Chao Editor Redux

[Gizonde]

lolllllllllllll

so I woke up today and had a really stupid idea that actually works. It's pretty gimped but hey. You know how I said the PC save looks similar? Well, try "exactly the same with a different name."

1. Use a memory editor to change your Chao data in game on PC. Save and quit. Addresses to care about are all static to boot with no pointer searching involved.
2. Go to the save data folder and rename the file savedata.bin.
3. Replace the file in the container file on your 360 save with that one.
4. (probably not required) select storage device instead of continue when loading up Chao garden.

Verified by making a baby Chao into Amy chao on my 360.





You can probably reverse the encryption with stack traces but this is way easier for me.

for really lazy, chao type on chao 1 (basically a starting point) is 019F7744

edit: well, almost the exact same
reverse importing had some side effects


(yooooo)

it keeps saying its not the chao data and i know it is

The program works for Sonic Adventure 1 chao data, but it will not open SA2 chao data. I'm not sure if you've implemented SA2 support yet, as your post suggests you have. If it is supposed to, am I doing something wrong? Horizon was entirely too buggy to use to extract the saves, so I used Modio instead to extract the saves from a USB flash drive. Sonic Adventure 1 works, and Sonic Adventure 2 does not.

Everything is already found. I just don't have a fix for the checksum yet. It's going very slowly.

Which game?

Sonic Adventure 2 isn't implemented yet. It only works for SA1 at the moment. I'm working hard to break security. I'm sure it's a simple check, but I've never coded a fix for security before. I promise that I'm working hard to get it out. Please be patient.

Sonic Adventure 2 compatibility has been added. It is NOT a simple check! In fact, it is a custom hash. However, with the help of a few others (listed in the credits), the hash fixer is now out! Updates will be much more regular now. ;)

Right. That is one of the changes. The program now requires that you extract savedata.bin from the save file. It's just all around more stable that way. It's also the only way to fix the hash for SA2.

can you mark with boxes do what i know the second line down is the fly stat and i think the bottom two are the luck and inteligence
also you might want to limit the luck and inteligence stats to 100 or whatever their normal maximum is in game as when i had them set to 9999 and he was stupid as hell (with the jack in the box he just refused to open it like he had zero inteligence).
also limit fly to about 3500 - 4000 as when i set it to 9999 he flies right out of the race's area everytime

Edit: yeah looks like 100 for luck and inteligence is just about perfect but i guess the strength is now too high as it shakes trees for too long aswell.
