Aside from being a blatant advertisement of my own CAW, do you see anything off about this picture?



That's right, REX's stats are souped up to all hell. He's got Hua Xiong's 'Action' while having Zhao Yun's Dragon Spear! How the hell did that happen?

Simply enough, this was achieved through hex editing.

Hex editing allows you better freedom over editing your CAW. If you have a memory editor (Cheat Engine or HxD), it's pretty simple to just change a few bytes and have a better CAW come out of it.

As I am a horrible teacher but instead prefer to research random crap on my own, I've compiled a few records and will be putting what I've researched so far in this guide. The guide assumes that you're already familiar with memory editing mostly because I can't explain it myself oops.

These are pages of a study I made on エメベアー 's CAW listed on their guide.

https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=2715382933

That guide is also pretty much a prerequisite reading for this guide especially the pastebin so go read it if you haven't.

https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=2731906868

https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=2731933015

Below this follows a list of IDs you can use when making your own CAW.
Do keep in mind that there may be bytes and IDs that I was unable to catch.

a.k.a. why the bottom portion of the CAW memory array is simultaneously your best friend and worst enemy

If you're the type of guy that likes to frequently open their CAW files and make minor edits from time to time (nothing wrong with that, I do that too), you might want to consider turning back first before you hex-edit a CAW you like.

Hex-editing, especially in the purview of moveset modifying, is very fickle. It changes EVERYTIME you switch to a new screen on the file. Your modifications, if you have made any, will reset if you open your CAW file! If you have modified any of the following, they will be reset to their original settings:

• Favorite Weapon
  
• Signature Style
  
• Stats
  
• Troop/Empire colors
  
• Voice

Here is REX, a happy boye with hex-edited stats and Hua Xiong's specials with Zhao Yun's Dragon Spear as his moveset. For some reason, I've pressed onto his CAW file! Oh no!




Okay! I'm inside his CAW file, and I am free to modify whatever I want! Maybe I should give him a haircut? Nah... maybe not. Then, I will just press ESC to go back to the earlier screen. His stats are still there, so they should be fine, right?




Unfortunately, all was not fine. REX's hex-edited stats have disappeared, and so has his special moveset. The reset also happens if I went into any tab while inside the CAW!

This means that if you really wanted to make some modifications stick, you'd have to resign yourself to not touching the CAW file if you don't want the hex-edits to disappear. Though really, you could just reapply the hex-edits if you really wanted to modify an existing CAW.

Memory editing's weird, huh? If you were to apply a modification while inside the CAW's file, it would reset as soon as you saved the file.

This will probably be updated as more DLC comes, and will be filled out comprehensively once the English release comes out.

Have you ever downloaded a really cool CAW only to realize you couldn't edit it at all?

What if I told you... that can change? >:DDD

These two bytes are located just before the Weapon Proficiencies.

[Gender]

Be careful with assigning genders! You can delete your entire CAW like this!
00: DELETE
01: Male
02: DELETE
03: Female
04: DELETE
05: Male, Favorited
06: DELETE
07: Female, Favorited

[Child Checks]

It's worth noting that characters that aren't children WILL get their Weapon Proficiencies reset.
This is also where you can set downloaded characters to be edited, like they are supposed to be.
00: Not a Child (Weapon Proficiencies reset)
01: Not a Child (Weapon Proficiencies reset)
02: Detected as Downloaded, Not a Child (Unable to be edited, Weapon Proficiencies reset)
03: Detected as Downloaded, Not a Child (Unable to be edited, Weapon Proficiencies reset)
04: Child
05: Child
06: Detected as Downloaded, Child (Unable to be edited)
07: Detected as Downloaded, Child (Unable to be edited)

alright so I think I gotta explain the trio of Signature Styles, Favorite Weapons, and Action a bit more indepth because these three bytes have some SERIOUS potential when edited properly

Let's tackle each one from top to bottom.

Action
The Action byte is located at the upper portion of the CAW's memory array, just in between the voice and CAW type bytes. More simply, it's what dictates what your CAW's Musou and Special Trigger Attack.
Most people assume that the Action byte has absolute control over the CAW's signature style and weapon, which is untrue.

Favorite Weapon
The Favorite Weapon bytes are an array of four bytes located in between the bottom portion of the CAW's memory array, in between the stats and the parent bytes. The game recognizes weapon IDs and modifies the following:

• CAW's default weapon
  
• Weapon used in Musous & Special Triggers

Signature Style
The signature style byte is located just after the parent bytes at the bottom portion of the CAW's memory array. This is the byte that determines if your CAW is eligible to use exclusive Flow & Trigger attacks.

How does the Signature Style byte interact with the Favorite Weapon byte?
First of all, you must understand that in order to use exclusive Flow & Trigger attacks, the CAW must fulfill the conditions of:

• Using their favorite weapon
  If the CAW is not using their favorite weapon, they will be unable to use exclusive attacks. This is the reason why a CAW using Xiahou Dun's style cannot equip the Nine Rings Blade and have their exclusive attacks follow them onto the weapon.
  
  In order for a CAW to use Xiahou Dun exclusive attacks on a Nine Rings Blade, they must change their Favorite Weapon byte from 09 00 (Podao) to 0A 00 (Nine Rings Blade).
  
  
• Having a compatible signature style
  This got me ucked fup. You can only use signature styles on weapons they're intended to be used on. The reason why Xiahou Dun's signature style works on Nine Rings Blade is because they're clones of each other.
  Weapons that are not identical to each other cannot have differing signature styles.
  This means that if you put Lu Bu's signature style on a Shadow Fan favorite weapon, you wouldn't receive any exclusive moves. You won't be able to use Lu Bu's OP Launch Trigger on it. Sadly.

The Action byte governs only the Musou + Special Trigger attacks.
The Favorite Weapon byte governs the CAW's default weapon.
The Signature Style byte governs the CAW's exclusive Flow & Trigger attacks, if eligible.

If you work around it properly, you can make a custom moveset (to an extent)!

Take for example:
Set your Favorite Weapon byte to 18 00 (Dragon Spear)
Set your Signature Style byte to 0C (Zhang Fei)
Just from here, you already have a unique moveset! You have Zhang Fei's unique attacks with Dragon Spear, something the base game doesn't allow!
But you haven't set the Action byte yet! Set it to 10 (Lu Bu)
And damn! You can chokeslam fools that are actin' up too? That's a 10/10 moveset right there man
