  1. 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 only have normal type moves, you’re screwed. After finally reaching my first objective in the story, my Pokémon were already lvl 18. Then after I finally reach the person that needs help, after a couple lines of dialog, they teleport back and I have to walk a few miles back and get attacked by Pokémon about 47 times. Im trying to wait until the game gets fun, but man is it hard.

  2. 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.

  3. 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

  4. 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 for no reason.

    • 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.

  5. 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?

  6. 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 tho (I tried but I decided against it).

    So I fly back to the center and make all the way to the victory road only to notice that all the pokemon I see are shiny (all cheat codes disabled) and become bad eggs once captured I went to other places to check but every pokemons I catch are bad eggs so I guess the fly to the league whitout taking the proper path first corrupted my state.

  7. 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.

  8. 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 ?

  9. 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.

    • 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.

  10. 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.

    • 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.
