@BlackIce1824 I dug around in the save file, and had Claude AI look at it as well. It seems to be fine. I was able to import it with DeSmuME 0.9.13 and see the changes in your Chikorita's stats.

I would review how your emulator imports saves and try again.

For accessibility purposes, here is the text from the screenshot with Claude AI's recommendations:

Quote

The "game starts a new game" is an emulator workflow issue. The most likely causes:

  1. Emulator was still running when the save file was replaced — many emulators hold the save in memory and write it back on exit, overwriting the new file.
  2. Wrong file location — the emulator expects the save file alongside the ROM (same name as ROM), not wherever PKMDS exported it.
  3. Filename mismatch — the emulator may require exactly <ROM name>.sav, not the PKMDS-exported name.

  The fix for the user: close the emulator completely, then replace the .sav file, then reopen the emulator.

@BlackIce1824 The IVs have nothing to do with the save file not appearing to import correctly. Can you post your save file here so I can look into this? Or if you want to keep it anonymous, you can load your save in PKMDS and submit a bug report - there is an option to include the file when you submit.

PKMDS Update — March 18–25, 2026

New Features

• One-touch evolve — An Evolve button now appears in the Pokémon editor when the selected Pokémon can evolve. Single-path evolutions happen immediately; branching evolutions (Eevee, Slowpoke, etc.) open a picker showing each option with its sprite and method. Evolving Nincada into Ninjask will offer to place a Shedinja in your next empty box slot. Gen 2 trade evolutions now show which held item is required.

• Box pop-out dialogs — Two new buttons in the box navigation bar let you pop out the current box into its own dialog window, or open a full all-boxes grid view. The all-boxes view lets you swap adjacent boxes with a single button click.

• Generation-specific editor tab — A new “Gen-Specific” tab appears in the Pokémon editor when relevant, covering fields that only exist in certain games: Shadow Pokémon status and purification (Colosseum/XD), Shiny Leaves and walking mood (HGSS), PokéStar Studios fame (B2W2), GO Park spirit/mood and received timestamp (Let’s Go), and more.

• Pokédex: Legends Arceus research task editor — You can now open a per-species research task editor from the Pokédex tab in LA saves. Buttons to complete or clear all research for all species are also available.

• Spinda spot preview — The Pokémon editor now displays Spinda’s unique spot pattern based on its PID / EC.

• Trash bytes auto-fixer — Added a one-click trash bytes cleaner to the Legality tab for quickly resolving legality flags caused by leftover junk bytes in name fields.

• Origin mark shown in Met tab — The origin mark sprite (Pentagon, Clover, Galar mark, etc.) now also appears in the Met tab alongside the existing display in the Cosmetic tab.

Improvements

• Loading a .pk* or mystery gift file now places it into your currently selected slot (or the first empty slot if none is selected) and navigates you directly to the box view — no more hunting for where it landed.
• The Pokédex tab now has a filter to show only seen or only caught species, and the box selector dropdown shows the box count.
• The Bag tab renders noticeably faster on large saves thanks to grid virtualization.
• Bug reports submitted through the in-app report dialog now require a name and email address.

Bug Fixes

• Fixed bottom UI elements being cut off on iPad screens.
• Fixed several crash reports from Sentry (duplicate key crash, file-abort error noise, empty file load crash).
• Fixed held item autocomplete not being clearable; also prevents a crash when held item data is missing.
• Fixed pager visibility and filter button clipping in data grid views.

Hello all. Just wanted to let you know I've made some pretty great updates recently!

New Features

Encounter Database

• New "Encounter Database" tab — search for encounters by species and generate legal Pokémon directly into your save, with auto-slot selection.

Advanced Search

• New "Advanced Search" tab for filtering Pokémon across your save.

Pokédex Editor (major expansion)

• Bulk operations (Seen All / Caught All / Clear) for Gen 4–9, LA, and Legends: Z-A.
• Per-generation species panels with alternate form display tables (Gen 7, Gen 5/6).
• National Dex toggle.
• Legends: Arceus research panel.

PKHaX / Illegal Mode

• New HaX toggle unlocks illegal edits: uncapped battle stats, DEV_Ability (set any ability ID on Gen 4+).

High-Res Sprites (PokeAPI)

• Home sprites replace low-res images, with shiny variants and alternate forms
• Optional generation-appropriate sprites.

Editor Improvements

• Appearance/Form editor dialogs: comprehensive form previews with optional shiny preview.
• Ability selector: slot-based (A/B/H) replacing raw dropdown; hidden for Gen 3/4 where slot is a no-op.
• Moves tab: type and category icons shown per move.
• OT/Misc tab: AffixedRibbon dropdown, IRegionOrigin (country/sub-region) fields.
• Met tab: BattleVersion and Obedience fields added.
• Origin mark & Favorite flag UI added.
• IV/EV fields: maxed values now visually highlighted.
• Edit form now scrollable/responsive with sticky header and tabs.

