So I have an issue with the day and night cycle in my save game I have tried to restart the game and start a new game. But same issue,i cant tell when it’s day or night because it’s always dark but not night time dark it’s like a day time mixed with night and it’s constantly.

Hey I Tried playing it today and it said “The 1M sub-circuit board is not installed” any help?

So it keeps saying to enable the real time clock. I went into settings and enabled it and made sure it was check in the drop down menu. I’m using VisualBoy, but it keep saying i need to enable the Real Time Clock? How do i get it to work so i can have the day and night cycle?

The fact that togekiss can’t learn aura sphere, air slash, or flamethrower in this game is ridiculous.

Does it go by gen 3 rules for moves, in that fire is special and rock is physical or, is it based on moves, as in thunder punch is physical

Constant aleatory weather changes on every route and trainers healing up to 2-3 times per battle make this hack rom obnoxious. The whole idea of it is intriguing, but as far I can see, numerous people are experiencing glitches and founding problems here and there. Such a shame the creators ceased the development of this rom, because as I sad earlier, the concept is great.

They didn’t ceased it, their facebook page got taken down but their active on discord, I saw them looking for beta testers few days ago.

Hi, I have been playing the game for a while now and I would say it’s pretty solid. Yeah, there are bugs here and their, but fuck that! It’s an excellent mod nonetheless. By the way, does this ROM hack features later generation moves like Brave BIrd or Dragon Ascent?

Do I have patch this with a Fire Red 1.0 Rom?
I ask, because I started the file on my MyBoy emulator after downloading it and it runs.

Hey is this really the bug fix about the ghost in cerulean city..need you answer cus I recently download it and I haven’t try yo play yet..make sure I’m not gonna waste my time again due to the bug in cerulean city.

I don’t know but the second effect of Mega-Pinsir still doesn’t work.
Normal type move doesn’t turn into Flying type move after mega evolving! I still don’t hear the sound of “super effective” when hitting a bug type pokemon. It’s frustating! 🙁

Is there a way to evolve aipom to ambipom? How to make aipom learn double hit?

Hello, i´ve started shiny gold some days ago and upon completing the elite 4 it plays the credits and completely resets the game, is there something i can do to fix it?

I got the exact same problem, changed save file to 128k and restarted game but same issue

How can I use my 1.3.6 sav file in the new version? I tried renaming it but nothing is working? it kept on saying cannot load save game for POKEMON FIREAXE

I’ve been stuck in the Mahogany gym cause the switch doesn’t spawn the stairs for me to go to the next room. Just saw the new version updated that bug. Thank you very much.

Does someone know what happened to the rom’s facebook page?
It suddenly disappeared and now there’s no way to check on the progress of the rom.

Does anyone know where you can catch a scyther early on in the game?

I think in the park above goldenrod city, last time I grinded I think I encountered a few

Just started playing this hack today (v1.3.8) and found a soft lock. When you wipe out before reaching Cherrygrove City, you get send “back” to the PokeCenter in Viola City. Trying to go to other places in the town are getting denied with message that you need to go to professor Elm. You can also pick up the mystery egg from professor Oak and trigger the rival fight as well as the fight with the lorekeeper. But you can’t show the egg to Elm to progress the story or talk to your mother to get the amulet coin or the… Read more »

Hi! I was wondering if anyone was aware of any increase in the number of boxes in the pc? I have not updated from the previous patch just yet, but I know a few newer games have a larger number of boxes to allow for completion of the pokedex and the various forms of pokemon. Thanks!

Im having kind of a problem, after the bellsprout tower and after beating the 1st Gym when i walk down the road to go towards azalea town theres a guy that keeps saying “you gotta beat the gym first” i beated the damn gym, why this dude wont let me pass?

I’m having this problem, too! I can’t find where the assistant is to give you the egg, wondered if this was the cause? Thought he was supposed to be in the pokemon center.

you are supposed to get an item from one of the professors assistants, he is located in the towns pokemart, after the gym fight you get a message.

Should I supposed to Lose in Indigo plateau: -johto saga? To play the Kanto region?

Should I suppose to lose in Indigo plateau – johto saga? To play in the Kanto region?

Where can I find suicune? i did it in ciawood tho

From the official walkthrough guide: “About legendary dogs, Suicune is
at Tin Tower, Raikou at Mt. Mortar and Entei down
Blackthorn, random all of them.”

I found Suicune right at the entrance of Tin Tower.

Do you have to patch the file to fire Red or just play?

Can anyone recommend me patched pokemon roms website? I suck at patching

I might have found a bug…sometimes my machop using fighting attacks against normal type pokemons such as sentret doesnt have a supper effect…reply if i am wrong please.(this was discovered in the third gym of the first map)

I love the game. My problem is, when I cheat shiny mons on, it won’t evolve, it just say “?”. I keep evolving it but nothing is happening, is there any solution that can fix it?

Hmm… I recall we had a similar issue two other people described something like this in the other comment section on the Cheats page.
I could reconstruct this kind of scenario, when I tried to evolve or caught Pokemon before i got the Pokedex. Have you done one of that?
And could you please give us further information on what cheats you used?

I’m not able to pass the blackthorn gym the police is blocking the way. Although i completed goldenrod team rocket task but stiil can’t go through the gym. Please help me

this game looks good but I’m trying to find a game where I can set my character on a route and let him walk around and battle for me while I’m working. Does anyone know if there is a pokemon game like this? if you do it would be supper helpful!!!!

Dang,its updated glad i checked

Where do I put the cheats in ?

In your Emulator should be a Cheat Option in the Menu. Using MyBoy is the following: Open Emulator -> start your Game -> when in Game, open Emulator Menu (Square Button with three horizontal Lines in the Middle between L and R Button) -> click on Cheats -> add new Cheat (Plus Sign in top right Corner) -> enter Codes, name it and save it -> close Menu by clicking back Button (in my Case sometimes need to hit it twice or three times?) on your Phone to go back into Game -> check if Cheat is working. p.s. if… Read more »

have you already fixed most of the hidden abilities that does not work just like the moxie and refrigerate?

so is this game worth playing? or too many bugs

I used to be excited about it but for me at this point it’s unplayable. I’ve uninstalled and reinstalled a few times and i am still getting this bug where my pokemon are not listening to me even though I have a gym badge and my level isn’t too high. So this is really frustrating and Idk about you but for me it’s just not worth it.

I would love to play this game again, it was fantastic to have access to every gen at once, but is the bad egg glitch fixed or is there a way to get around it? It made the game totally unplayable. I tried multiple playthroughs, every time making it about halfway through the game, when bad eggs started appearing, specifically in box 6. So many hours down the drain! Has this been resolved?

Is there a Cheat Code thats has MAX EV ( NOT IV )

I keep getting “the 1 mil sub-circuit board is not installed” how would I fix this?

are there shinys?

Yes there is.

Is it finished?

Thanks, also are you able to go to Hoenn?

My Pokémon are not evolving?

Thanks, also can you go to Hoenn? Also, is it a 1 to 1 Gold remake (Aside from Orange Islands and Hoenn)?

theres zinnia
( from oras ) and theres an item called the link cable that evolves trade evolution pokemon and u get 10 of them in the beginning of the game inside the pc

Is leaf blade special attack or attack?
