i keep getting this error


Pure virtual function being called while application was running

LowLevelFatalError … WindowsPlatformMisc.cpp Line: 439

th e game is well made good work

game looks great and the artstyle is very polished but then i ran into 6 glitches all within 10 minutes of the game which caused me to restart eg once switching pokemon the game wouldnt show the ui so i couldnt battle this happended twice, when i was walking through a patch of grass every single tile of grass triggered a random encounter this happened four times. regardless of these issues i would really like to see this game become a full game

so the rayquaza load screen came up and instead of MY 6 pokemon it was 6 gardevoir lol and my save file is replaced by a file named Brendan which shows 6 treeko in their party and the other stats of brendan. when i try proceeding with that file i get errored "Pure virtual function being called while application was running (GIsRunning == 1)."  with a LowLevelFatalError u5 error. im trying to upload the screens im talking about but this site keeps asking for "verification" when i try. oh well.

just downloaded the game but I can´t play a new game. I always get this error. 

LowLevelFatalError [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Core\Private\Windows\WindowsPlatformMisc.cpp] [Line: 439] 

Is there a troubleshooting thread somewhere or do you guys have a solution for me ?

Is there a wiki for this mod? or something? I noticed mudkip learned aqua jet and the moveset isnt matching with what im use to. Do please tell me I need to research this ;-;

The game looks incredible and makes a lot of fun so far. the only bad thing is, that it keeps on crashing. I am excited to see how it will look like in the future

Title: Soft-lock after Dragonite fight in Blooming Forest (player falls endlessly through map)

Version: Latest demo on itch.io (downloaded October 28 2025)

Platform: Windows 11 

GPU/CPU: AMD Radeon(TM) Vega 8 Graphics 

Ryzen 5 3500u with radeon vega mobile

Steps to reproduce

1. Play normally and travel through the blooming forest after beating mercenary leader of team magma.

2. Start the Dragonite encounter event.

3. Whether I win, lose, or catch the Dragonite, the post-battle cutscene fades out and my character immediately begins falling through an empty void.

4. Reloading the save (auto- or manual) always spawns me mid-fall, so I can’t recover or move.

What I expected:

After the battle, the player should reappear on the ground in Blooming Forest or trigger a post-battle cutscene.

What actually happens:

The player loads below the map’s collision layer and falls endlessly. The autosave overwrites the file, making the save unrecoverable.

What I’ve already tried:

• Restarted the game, re-launched, and limited FPS to 60 using the pokemon emerald>saved>config>windows>gameusersettings file

• Verified files, fresh reinstall, and restored backup saves

• Same result every time

Save file:

I’ve backed up the broken save. It should load directly into the falling state right after the Dragonite battle.

Notes:

Other players on the itch.io page have mentioned similar fall-throughs. It seems tied to the Dragonite fight transition specifically. If you need my save to debug the coordinates or spawn trigger, I can provide it in dms/privately.

How do I get the game to stop crashing whenever I'm in the Ashen Forest Cant make it past there

Love what you’ve built!
I’m working on something similar — it’s called TWT Community, a tool that helps people easily create their own communities.
Would be great to explore a possible collaboration!

for anyone trying to run this on Linux: Steam -> Add non-Steam game -> Select the .exe -> Right click on game on the library -> Properties -> Compatibility -> Mark the box

I'm almost sure that this will run just fine on Proton Experimental, but I'm using Proton GE-latest. if you're not aware about how this works, take a look at ProtonPlus, it is really simple and avaiable on Flathub.

I'm not sure if you're reading these comments, but I figured I'd leave some feedback.

The game is stunning! The battle UI is perfect. However, I think if the camera angle was a bit more like the DS games, the sprites would look less distorted. You have some details like the trees that seem to be at a different angle than the rest of the world, as if they are about to fall forward. As beautiful as everything looks, I do think it's a bit too dark and yellow. 

I'm not sure what exactly causes it, but everything feels a little sluggish. The text, the walking and battle. It's almost like it's in slow motion with an input delay that doesn't feel very satisfying. I'm hoping some smaller details, like the proper HG/SS "dancing" idle animations for following Pokemon and footsteps sounds will be in the final version.

All in all, this is one of the best looking Pokémon fanmade game and I can't wait to see where it goes. 

Is there somewhere to heal in Mysterious Island? I'm completely out of PP and can't progress at all. I've made it to the ash forest but haven't found anywhere to heal and the store doesn't seem to have any PP restoring items.

