Hex Editor
The Hex Editor is an incredibly powerful, and potentially intimidating, tool PKSM provides you for editing your Pokémon. It can be accessed by tapping the block of purple letters in the upper-right corner when editing a Pokémon in the Editor. When you first open it, you'll be greeted by a screen that looks completely different from the other Editor screens you've seen so far.
The top screen shows the Pokémon you're editing in raw hex. The byte that is currently selected has a box around it, and it's purpose is briefly described at the bottom of the screen. If a byte is grayed out/disabled, you will need to unlock it before you can change it.
The bottom screen shows the index of the currently selected byte, it's value, and sometimes a translation of the value into a more understandable version (like the Species bytes). For bytes that are unlocked, there are also editing controls in the form of plus buttons above and minus buttons below the value of the byte and/or labeled boxes for toggling flags kept in that byte.
There is a learning curve to using the hex editor. You will need to be able to convert values between decimal and hexadecimal (you can easily find a tool to help with this online). For those fields that don't show as a number in-game, you will also need to find some kind of reference for what values mean.
The controls are pretty simple: navigation is done with the d-pad or circle pad and edits can be made with A (increase byte's value), X (decrease byte's value), or the touch screen.
While PKSM's normal editor screens allow you to change many of the details of your Pokémon, there are some things that don't appear on them. In order to edit those you will need to go into the hex editor and find the appropriate byte(s). The tables below list all of the exclusive fields for each of the supported formats that you can edit. Lock Lv. represents how many times the hex editor needs to be unlocked in order to edit the field's value.
For fields that span multiple bytes, be aware that Pokémon stores data in little-endian format.

You may see this called different names at times, such as:
- God mode
- Easter Egg mode
- super hex editor
Bytes that are locked (greyed out) are like that for a reason: it is usually far more dangerous to edit them compared to unlocked bytes, especially if you don't know what values are legal for the particular byte.
It is possible to unlock them (see screenshots below), but you will not be told how to unlock them. If you really want to know how, we insist you figure it out yourself and direct you to read through PKSM's code.
