
Hi YG, try using Emerald Trashman version in patching the game.
is it possible to play this on a macbook? the patching program is an exe so i dont know how to patch the rom hack to emerald otherwise.
Yes, I also use a MacBook, and mGBA is the best emulator for playing this game.
Hi ! Are there still Pokemon that evolve through Trading, (Machamp, Gengar, Trevenant etc..etc) or do they evolve by leveling up?
Hi, can anyone help me pls? I cannot patch this rom to its base rom
Hi Hien, thanks for coming here. You may check our patching guide here https://www.pokemoncoders.com/apply-ips-ups-patch-play-rom-hack/ or see this video https://www.youtube.com/watch?v=M3RnlWQWDHQ
I dunno if this page is still active but where do you download the compatible Emerald ROM to be patched with the UPS?? I had a pre-patched ROM once but I lost it just recently and the websites Iโve went were all now gone. Iโve tried patching it but it all doesnโt match with all my current Emerald ROMs. I hope you can help me. Thanks in advance.
Hi there Snow Hasegawa. Unfortunately, we donโt share information about roms. The reason those sites you know that youโve been getting your pre-patched files before are now gone is that they share rom files. Itโs illegal to share rom files and considered piracy.
Well thatโs really useful isnโt it
I Just download this because you can run indoor
Hi, Can anyone point me to the right ROM? Iโm having issues finding the right one that can be patched.
anyone know how to fix the freezing issue in tate and lizaโs gym? I froze on the first 2 trainers and this is my bad but I havenโt saved for a long time and really dont want to restart.
What are the list of Pokรฉmons that can mega evolved
theta emerald ex and theta emerald renev any difference? beside the number of pokemon and evolution stuff?
Heyo! How do i get the file into my MyBoy Emulator?
Hi I tried opening my pc ,but it just becomes a black screen. This means I canโt take pokemon from.my pc and thatโs really annoying because I have my shiny rayquaza in thereโฆ.if there is anything you can do to help please do
I would say that it is an excellent game, if they put the objects like Weakness Policy, Eviolite and some more it would be perfect
Double-battles are pretty buggy here. There are a lots of moves that freezes the game when done during double-battles. Pretty good hack tho.
how to stop infinite exp?
You can simply disable the cheat from your emulator. Which emulator are you using?
idk how to get it on eclipsemu
How to patch a file?
You might want to check our tutorial guide on how to patch a rom hack.
It deleted of of my TMs and HMs after defeating the 3rd gym, any help? If so please tell me because this glitch renders the game unplayable because I canโt teach any of my Pokemon Rock Smash so i cant play the game any further
The game freezes in the 7th Gym Leader battle when Tate&Liza send out a Bronzong, any help?
Could this be a bug in the game or do you have any cheats enabled? Be sure to disable them.
how to patch the .ups file??
Teleport cheats
Game not found
What do you mean? The download link is working well for me.
many of the other abilities doesnt work like โSHEER FORCEโ and โPURE POWERโ I tested the sheerforce on conkeldurr and feraligatr the sheerforce doesnt work and the pure power of medicham doesnt work and I dont know ifthe ability of scizor โTECHNICIANโ works too since the damage is kinda low with right nature and high level, pls fix it so that i can download the game again.
After battling in Battle Arena in Battle Frontier, I lost all my TMs/HMs and my items turned infinite. I read that thereโs a bug in battle tent that make you lose all your tm/hm but iโm in battle frontier. I grinded my team to level 100 to get the symbols but now i canโt teach them new moves.
that is the reason why you shouldnt go to battle tents because itโll make your hms,/tmโs disappear. so try to avoid battling there
Is easy just use All TMs/HMs cheat if you lose them all.
Does this rom work with VBA link?
Where do I get the zip file? This oneโs rar.
what does level 250 mean?
Max level is 250
It keeps saying โThe Patch does not match the fileโ, Iโve tried with multiple different emerald roms
Same Here. Anyone know a fix for it?
hey i imagine you already figured it out but if you check the ignore button on the NUPS button on the left side of the screen it will work.