Dude... wtf... how i never play this game before?

anyone else's game crashing all the time?

yeah me too, at the start of a new game every time.

For anyone experiencing crashes with the magma grunt fight. The fix is to not fight with your starting pokemon at all.

Hi do you mean your lead or starter as both still seem to be crashing at the triple fight

Can't get the game to run on my laptop, after opening the game before even leaving the warning screen I get an error saying there is not enough memory on my system. I'm on a laptop with 8GB RAM and 4GB VRAM. I can't find a solution but I'm hoping resource management is solved at some point soon.

SAME!!!!!! I cant even play, when i juast start the game it crash

will there be a download for mac?

is there more than just gen 3 Pokemon and if so, is golurk one of them

Im getting this error "LowLevelFatalError [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Core\Private\Windows\WindowsPlatformMisc.cpp] [Line: 439]". Anyone got solutions?

(+2)

I had the same issue, and I get it to work by forcing it to run on Direct X 11, add a shortcut to the desktop, right mouse click on it, properties, and on "destination" add one space and "-d3d11", hope it helps

I sincerely hope you are able to stay anonymous so the big N can't take you down

The potential for this is insane and I cant wait to see the end result :D

Man, i love you, im gonna tell my sons this is how god look's 🙏

Wonderful game, I’d just like to know if there’s any planned or estimated date for the full version.

(+1)

will you ever do the Linux or Mac version?

I'm almost sure you can run this on Linux with Bottles, just like most fan games, but I'm gonna run some tests here.

Game looks fantastic so had to give it a go, will list bugs as I go along to help you troubleshoot: 1# was at the very start where for me it showed 'whats yer name lad!' behind all the other text while the ship is crashing - 2# is walking right into wild grass always causing an encounter.

another thing I just found out scrapping a psyduck was after spam hitting reflect w/ beldum psyduck could no longer cause damage to me, landing hits but causing no HP loss - possibly not a glitch but in pokemon games a landed pokemon move that inflicts dmg should always cause atleast 1HP los

4# - getting stuck on party pokemon I let out after a wild pokemon encounter, easy enough to put back into pokeball to get around this but something you might want to look a

5# - small hills that we shouldn't be able to walk over, I walked right over it but then turned around to try and go the other way instead - coming back now I can't walk over it so i'm sure we're not supposed to be able to - however I am now stuck with making progress as walking into wild grass from the right always causes an encounter (without steps being taken forward)

Overall - few small glitches here and there that just need to be patched but the game looks really good and I really like the fighting animations - also never played a pokemon game that felt so smooth (accidentally forgot favourable moves when leveling up due to fast input times) - I enjoyed playing for now!

Hello, I really liked this game and I think your work is incredible. It's admirable that we finally have a good game with the classic aesthetic. However, my curiosity wins and I would like to ask if we will have mega evolutions or any mechanics from the last generations. I think that since the game is set on a different island, these concepts could be added quite well. Thank you for your wonderful work.

Bugs so far: 

  • When switching Pokémon, the keys won't work until I hover over the buttons with the mouse. Or vice versa. 
  • Downed enemy Pokémon stay on screen. I was fighting a magma grunt with two mightyena. but the first one would not go away. I killed his mightyena like 7 times before it finally died. (Although it was a good way to farm XP)
  • The move Lava Plume will sometimes crash the game. 
  • If I go into battle with Pokémon following me, when I return, my Pokémon is directly on top of the player sprite. Cannot move until I return it to its ball.

Amazing work on game — it’s looking really good!

I just noticed one small thing: when the player walks to the right into grass, it always triggers an encounter

(-1)

I don`t know what I did, but solve - save, change first pokemon ... -, before, the character can`t walk, because walking to right just trigger an encounter.

Amazing game like truly the best pokemon game! The graphics are just the best! Here are the glitches that I faced from playing this game from the month of May and October:
- PP of some moves did not go down after using them, essentially making them able to be used infinitely (my quick attack, absorb, and pound all had this issue until i restarted the game)
- The settings menu would never save my settings
- Sometimes in battle, the game would start to glitch out where none of the buttons would work (had to hard reset to fix it)

- Checking the pokemons summary would do the same thing as the problem stated above (glitch out and not be able to exit that screen, pokemon would be sent out infinitely, buttons won't work, etc.)
- The mailbox shaped like a delibird at the beginning of the game also presented the issue where I could not exit it/none of the buttons worked after using the mailbox
- When I fainted, it reset all my pokemon to their starting level and reset the game almost to the very beginning

Hope these comments find you and hope they help! This game is going to be the biggest thing in recent Pokemon video game history so I am looking forward to the progress!

