trapped with the rocks 

I'm having trouble trying to play the game on Intel, as when i try booting the game up it always saying "Out of video memory trying to allocate a rendering resource." I try a lot of stuff to fix it but i couldn't fix the problem. Please is their anyone that can help me play the game without it kicking me for "Video memory"? I also use Window 11 pro and graphic card is "Intel(R) Core(TM) i5-8350U CPU @ 1.70GHz (1.90 GHz)

need to make the chanses of a pokemon encounter lower

only 7 i have been stuck in one patch for the last ten minute

if ur playing on a controller try changing to keyboard

I have been stuck in a patch of grass for like 7 battles now

I have been playing with a controller and it often happens that i get stuck in a patch of grass when trying to go to the right where it instantly triggers and encounter. I tried turning off the controller and playing with mouse and keyboard and now the encounter rate feels normal, (switching back to the controller the problem reapears). (if important its an xbox layout controller)

beldum was my first pokemon in a fight after visiting the "pokecenter" it got oneshoted and the game acted liek my whole team feinted and i fled even though my other pokemon didnt feint

my game keeps crashing when i use moves in battles in the ashen forest i feel like when its super effective moves but sometimes it feels like its random

https://vimeo.com/1141571957?fl=ip&fe=ec

bug i found :3, hoping i'm contributing to the game even for a slight 

I know its a demo but I have another bug in mind, sometimes the UX on the bottom right just disappears and gets me stuck. The situation was I was using beldum and I used astonish or one of his moves, then after that it didn't appear.

(1 edit)

For some reason the pokemon thats last in your party gets turned into a lvl 5 treecko called "BottomText" and just straight up deletes your pokemon.. Gone forever..

is there shinys ?

as soon as i start it, it crashes saying fatal error

I'm having 2 problems. 

First, I can't get the game moved over to my second monitor. Is there a different way in swapping it over to the monitor you want to play the game because in options/settings you are able to set fullscreen to windows and windows boarderless but nothing happens when switching through them and it doesn't save changes. Always on fullscreen mode. 

Secondly, I cannot get my controller to connect or work in game. Is there another way to get that to work or it should already work when plugged-in?

when i do the ichooseyou gift it shows the pikachu but then its not in my party or box. is there something i need to do?

it becomes a random encounter, its lvl 50 so good luck

Do you plan to make a macOS version?

Would love to try out the game but I keep on getting this error when trying to start a run

Hey! Good work here!

I just want to let you know the move "bounce" can brake the game. My Combusken just dissapeared on the air, but if i dont touch anything, the camera moves around and i can see my pokemon there just chilling XDD


Hope it helps to fix it! 


Have a good day and congrats for that amazing game!

This sounds like low level issue as The error shows. What Windows version are you using? Since this IS a low level crash we don't really know what IS happening behind The scenes.

i'm on Windows 10 family.

it every time a big attack is launch, right after it hit the game crash. 

it's the only time i crash, always when i use aqua jet or my Pokémon is touch by a big attack.

all my driver are updated and same as the OS.

Now that i am looking at The error, i see IT tries to reallocate memory but fails For some reason, giving unregonized block error

I thought the game was beautiful and when you match the ending with Love by you by Rebecca Sugar, it's absolute cinema 10/10 game can't wait for the full release


Fix bugs please

Crash in runnable thread Foreground Worker #1

Great game! But there are sone glitches that do need to be fixed. And I'd like to add Lebron the mudkip does need to be dulled down a bit because of the power system. But other than that it's a good game and hope that a full version will come out!!

A wonderful game though there are lots of little things to be polished up. Menus tend to stack on one another taking up the screen, though saving and restarting will fix this. pressing the A button quickly makes text and some other objects react multiple times like there is no buffer between inputs. I would also like to be able to switch around the order of a pokemon's moves.

Other than those and some other little things the art is amazing and the game seems to run well. I really enjoy it and can't wait for more updates. ^^

LowLevelFatal Error [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Core\Private\Windows\WindowsPlatformMisc.cpp] [Line: 439] Pure virtual function being called
This is the error code

Yeah same problem here:
Pure virtual function being called while application was running (GIsRunning == 1)

Same. I reinstalled it and checked my GPU driver was up-to-date, then it worked fine.

any fix? Been going at it for a few days now.

My Mudkip evolved, and then completely disappeared from my party. Not in the box or anything. I had to restart. Really sucks since I had caught a shiny Psyduck too and hadn't saved (rookie move, I know).

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?