There`s something in my mind, Does pokemon theta emerald Ex still make legendary pokemon appearance as a [black orb] instead of their origin look like rayquaza, kyogre and main legendary in Emerald. when it come to others legendary, their Appearance are a [Black Orb]
annd one more, how i can contact the developer ?
Hi pokemon coders i got a problem that is all the TM and HM in my bag are gone and without HMs i canโt complete the game.
Sorry to hear that pal, I hope you saved your progress before applying the cheat. Alternatively, you can use TM/HM cheat.
How can I get the zip file?
Can we, kinda import our saveโs from the older pokemon emerald GBA into this version of Pokemon emerald? Also how to actually do it?
This might sound a good idea but I doubt it.
Yes you can buddy. Download es file explore first. You can install it from google playstore. After that open your es file find the folder of emerald make a copy if it then paste it to pokemon theta x emerald folder
When I patch it it says: The Patch Doesnt match the file
can u tell me how to fix the saving bug?
when fighting E4, i usually lost my save file, and back then i can fix by save before meet the champion, but now i cant continue the game
The ear isnโt working for me itโs not piping up on John gba lite
Where do I play this game because in my app My boy I canโt open this game so where do I play this game
?????
This is a patch file of Pokemon Theta Emerald Ex, patch this file to an Emerald rom to play the game.
Hello, may I ask if what are the difference between your 2017 version in this new version? Bcoz I want to play this again if there are major changes
Hi Jazz, what do you mean? Because this 2017 version is so far the most recent update of this game.
After I achieved 6 badge I got Mega armlet from ash mom and then I bought a sceptilite and allow my sceptile to hold it then it doesnโt mega evolve continuously for 1 hr. Why ???
try a new emulator
Are there any glitches in this game?
Hi there Powerstaark, glitches are common to rom hacks, expect it to happen in this game. But glitches canโt prevent you from enjoying, so go ahead and play it.
Do you know what the glitches are so people can be prepared for them?
It ruined the joy when all my hms and tms were gone after the battle tend freezeโฆ And there is no proper working or good instructions for hm/tm cheat in the web, iโve been searching for 2 days. Can you tell me how to engage it???
Yes, if you talk to a girl that makes your pokemon lear hydropulse tour game will crash
I am pokemon fan
Good to know that pal, and we are all a Pokemon fan here :)
how to patch it ?
I have used this rom for a long time now, and recently I discovered that the last pokemon in my party seems to be corrupted. It has a ? before its hp and the level has grown to 63. (this used to be a low level pidgey.) When used in a winning battle, when gaining exp points, the game would freeze. I tried putting the infected pokemon in the pc, and there were several lines going through it. Iโve deleted the rom and restarted and I keep having this problem, even to the point to the pokemon disappearing in the pc box. Does anyone else experience this problem or know how to fix it? im desperate
Can this game be randomized? If so, how do I go about doing so?
How to get reshiram cause i cant find it in sky pillar. Please help.โบ
Go to route 131 and search that area
which of the gba pokemon hacks lets you choose from 1 of 24 pokemon? someone I know told me about the game, but I forgot the name of the game. if someoneโd help me out, iโd appreciate it.
pokemon dark flame
Which emulator is to use
Use MyBoy or John GBA, this works for many of our readers.
Can you please teach me how to play this game? I cannot patch it, I already try to patch it but after i patch it the game freezes
i found a bug/glitch where talonflameโs move change after i use the original move ,
i was on victory road and was doing some double battles (where it glitches very often) and when i used the move โbrave birdโ with talonflame and shifted my other pokemon at the same turn the โbrave birdโ turned into โheat waveโ , even though i didnโt have โheat waveโ . just throwing this bug/glitch out here to hope it does something :3
edit : it softlocks very often in double battles
It would be best if you donโt defeat the other pokemon in double battle focus on 1 lane as they say
Hey man. The game is nice but i experience a glitch and i need your help. All my items are like this: potion x?09 and my tm and hm are all gone. Experienced it when i beat watson. The prob is my game is saved. Any solution here? Can you answer it? Thank you.
Oh, did you use the all item or all Pokeball cheat? Try to avoid using those codes, and thatโs the reason why you canโt find those codes in Pokemoncoders. Check our page Pokemon Theta Emerald EX cheats.