App / UI

• App update badge: pulsing indicator on the menu button when a new version is available, with one-click reload.
• Persistent settings: theme, HaX mode, and other preferences saved across sessions.
• Theme-aware startup: no more flash of wrong theme on load.
• Improved save-file tab layout and overflow handling.

If IVs are increased in this tool, will they retroactively apply and increase stat values? For example, if the IV for HP is increased, will this then reflect in a higher HP value for an existing Pokemon?

Yes, of course. It should in fact happen in real time - watch for your max HP to increase / decrease as you adjust the IVs for the Pokémon. Bear in mind, the stat formula means small adjustments will be more noticeable at higher levels.

I suggest you do a bit of reading / watching videos to learn how stats work before you mess around: 

Happy Pokémon day everyone! I've added legality checks and fixes to PKMDS. Give it a try!

Hello all. Just some recent updates:

I've received several questions regarding what features will / won't be added to this app, particularly in relation to what PKHeX is able to do. I've created a detailed roadmap (with some help from AI) of all the work that needs to be done to match PKHeX feature-for-feature. Check it out here: https://github.com/codemonkey85/PKMDS-Blazor/blob/main/PKHEX_PARITY_ROADMAP.md

Just FYI all, I'm doing some work on the design tools, and in doing so I introduced a bug that results in the app looking wonky. I'm working on it and should have it fixed soon.

Hello all! Just a quick update: as of version 2025.12.23.0, support for drag and drop has been added! This has been the top wishlist item on my mind since the beginning, and I finally got around to it (with a lot of help from GitHub Copilot). You can drag and drop Pokémon to reorder them in your party, to reorder them in a box, or to transfer between party and box. You can also drag and drop a Pokémon file (.pk9 etc.) into a slot to import it into your game.

There are some limits:

1. You cannot drag and drop a Pokémon out into your file system. Sorry! I tried, but there were complications.
2. You cannot drag and drop to transfer between party and box in Let's Go Pikachu / Eevee. You can still drag and drop to reorder your party though.
3. It doesn't look like iOS / iPadOS Safari supports drag and drop. Your mileage may vary on other mobile devices / browsers!

Enjoy!

Hello Sir codemonkey85, I wanted to reach out and say I'm a new fan of the PKMDS web tool! It's so clean, easy to use, and honestly, I find the web interface better than PKHeX for quick edits. I noticed when im on the websites that its stuck on the loading screen when I try to load it. Is the site down for maintenance right now? Thank you for all your work!

The site doesn't go down for maintenance. If you weren't even getting the loading screen, I'd say GitHub Pages might be down. But if you are getting it, it's probably something else.

Hi, I just wanna thank you for the app first, it definitely made my post game SV so much funnier. But now I tried for the first time use it with my ZA save and I simply coundn't export the save file. It works exporting pokemon files, but nothing happens when I click "export save file". There's something wrong with my save? Am I not alowed to make any kind of changes like making a Galarian Slowbro Alpha or something?

This issue should be resolved by now.

Excuse me sir, i have this export issue where i do hit export then the save file is at 0b, it means it didnt do anything, any suggestions?

I'm using the yellow version

I've been getting reports of this lately. I think it's an Android Chrome issue - I've heard FIrefox on Chrome doesn't have this problem. I'll see what I can do here.

Will the online editor ever support Legends ZA?

Support for Pokémon Legends: Z-A is now available. I had to wait for PKHeX.Core to update, then I needed a save file or two to test with, then I had to actually code the changes. These things take time.

@TDotGill Sorry but no, PKMDS will never support ROM hacks.

It never even occurred to me that somebody would subtract to get to 31. I’ll definitely have a look at that.

@codemonkey85 Is there a way to add Mark on SwSH and ScVi at the moment since I tried finding all the section and initially thought it was on cosmetic but can't find any. If not is there any plan to add it in the future? Since right now I cannot use PkHex with .network requirement so your web app is really much appreciated to me.

Yep, I can add that to the list.

Does this work for fan games such as insurgence?

No, fan games / hacks are not supported. Official games only.

Hey, thanks for the awesome web tool.

I have a problem when loading mystery gifts for gen 3 games. After choosing the wc3 file, I get the error "The file is not a supported Mystery Gift file.". It seems, that PKHeX needed a plugin to read wc3 files.

I attached a mystery gift and save file to recreate the error.

E - Item Old Sea Map (JPN).wc3 1.22 kB · 1 download Pocket Monsters - Emerald (Japan).sav 128 kB · 1 download

Interesting. I believe there is a way for me to support PKHeX plugins, but I haven't really dug into that yet. Thanks for the info and the test files. I will add this to the list as well.

