PKHeX on Web

[arleypadua]

After a bit of effort I put recently on writing a terminal app to edit pokemon save files in any platform (Windows/Linux/MacOS), making it accessible to install with a simple terminal command, I realized that some of it could actually be ported to a nice UI accessible on the browser.

If you want to jump right into it, go to: https://pkhex-web.github.io

I finally released this working version with a couple of features fully funcional:

• Open/Export save files
• Visualize trainer data
• Add/Remove items
• Add Pokemons from the encounter database
• Edit Pokemons (party/box)
• Legality warning
• Extendable with plug-ins
  • Auto legality mode plug-in

I'm trying as much as I can to make it responsible to work on big screens or mobile-ready, but there may be some aspects that are broken (if you find any, let me know on GitHub)

The repository is the same of the CLI for now: https://github.com/arleypadua/PKHeX.CLI

If you like what you see, share your feedback or issues here: https://github.com/arleypadua/PKHeX.CLI/issues

Again, none of it would be possible without the efforts put into making PKHeX.Core, so kudos for the team.

Hi, I am trying to edit a Pokemon Emerald .sav save file. Is that possible with the online version or with the linux CLi tool? Both seem to throw an error:

Error: The file at Pokemon - Emerald Version (USA, Europe).sav did not load into a save file.

I also tried bunch of winetricks(wineprefix with latest pkhex and .net 8 installed), mono(directly executing latest pkhex .exe with .net 8 runtime on my linux), to get Pkhex on my linux machine. But nothing seems to work... Any ideas ?

If the file os not loading into a valid save file, it means that PKHeX core wasn't able to load it.. 

Most of the time, when it happens, it means that your save file is either corrupted or invalid.

I tried opening an Emerald save file as an example, like this one and it works.

So I'm guessing it is likely to be your save file.

I can double check if you send me you save file through GitHub or https://filebin.net/

Looks like amongst all the confusion and installing 5 different softwares, I lost track of the folder where i had the save file. I was trying to open a save file that hasnt started the game yet , could maybe add error handling for that if the library allows it.

Totally my fault. The correct save file works, as does yours! Good job writing this tool and thanks for the answer!

I have another question:

I am trying to create a team for the battle tower, what would be the right tool for that job? I thought i could manipulate the IV's, EV's, nature, PID, but I just press enter and it scrolls to the top?

Glad you found the issue... It happens

Right now the tool only allows you to edit/v clone Pokemons you currently have in your party or box.. I'm slowly adding the feature of adding Pokemons from the encounter database.

Not sure if I understood your issue, but there's no need to press enter, just enter the number you want and export the save file. For instance, to change the nature, select the new one on the drop-down, go to the menu "Save" on the left, and export it.

Does it work for pokémon past generation 3?

It should support the same versions PKHeX for Windows supports, as it's based off the same foundation

The web page as well? The reason I'm asking is that i'm playing the emerald ROM hack Run and Bun which has pokémon up to gen 8. When I load the save file on the web page my Chimchar shows up as an Anorith with the nickname Chimchar.

ROM hacks are not really supported, unfortunately, as their save file structure differ quite a lot from the original games.

Oh ok, thank you for quick answers:)

Have been using this extensively for a little over a month, it’s been a life saver for fully playing on my iPhone. Just wanted to say thanks for making and sharing this!

Thanks so much for this dude! Noob question, maybe this is unrelated; is there any way to make the game play faster? I tried to fast forward using the settings on the retroarch browser emulator, but it won't do anything despite everything I've tried lol. Maybe I'm doing something wrong?

If you're running somewhere having a keyboard (like a PC or macOS) you can configure the key bindings and set the toggle_fast_forward to some key, like tab.

However, if you're running on a phone that's not yet possible.

This plug-in is in very early stages, just experimental, although playable, it is far from being polished

I have a problem when exporting sav file using the PKHex on web, somehow it only exporting into .txt no .sav

So I can't load the exported sav file that has been modified on PKHex on web to Citra emulator.

Thanks for the feedback, today I release a version with the fix

Is there a way to edit a Pokemon's PID with this program? I may be missing it, I only see an option to copy the PID.

Did you set the Pokémon back to the slot once you were done making changes?

[AppaGab]

I cannot thank you enough for this, Mr. Padua!!! An excellent service for all fellow pokemon fans

Which game version are you trying to edit? Tried to produce but it works every single time I try.

How can I add pokemon in the box? Because I only can enter the name of the specie

You need to select the game version so that it correctly filters the possible encounters

The web version isn’t working not loading not sure if it’s a server issue but can it be fixed asap please thanks

There's no server in this web version, except for collecting some usage analytics, which doesn't affect the usage of the app.

Has it worked before for you? If so, you could try opening it in your browser incognito mode, if that loads, I'd recommend cleaning your cache and opening again.

Furthermore, just tried myself and it is working normally.

I tried those just now and I’m still getting the same thing on my phone. The web version is stuck on the loading screen it doesn’t load