Hello, I wanted to report a bug crash that is happening to me, is giving error when entering the game when gives new game, the following error is this "Fatal error: WindowsPlatformMisc.cpp] [Line: 439]  Pure virtual function being called" what can I do to fix?

(+1)

WONDERFUL GAME!!!!!

So just some quality of life adjustments  that I noticed probably need to be fixed sooner rather than later:

-When a move is being learned, please add its name to every dialogue screen. Because if the player misses where it says what move it is the 1st time it's mentioned, they won't get a mention of what move it is again until after it's learned. It's a bit frustrating.

-The spawn rate of Pokemon in the grass is through the roof right now. I got stuck in a clump of grass endlessly getting into battles with wurmple until I reset the game multiple times.

-The music in world on the map is much lower than the music in battle. I have to constantly adjust the volume on my computer.

-Is it by design that we get money every time we defeat a wild pokemon vs a trainer? I didn't realize pokemon carried cash and that we shook them down for it and rummaged through their pockets every time we knocked them out! Not that I'm complaining, but it's an amusing idea.

-SOMETIMES, things are on top of each other, like in the image I attached. This goes for text as well as images. 


THANKS! WONDERFUL WORK!

Also also, the "restore" button in the Pokemon menu doesn't do anything. You can only heal pokemon from the bag menu. 

Also, when the move "bounce" is used, the Pokemon using it yeets itself into outer space, never to be seen again, and the battle freezes.

Also, I just had my Ludicolo, that I just evolved from a Lombre using a water stone, evolve from and into something invisible during the evolution screen and nowit looks like this in my pokemon menu...

(+1)

This is what it looks like when I swap it to slot 1.

And when i go to battle with it, there is nothing on the screen..

It's not there at all when I go into the pc. (Also, can you fix Combusken's head? He looks like he's too short for this ride lol)

And actually... now that I went into and back out of my pc, the "button text" treeko seems to be fixed by disappearing altogether. 

I'm out one Ludicolo oof..

STILL A GREAT GAME AND AMAZING THAT YOU GOT ALL OF THIS UP AND RUNNING!!

too much spawn rate ahah

Just Started playing and walked into tall grass and my walk along poke walked into the same space as me putting the mon away easily fixed it and some text during the opening stays on screen when new lines pop up nothing crazy but omg I would pour hundreds into this game keep up the good work mate

is there a way to donate or gift to the project?

best than all pokemon 3D a reel fan game

FOR EVERYONE WONDERING 

I saw a comment on the other website from where you can download the game how to launch it and start a new game without it crashing.

The different options were :

- Add it in Steam as a Non-steam game (also easier if you play with a controller thanks to Steam-input (from what I understood))

- Or if it shows "Fatal error: File:D:\build\++UE5\Sync\Engine\Source\Runtime\Core\Private\Windows\WindowsPlatformMisc.cpp] [Line: 439]", don't start the game that's named "PokemonEmerald.exe" when you first open the "windows" file. Instead, go to the file that says PokemonEmerald, Then go to binaries, then win64, Then you'll see "PokemonEmerald-Win64-Shipping.exe" in the win64. Run it as administrator and it should work! If it doesn't, relaunch it a few times and it'll work :)

And while you're playing : DON'T FORGET TO SAVE OFTEN, 'cause it's still a demo, and it crashes sometimes, and it doesn't save automatically

(+1)

FIRST I WOULD LIKE TO SAY I THINK ITS FANTASTIC KEEP UP THE GREAT WORK. THE GAME FREZZE MID BATTLE I BELIVE YOU SHOULD ADD A QUICK SAVE IN THE GAME SO WHEN IT DOES MESS UP OR STOP WORKING ITS SAVED TO THAT POINT IN THE GAME WITHOUT HAVING TO START OVER AND GRIND LEVELS AGAIN 

Unfortunately I’m unable to play because every time I hit ‘new game’ the game crashes and gives me ‘fatal error’ notifications. I hope this gets fixed soon, so excited to play! 

I posted a comment about how to make it work, if you're still wondering !

This is by far the best looking Pokemon fan game I've played. I do agree with the comment below that the option to lock the framerate would be nice as the GPU utilization on my 4070 ti Super is quite high. Otherwise, I patiently await more! This is really amazing work. I'm loving the original story so far and the free Beldum at the beginning is perfect. Metagross has always been one of my favorite Pokemon!