I used the following:
Wild pokemon modifier
Rare candy cheat
Infinite money cheat
Then after i picked up heart scale, my items went x?09 and tm/hm are gone.
Sorry to hear that Plasma, as a rule of thumb make sure to turn off unneeded cheats. Also, just to be safe save progress before using any cheats.
Thanks man. Maybe a few fix is needed. Iโm rating the game 9.5 out of 10.
so, like, is there a new story or is this just pokemon emerald with new pokemon?
It has new story with new Pokemon. Most rom hacks has completely new story.
Completed Full Game
pokemon red chapter bulbasaur is not evoling in16 and it is now 20
Love this game so much!
also THANKS FOR THE CHEATS
REALLY APPRECIATE THEM!!
Thanks for dropping your comments shunreiDxD and Iโm so much glad to know you liked the game.
When I try to patch it using my boy , it says this patch is not for this rom.I renamed the .ups and .gba with the same name not changing the .ups and .gba ,it still says this patch is not for this rom,pleased can you pre patch it?
If youโre having hard time patching this game to your emerald rom then I suggest just finding the pre-patched download for this game. Sorry Glazz but I donโt share such kind of file as Iโm not allowed to do it and itโs not legal to share those files. I suggest checking other websites for pre-patched roms.
Can you tell me the name of those websites or can you give me a download link for a prepatched file?
Actually, with a simple google search of this rom hack will reveal those sites.
Thanx
Yeah no problem, itโs always been my pleasure to help my fellow Pokemon fans.
Yes your rigth
Downloaded this Rom, I couldnโt find it in my boy. Tried to patch this Rom in an emerald rom and due to it being zipped I couldnโt, I unzipped the emerald Rom and I still couldnโt patch it. Anyone can help me how to play this Rom?
Are all move animations included in this game, like greninjaโs water star/shuriken attack? All the previous versions had missing move animations for certain moves. I want someone to verify if this is fixed for this version before I download.
This is the most current version of Theta Emerald EX, so I guess the feature youโre talking about are in this game already.
does dragon ascent and draco meteor in this game?
I canโt join in the pokรจmon contest it always hang in the part where im going to make an appeal please fix and i removed all the cheats but still hangs
some hero get the patched roms in *.gba file???
thanxs! :)
Its possible get Purrloin with Prankster?
yow, just found out about this hack and how do i patch this properly? i do have a clean emerald gba file, and i followed the steps properly on patching it with nups (itโs not my first time patching with it anyway)
Since youโre using NUPS to patch this game, trying checking the โignoreโ in the โIf patch is invalidโ section and the game will work smoothly I believe. Let me know how this fix goes to you.
well it kinda just got a black screen on the patched game, been looking if anyone had the same problem as me but no luck so far
I see, in that case I would suggest just find a pre-patched ROM for this game.
Best Tom hack I have ever experiencedโฆ But the game is full of bugs and glitchesโฆ It could be more funโฆ
Thereโs a newer version of the game called Pokรฉmon Theta Emerald Renev have you tried checking it?
just found out about this hack and: how do i patch this??? keeps saying i have the wrong file even though i made sure itโs a clean one
This is the latest version of the game????
Yes this is the latest version of the game.
Everytime i send out pokemon or a wild pokemon appeared my screen have a green thing that flowting on the Pokรฉmon snd then gone just like that fix that please
Make it sure to disable those unused cheats. Glitch, freezing and sudden resets happens when the game gets crazy because of having too many cheats enabled at once.
This doesnโt seem to work with My Boyโs autopatching. Following the rename instructions will only result in starting Emerald, not Theta Emerald EX, as if My Boy canโt work with this patch. Very odd.
Happened to me as well so Iโd just patched the rom in my computer.
Completed?
Mulitpatch, for Mac, is not able to patch the game successfully, and the NUPS patching tool bundled with the game is not compatible with Mac.
Please add a Read Me / instructions for how Mac users can patch the game with this hack, as it does not appear to be a standard format..
Try patching the rom hack on Windows computer or use another Emerald rom. Alternatively, just search for a pre-patched version of this game.
I canโt find emerald version for this game