@Kaphotics I don't think I'm doing anything particularly weird here? User chooses an ability, and I use PKHeX.Core.CommonEdits.SetAbility() to set it (for Gen III).

If you're curious, this is what the code looks like: https://github.com/codemonkey85/PKMDS-Blazor/blob/2650efd07189eabe7b3f1cc8d91835997f22527c/Pkmds.Rcl/Components/EditForms/Tabs/MainTab.razor#L276

@bind-Value:set="@(ability => Pokemon.SetAbility(ability))"

@PkmnHack I can’t seem to figure out what issue you’re talking about. Can you send me some instructions and a screenshot of what you’re seeing? It looks to me like the abilities are working perfectly normally.

When I attempt to put a new pokemon on the save file do I have to add/make the PID or will it do so automatically? From what I understand is it's important but, don't fully understand PID yet. 

Yes - I do need to improve the process for creating a new Pokémon. I might just add a random PID button.

On 3/21/2025 at 12:39 PM, PkmnHack said:

Why does the pokemon ability say "No special ability" even if I chose one ability!? This is happening only on gen-3.

I will look into this to see if I can replicate it. Can you share your save file?

For some reason, even though I'm able to edit or add items in my bag and export the save, the items don't actually show up in my game.

I noticed that in your save file, you have several items with a set quantity of 0. I suspect those are the items not appearing in your game?

@LavndrScared In order to change the species on that dropdown, you have to type a name to search for. I had to make it work that way, because 1,000+ names don't render super great on a web page.

Thank you for using my app!

I'm aware that some iOS versions simply don't load the app, and it just gets stuck in the loading screen as you mentioned (see this thread)

@arleypadua You may want to consider disabling SIMD for WebAssembly. I did that to widen support for older versions of Safari. See here: https://github.com/codemonkey85/PKMDS-Blazor/commit/185d448809e365449b647d9480ae5b2d782edee9

Was a bug in PKHeX.Core for D/P, and has been fixed: Gen 4/Diamond - Injected wondercards do not activate gift flag · Issue #4407 · kwsch/PKHeX

How to work around it for now? inject both the PGT and PCD. If codemonkey85 wants to add another workaround, I think setting the gifts in reverse order will allow PGT-slot0 to retain its "isActive" status.

Thanks for the head's up Kurt - I will look into this. I assume this workaround will no longer be needed once you update your NuGet?

Why is the Sprites for Pokemons not showing now?

Try refreshing the page. I made a change to the project structure, including the way the sprites are stored, so if you aren't on the latest version it might not show images correctly.

I need help for FRLG

when I tried loading the Mystery Gift file it keeps telling me the file is not a supported Mystery Gift file. I tried loading a .wc3 Mystic Ticket I found.

Would appreciate some guidance on this please where can I find the correct file for this?

Can you share the file you're using?

@eclaire9 Glad I could be helpful. Yes, I am planning feature parity with PKHeX, it’s just a question of timing. This is still just a hobby project.

I’ve been asked a lot about legality lately, so I might prioritize that soon.

Sure @Azarelic, I can look into all that.

@TRIFORCE89 The issue with exporting / importing Pokémon files has been resolved. The app is currently building / deploying (https://github.com/codemonkey85/PKMDS-Blazor/actions/runs/13554425763). If you reload the page when it's done, you should get a prompt to update shortly after.

@Bigbrompton I'm not seeing any issues with changing Pokémon data. Are you hitting the 'Save' button on the Pokémon editor screen when you're done?

On 1/27/2025 at 12:48 AM, Dawson Smith said:

Hello, so I was able to upload and edit a Pokémon however when I click on export the file it doesn’t do anything. I’m on chrome and doing this from my phone. Any help?

What steps are you taking exactly? i.e. you can't upload a Pokémon and edit it, so I assume you're uploading a save file and editing a Pokémon in that file?

On 2/1/2025 at 1:51 PM, TRIFORCE89 said:

This is pretty handy on a Mac. But suddenly I think the Pokémon exports are invalid? I can no longer export a Pokémon and import it back in. It says "The file is not a supported Pokémon file."

I'm playing Generation I, and was doing this to cheese in-game trades (retain my creature and benefit from the trade).

Looking at the exported pk1 files in a hex editor, they seem sparser than the ones you can download here.

I think I see the issue here. Working on a fix now.

I cant seem to change the nature of the pokemon, also stats. I press save then export. I load up the game and it doesnt change the stats. Adding items to my bag works, so I know the save game is working.what am I doing wrong?

this is on soulsilver on mobile delta emulator

I will look into this.
