PKHeX guide or whatever

How to use PKHeX for retards - Make your Pokémon so I don't fuck them up

If you never used it before USE THE ENCOUNTER DATABASE (Tools>Data>Encounter Database). Change OT version to one of the new games. Choose your species and search. The best ones to pick are either an egg (has an egg icon, cant have marks) or wild encounter (grey background, can have marks). Green/purple are raids and pink is a fixed overworld encounter, all 3 have more rules making it harder to edit. Pokémon with a pokeball are ball locked. Use those at your own risk.

Click the tick/warning next to your Pokémon's icon as you make changes to check if it is still legal or not.

Use your own SID/TID when making Pokémon:
You have to have a save file loaded first in PKHeX before you make Pokémon for it to not use PKHeX as the default trainer. This file has the following as a template SID: 1234 and TID: 123456 and the trainer name "Anon" https files catbox moe 415b56.
Load that file in PKHeX and then you can change the TID/SID/OT by going to the SAV tab and then clicking Trainer info and putting in whatever your info is. Then you can file>export sav and that way all you have to do when you want to make Pokémon is load your main file and all Pokémon you make will have your SID/TID/OT.

Screens:

Main:
PID - Click the star to make it shiny, reroll makes it normal (changing TID or SID changes shiny status)

OT/Misc:

Common errors:
"Unable to match an encounter from origin game" - This is usually fixed by changing the met location/met level. Left click on "Level:" in Main tab of PKHeX to get a suggestion. If that didn't fix it then you messed it up real bad, start over and check legality after each change to see what you are changing that's making it not legal

Ghouldengo - Start with gimmighoul, change to ghouldengo, change form argument to 999 and change level to 1 level higher then met level.
Dudunsparce three segment - Start with dunsparce, change to dudunsparce, make at least level 32, change form, in OT/Misc tab you need to change the Encryption Constant. It is a hexadecimal number, use a website to convert from hexadecimal to decimal, copy number and change it to be divisible by 100 (eg 60883647 changes to 60883600) convert from decimal to hexadecimal and change Encryption constant to new value.
