i cant quite figure out how to randomize PLA and there is no videos online helping at all. how would i go about it? when i tried opening wild encounters in the master dump it says:  System.IO.FileNotFoundException: Could not find file 'C:\Users\me\Desktop\emulation\switch games\pla rom dump\romfs\bin\field\encount\new_huge_outbreak_group.bin'.  whwn i try pressing any of the other options under the master dump section it just makes the error noise and doesnt open or show anything. what can i do here? im stumped

Dump the entire ROM as well as the latest patch. You need to be on the latest patch, as the program is designed to operate on the most recent release of the game data.

Hello,

I want to try randomized pokémon games so I followed few tuto on Youtube and every video put links to a github page that leads to an Azure one but I can't find any button to download the software anywhere on this page.

Thank you in advance for your help.

Read the first post in this thread rather than referencing old YouTube videos.

Hello,

I downloaded the latest version of PKNX and tried to randomize my game after dumping the romfs and exefs from my Pokémon Sword copy on my Switch. I copied those folders from my SD card into a folder on my PC, then opened the PKNX application.

I tested a few features, and after randomizing some elements, I closed the app, transferred the modified romfs and exefs back to my Switch, and launched the game. Everything worked fine.

This time, I wanted to do a clean randomization without changing everything, but I can't seem to restore the game to its original state in PKNX. I deleted my save file on the Switch, uninstalled Pokémon Sword, reinstalled it, and dumped the romfs and exefs again.

I even deleted and reinstalled PKNX, but no matter how many times I try, the “Static Pokémon” option stays randomized. It's still showing Haxorus with ID 00 instead of resetting to the  default values. Unless this is normal? But it doesn’t seem like that’s the default state, right?

The program saves the layeredfs folder next to the executable. To remove any previous modifications, remove the layeredfs folder.

Le programme enregistre le dossier layeredfs à côté de l'exécutable. Pour supprimer toute modification antérieure, supprimez le dossier layeredfs.

hi , Alright, I checked, but there’s no “layeredfs” folder in the program’s directory, and not in my folder with the romfs and exefs either. Where should I go to find this folder and delete it? 

Edit : When I make a change with PKNX and then close the app, it does create a folder with Pokémon Sword's title ID next to romfs and exefs. When I delete that folder, it does seem to remove the changes I made at that moment — but the Static Pokémon data still doesn’t reset. It stays in its randomized version with Haxorus as ID 00.

(Sorry to bother you ) Do you have any idea of what can i do ?

Hello, it's me again. I've been trying several things over the past few days — uninstalling and reinstalling the game from scratch, dumping in raw format, avoiding dumping into the LayeredFS folder, trying to run PKNX directly from the SD card, and even deleting the LayeredFS folder using DBI.

But no matter what I do, the “Static Encounters” still show Haxorus as ID 00, along with other modified IDs that remain unchanged.

I’m out of ideas at this point, so I’m asking here again and hoping someone can help me, please.

Even when a friend gave me her clean romfs and exefs, as soon as I load them in PKNX, the “Static Encounters” still show Haxorus with ID 00, along with other altered entries. I dont know what to do else

I need help with randomizing the items found on the ground, can someone help me by explaining what I need to do? I’ve already tried randomizing in the 'placement' section, but it didn’t work.
