Remove the Tera Finder plugin and wait until there's an update for the latest PKHeX release.

This plugin is part of the unmaintained plugins of foohyfoohs Plugin Pile. It got updated for PKHeX 24.03.10. You could try that.

It's now possible since PKHeX 24.03.10. The palette can then be changed in the block data editor.

• 0 - Red
• 1 - Blue
• 2 - Green
• 3 - Brown
• 4 - Orange
• 5 - Greyscale
• 6 - Full Green
• 7 - Full Brown

Open the Block Data editor, search for PokedexNationalMagicFRLG and set it to 185.

The national dex flag should now work correctly since PKHeX 24.03.10.

That symbol means the Pokemon is illegal, it can not exist in the game like that. You have done something wrong when you created it.

Hold Ctrl and click on that symbol, you will see a detailed legality analysis which will tell you what's wrong.

It is recommended to not create something from scratch but to use the Encounter Database instead (Tools > Data > Encounter Database). Search for the Pokemon you want and PKHeX will create it just like the game would. You can do your modifications afterwards.

Also keep in mind that in gen 3 IVs, nature, ability and gender are connected to the PID. So if you change any of them without inserting a new proper PID, the Pokemon would become illegal. PKHeX won't generate the PID for you, you will have to use Pokefinder for that.

Thanks, Do you know how to know the country and subregion number of the 3DS?

Check PKHeX's source https://github.com/kwsch/PKHeX/tree/master/PKHeX.Core/Resources/text/locale3DS

Alternatively, set the values you want in the main GUI editor and let the program indicate the current GUI's value beneath the drop-down selection.

Upload your save.

On the transfer from Gen 3 to 4 the met level is set to the Pokemons current level.

When I try to open a save of Pokemon Gen3, I can't choose all habilities. it's how pkhax mode are disabled but it's on. How can work this for gen3?

You can not choose any other ability because that's technically not possible in Gen 3. The ability is just a single bit which can either be 0 or 1, depending on if the Pokemon has its first or second ability.

You can not just get it from your SD card. You need to have a hacked Switch and use JKSV to get it:

LeafGreen is only filled with garbage, Ruby is mostly garbage as well.

I am on the latest PKHeX 23.12.18.

Latest is 24.01.12.

That depends on what exactly you are trying to change. For Lucario the ability, IVs and nature are fixed and can not be changed.

Empty as well.

There's no data inside, only garbage, nothing to recover.

Nothing to save unfortunately.

That file is empty. Doing modifications in PKHeX, even illegal ones, won't clear a file like that.

Use ALM.

Use JKSM or Checkpoint, if you export the Extra Data from the game you should get a folder that has your battle video files. PKHeX is able to import your teams from those files.

WIth a hacked 3DS it would be possible.

Upload the save.

I saw on youtube that there is a pkhex that can open this file

The latest version can do that just fine. If it doesn't work for you something is wrong with your save file. Using emulator functionality does not create save files. That's why Kaphotics said you need to save ingame, as you would do on your Switch.

Fixed.

I don't know the Anbernic devices, but you should check if they have any settings to change the save size to proper 128KB. 64KB works until you reach the E4, then the game does not have any space for the Hall of Fame data, so it overwrites 2 of the existing save blocks. In your case blocks 6 and 7 were affected and the game won't load if any block is missing. So unfortunately if you had anything stored in your boxes 3 - 5 it's gone as it was overwritten by the HoF.

Try using TWL Savetool instead, the latest versions of Checkpoint seem to have issues with NDS games.
