  5. reporting a bug, will do on discord also.

    Left my lvl6 Onyx (m) and lvl10 -geodude [alolan] (f) at the day care centre before defeating whitney. defeated whitney, went back and there was an egg (yay), retrieved the egg and then day care lady told me that both mons had grown by ten levels. in the retrieval menu onyx said lvl 16 and -geodude said lvl20, retrieved both at once for 1100 poke each, once they were in my party both pokemon are at lvl 0 with lvl 0 stats and all moves have been forgotten except their lvl 0 moves.
    playing 1.5.0 on MGBA on windows, this is the first bug ive encountered. Thank you and hope this helps somehow

    • Update on my bug report, It wasnโ€™t the rom, It was the Lua script Iโ€™m using.
      I am having a real bug however, Elm wonโ€™t give me the Master ball, and Whenever I lose at the Pokemon League, the game doesnโ€™t bring me back to the Pokemon center at the league, It brings me back to the one in Veriteon City, witch is the one I used before the one at the Leage, because I was too lazy to go back through Route 27

    • Another bug report, when waking up, the glitch string โ€œร  ร™ร โ€ is a briefly visible. Glitch strings like these are usually unintended consequences of glitches, but I havenโ€™t even done anything yet!

    • The game doesnโ€™t have a patch file version available for download. Thatโ€™s why I decided to remove the download button, I suggest checking out the source link and going to their Facebook page for more information.

  11. 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 itโ€™s day or night because itโ€™s always dark but not night time dark itโ€™s like a day time mixed with night and itโ€™s constantly. I can sometimes tell when it changes but I think itโ€™s just a lighting issue because when I walk into a building it flashes back to the normal day or night for a second,then when I come back out itโ€™s the same thing really good game and Iโ€™m still gonna play just wish there was a patch or something

  13. 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

    Reply
  14. 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.

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

  16. 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.

  21. Does someone know what happened to the romโ€™s facebook page?

  22. 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 โ€œbackโ€ 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 canโ€™t show the egg to Elm to progress the story or talk to your mother to get the amulet coin or the sprint shoes. Additionally items were spawned in locations that normally doesnโ€™t have items. The reason the story canโ€™t progress is (I believe) that you already have visited Viola City, so the game thinks you already got the items from you mother as well as showed the egg to Elm (hence why they donโ€™t trigger their respective events). This also effects the two battling trainers on the road above Cerrygrove City, who are blocking your path. They donโ€™t disappear because you never showed the egg to Elm. In regards to the random item spwans, I think the game got confused on what scripts to load and loaded some other data as scripts causing the items to spawn.

  23. 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!

    • Hmmโ€ฆ 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?

    • 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 a Cheat Code is longer and needs several Code Lines, simply enter each Code Line as a new Cheat and activate all of them together

    • I used to be excited about it but for me at this point itโ€™s unplayable. Iโ€™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 isnโ€™t too high. So this is really frustrating and Idk about you but for me itโ€™s just not worth it.

  29. 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?

  30. 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 canโ€™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 canโ€™t access the last one
    5. Canโ€™t find a way to break the large rocks thay blocks some doors
    6. Team aqua is waiting in the cycling area but yet I canโ€™t swim and dive

    And so on with the issues,โ€ฆ.

    Can you please explain why I am facing this issue?

    Best regards

    • Hello! Iโ€™d of course like to thank the creators for their hard work on this game. Iโ€™ve put about 35 hours into this game so far and Iโ€™m genuinely loving it. Iโ€™ve never played a pokemon game where Iโ€™ve cycled so many different pokemon through my team as Iโ€™ve just enjoyed training and exploring the games content. Iโ€™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 to update the mechanic to 25 boxes as Iโ€™ve seen it in a few newer rom hacks. I donโ€™t however know how much work it requires of the creators to fit it into the content of their game. Thank you again and I will continue to enjoy your game.

  34. 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 thereโ€™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)

    Reply
    • 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.

  39. Hey folks, I played this beautiful hack for a couple days now and iโ€™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 doesnโ€™t save my progress. So after the credits the game forces me to Start a new gameโ€ฆ Meaning Iโ€™m not able to progress the story (Kanto Region, Orange Islands, etcโ€ฆ).
    I tried to fix the issue by setting the 128k save mode on my VBA emulator v1.8.0, but it was not solved by doing so.
    I think that I donโ€™t have to mention how frustrating it is. Would be nice if someone can help me with this.
