I don't have any CAWs on 2k24 yet, but if it's the same as the in game superstars, it should always be the 3rd byte of the AOB.
For anybody needing some tips on finding AOBs and messing around with gender bytes, maybe I can help with this advice...
The first 2 bytes of somebody's AOB are their ID, like how The Rock has been ID 100 for like all of eternity in these games, which means the first two bytes of his AOB are going to be 64 00 because 100 converted into bytes (as in the Array Of Bytes that is an AOB) is 64 00.
After that we get to the 3rd byte, which is the gender byte and will always be 00 or 01 (00=male; 01=female).
Now let's do a little test to see if we can find somebody's AOB. Let's take Becky Lynch who we know is ID 611 because this google doc for 2k23 tells us, and the IDs usually always stay the same year after year. The AOB patterns (the HEX values in the second column) are out-dated on this Google doc though, so we have to figure out the pattern ourselves. So since we know Becky's ID is 611, we have to convert that to hex which is 263 which we then have to make AOB-friendly by turning it into two bytes like this 02 63 but then swapping them so they're like this 63 02 which gives us the first two bytes of her AOB. If these last couple sentences sounded f'n psychotic and made no sense, do some Googling on how to convert decimals into hex into array of bytes. It's valuable info to know, but tricky to explain easily.
Next, we know Becky's female (despite being The Man LOL!) so we know the 3rd byte will be 01. After that, most of the time the 4th byte is a 00 followed by another occurrence of their ID taking up the 5th and 6th bytes in the AOB. So that would mean this pattern should find all instances of Becky's AOB:
63 02 01 00 63 02
^First two bytes represent the character ID, 3rd byte is gender, 4th I don't know what it's for but it's usually 00, and then 5th and 6th are the ID again just like 1 and 2.
For most of the people listed on that document, you can kind of figure out what the AOB pattern should be just by looking at it. For example if I look at Asuka it says her pattern is
6D 02 2F 01 6D 02 ...but we have to adjust for the fact that the 3rd and 4th bytes (in red) in all these suggested patterns is out-dated now. So with Asuke above, I would replace byte 3 with 01 because I know she's a female and I know her gender byte will be 01. Next, as I said earlier, the 4th byte is unknown to me but USUALLY is 00 now. So I'd come up with this new pattern if I want to search for Asuka:
6D 02 01 00 6D 02 ...and this would probably find her, but I'm just guessing. If if fails, I'd replace that unknown 4th byte (00) with a wildcard (**) like this and narrow my search from there: 6D 02 01 ** 6D 02
Anyway, I realize this strayed off a bit from the original question regarding CAWs but once you get really good at finding and editing in-game superstar AOBs, then you start getting a lot better at dealing with CAW stuff too. You can usually find a CAW's AOB the same way, but with CAWs that have smaller ID numbers it definitely gets trickier. Usually the first CAW you create is going to have ID 1, and the second will have ID 2, and so on... In 2k23 I was able to find CAW AOBs using the method I describe above (First two bytes = ID, third = gender, fourth = 00 or wildcard, followed by the ID being repeated again) so it probably is all the same in 2k24. Hope this helps some people out with their experiments!
Don't forget everybody has SEVERAL different AOBs in the game, so if you change the gender byte and it has no effect, you may have changed the wrong AOB.
