Is there exp share to all pokemon?
no
This game sucks and is so poorly made. I must’ve fought at least 25 trainers before any storyline dialog with any npc. You are forced to walk through so much grass and cave and with limited money, you can only afford so much potions and repels so you have to constantly run back and forth to and from the Pokémon center. This is all while trying to get to your first objective. Also for some reason they think it’s a good idea to throw a bunch of ghost type Pokémon at you so if you are out of PP and… Read more »
Whenever I press start in the battle, to mega evolve, (similar to theta emerald) the game freezes. I do have the mega stone, just got it from fixing the lab.
I think there is a bug in your game because wen I went to the lande region it was fine from the start but when I used fly and pressed the lande region in the map my character landed on a foggy location and I don’t know how to get out of it.Thank you
Its not there game they are just sharing the creators ROM hack on their website
by the way i made a comment asking about a fog screen problem i just want to point out its version 5.59.
So not sure if it’s a bug or not but when I use either dive or fly mainly fly going to the land region. The red box. Everything becomes a massive fog that doesn’t let me see anything. I’m 100% blind on all dive areas and the map when flying to the red box on the land region. If it’s a bug how do I fix it and if I need an item can someone tell me what item it is and where to get it. Bugging the hell out of me, and it makes it very hard to fly… Read more »
Thanks for coming here Molten, I believe it is a bug on the game that you currently experienced. Sadly the game hadn’t updated for several years, and it’s quite disappointing.
I only used to play flora sky and lesf green,the basic version ikk but i want. to play this then i see comments about patching patching,,anybody that can explain that to me?idk what does it mean.Can i play this without the whole patching thing?
Having trouble at patching it, any tips?
-Thanks
As far as I know, the game requires V1.0 Emerald rom for patching.
Do u have any randomizers
What emulator can I play beside MyBoy? I’m using an Android phone.
You can use John GBA
What kind of emulator can I use to play this rom hack?
MyBoy for Android or VBA for Windows works well for this game and majority of rom hacks.
Thanks. Much appreciated.
I still can’t play it in MyBoy , it says that “Unrecognized GBA file”. What should I do? I appreciate it if you can help me
I noticed an odd bug I don’t know if it is known but I’m about to beat the Ivara league so after getting my last badge I decided to fly to the league but I didn’t notice there were 2 points avaible at Ivarra: the pokemon center and the league itself so I ended at the league right away where I made a save state. At first I tought it was planned to be possible since it’s a hack but when I try to speak to Amalia the screen freezes and the music keeps going I can challenge the league… Read more »
Now some pokemons shiny spawn in the victory road and all are bad eggs (cheat still disabled)
I think restarting your emulator can help.
I did multiple times and the bug persisted until it stopped after many resets XD. So indeed restarting helped me thank you !
No problem Helysiel. A simple restart can fix majority of problems. Thanks for coming here and happy new year.
Thanks for your feed back on this Helysiel, hopefully the team behind Mega Power will fix these issues you mentioned.
Hi, I’m trying to get an emerald based Rom hack but I can’t find any. Could you send me a link? I’ve already downloaded Multipatch and the Mega Power UPS file.
Hey there Josh, but how about your Emerald version? I believe you need to patch this with V1.0 Emerald (US) rom. Sorry but we don’t share information about rom files.
Hi great hack thank you!
that said the pokemon cries are bugged (Togepi’s cries on Hoopa and so on) will there be a fix for this ?
Hi there Helysiel, thanks for coming here. Unfortunately we have no update as of yet for this game but I’m glad you liked it.
ayo how do i patch this to my emerald rom, im kinda new to this whole emulator rom stuff so if i could get a simple explanation that would be appreciated.
Hey there, we have created this guide on How To Apply IPS Or UPS Patch to Play a ROM Hack, also we created this video guide https://www.youtube.com/watch?v=9ch5EPf8z80 check them and hope they all work for you.
I have both a FireRed and Emerald ROM but it still does not work. I am Using MyBoy! Advanced
Thanks it working but can I know all mega evolution list for this Pokemon mega Power.
Can I evolve pokemon by level up that normally evolve by trading?
Hey
can you guys send me the pre patch version of this romhack please
because i can’t patch this romhack at all
thanks
We don’t do it here pal, sorry to disappoint you.
What do i do when the game doesn’t work i tried many times but it doesn’t work!!.
You can’t play the game directly to your emulator. You need to patch the downloaded file in your Pokemon Emerald rom.
Just put them Patched, why would you not? Makes no sense at all. Glad that i actually found a PATCHED version.
No mate, sharing pre-patched roms is piracy and clearly illegal, I know some sites are doing this but not here at Pokemoncoders.
Teach me how plz
How do you get it to work on the android my boy emulator I tried to patch it and even that didn’t work
Does this have P/Sp Atk Split?

.
Can anyone say how to find Hoopa in mega power beta 5.59
Yo how tf can i play this game
you have to patch this game file to your pokemon emerald to get it to work, its essentially like an add on or a mod in a game.
Nice game, top of my list so far. But I hope the author fix the Pokemon Cries. Snover cries like zigzagoon, Abomasnow cries like a Tailow, etc. Hope it gets fixed though.
After defeating the first gym leader (Joel) how do I get to Klaus, I can’t use Cut without proper Gym Badge.
add the patched rom at download… cuz i cant patch the original rom… thanx :3
Sorry pal but I’m not allowed to do it.
Which version is compatible???
Which emerald version is compatible???
It says error when I patch it. Please help.
If you’re having trouble patching the file, then maybe your emerald rom is not compatible with this game. In that case, I would suggest looking for a prepatched version of this game from other sources.
Can you catch the mega Pokemon in this game?(spawn them in with cheats that is)
Yup, check the Mega Power Cheats for the list of available Mega Pokemon codes.
It doesn’t work for me and i did what the video said to do
Why does it no work in my my boy?
Use FireRed (U) Squirrels version to make it work.
how does one use fire red (U) squirrels version to make it work
Bro, this ROM hack will not work on FireRed Squirrels, this is an Emerald based ROM hack so you need Emerald ROM for this to work.
