This game is the worst when I played it all my data was gone

The game crashes when i mega evolve

How can i get lycanrock dusk form? Sorry if its obvious i have been trying for awhile.

Is this game completed ? Or is it still being updated?

Hello Guys, First of all, I would like to thank everyone who worked on this masterpeice (Pokemon Ultra Shiny Gold Sigma v 1.3.7) I am really enjoying the game, but actually I am facing some issues such as: 1. The poke fluet is not working on snorlax 2. I can’t recieve some items as it says the bag is full while it is not 3. Most of the legendry pokemons apear again and again 4. I defeated all the 4 orange island leaders but yet can’t access the last one 5. Can’t find a way to break the large rocks… Read more »

if u used cheats then it may be due to cheats
but we know that it is a new game so it surely contains glitches

Hi can sceptile mega evolve and typhlosion too????

Does this have the Primal Reversion feature?

Update: Sorry for asking, I didn’t do enough personal research. To those of you bothered enough to have the same question I had, then the answer is Yes. There are Primal mechanics of some form.

Where do i get the radio visio?

Hello! I’d of course like to thank the creators for their hard work on this game. I’ve put about 35 hours into this game so far and I’m genuinely loving it. I’ve never played a pokemon game where I’ve cycled so many different pokemon through my team as I’ve just enjoyed training and exploring the games content. I’ve seen several comments suggesting that this game is still being worked on, which I hope is still true. If so I was wondering if there were any rumors about adding additional boxes to the pc? I know that there is a way… Read more »


is this a competed romhack now from start to finish yet


Can someone answer me please if ghost attacks are stil physical attacks like in fire red or if they rightfully changed it to special attacks?!?!?!?!?!

the game has Physical and Special split i believe , so yeah , attacks can be physical or special regardless of types like in Gen 4-8

How to evolve Salandit? I has a female one and it was supposed to evolve on level 33, but it is on level 34 and hasn’t evolved.

I can’t Surf. I have the badge from Morty but I literally can’t progress because I can’t Surf anywhere. When I try, it says a new badge is needed but I can’t get anymore badges!


Does anybody know if there is a Nature Modifier cheat like in Pokemon Emerald???

Not a cheat but you can buy a capsule for 8.500 Pdollars in Mahogany Town I think, that enables you to change the nature

The 3 tiles around the interior door in Celadon City pokemon center, along with the two tiles (vertical) as you leave the city to the west, writes data to the 12th slot in box 6 (last slot in row 2). If there’s a pokemon there, it becomes a bad egg; if the spot is blank, it becomes an invisible bugged pokemon that you can just release

To be more specific, it writes 0129 012A 0000 010A 0154 at 0x02FEC5A8 (around there, the box slots seem to move around)

Not Celadon, Cerulean
Although maybe Celadon too, I haven’t checked

I was trying to figure out what causes this. I randomly get invisible bad eggs in box 6 but I only have one badge and it happens every time I add a phone number in game or even when receiving calls on the Pokebeeper. Also, if I release the bad egg, it also deletes the phone number I added.

Interesting that walking on a tile can cause one of these too.

what is miracle exchange?

Dark cave has some collision issues. I was walking through a few walls.

The typing system is all messed up. For some reason my ralts is weak against poison when poison should do little to nothing against psychic. Is there a patch that I need for this or is just the programming?

ralts is part fairy as gen 6 and fairy types are weak to poison

Ralts is a fairy type now, which is weak to poison. Psychic has no resistances to poison, and steel is the only type immune to psychic.

ralts is half fairy, its gen7 rules

hey can you reupload guide file because the file not found thanks

The stair case in ice gym is not visible… I cannot progress to fight with the gym leader… What should i do… Plz help… Thankyou

Where is the 7th gym in Kanto? I’m stuck.

Cinnabar Island.

Surf from Pallet Town

Had the same issue, Just walk up and down over the button more than once that fixed it for me.

This i s the worst rom hack ever this doesnt even have the same teams or levels

Are developers going to fix pokemon cries?
Its kinda annoying hearing bulbasaur’s cry every time lol


Hi, amazing hack rom
Is it possible to play with other players?
I mean using My boy link remote with wifi or bluetooth.
Thanks for your answers.

Has this updated version removed the bad eggs? I have tried to play through twice on VBA link, and both times there have been invisible releasable bad eggs in the sixth box on the PC. Worse still, pokemon started turning into bad eggs both times shortly after reaching kanto, rendering it unplayable.

did you already removed the eggs?

is this newer than regular shiny gold stigma and if it is what is the difference

Does it have melmetal?

I’m trying to battle Clair but the boulder is stuck I tried both different holes and still lands in the same spot? What to do

I can’t acces tge start-menu. It just stops the rom and closed it. Can’t play the rom though.

This was happening to me also, try a different emulator.

Why skorupi and some pokemon not exist in pokedex

Hey folks, I played this beautiful hack for a couple days now and i’m amazed like never before from any other Pokemon hack. Big thanks and probs to the developer and host of this page, great work so far you helped me a lot! Unfortunatly an issue occured after beating the Johto top four + Champ (Lanze) first time. Somehow the game doesn’t save my progress. So after the credits the game forces me to Start a new game… Meaning I’m not able to progress the story (Kanto Region, Orange Islands, etc…). I tried to fix the issue by setting… Read more »


Friend im sorry to say,you need to setup save type to 128k before starting a new game. You will have to start over.

Hi I’m trying to play it on my Nintendo DS, but I can’t save or even set the clock
Do you know what I could do?
I am running the homebrew on the 11.9 version and I converted the gba rom into a cia rom and then I installed it on my DS

You have a 3DS or 2DS, NOT a regular DS, but that’s not the problem. Try playing the game in an emulator or using a flashcart. Hope this helps ☺

Where can I get a mega bracelet, or is there any cheat code

is this is for android?

hey I’ve been playing for a while and everything was alright until I won the fourth badge, then all of my TM were gone, only the HM are still there. Even when I buy a TM and look for it in the case it’s not there. What’s the problem? Any way to get it back?

Is this the unfinished version? I find it a little different with the one that people play in YouTube, plus there are still some places that unaccessible

Quick q: In goldenrod I bought enough coins in the game corner to be able to get a riolu, I got it and it was a shiny one and after that every Pokemon I encountered (wild and in battles) was a shiny. Is this supposed to happen? I mean all the trainers in the route after goldenrod(the sudowoodo that blocks the path) has a shiny…is that like part of the game?
