The Beginning
all you need it's :
- 1 Wii with homebrew channel (with Memory card port of course)
or a memory card with a sd port on it
- 1 memory card NO NINTENDO OFFICIAL
- SA2B GC and PC (or SADX, i guess that work too)
- 1 SD Card format FAT32 or USB FAT32

Programms :
- GCMM (this one is a homebrew for wii)
- Fusion chao edit
- hex edit (Hxd is the best)
Copy the GC chao save to SD card (for wii user)
for user that's gonna use a memory card with sd, i don't have one, but that should be easy to move a save to another memory card that contain sd
try looking in the internet how do that work before buy it


download the homebrew GC http://wiibrew.org/wiki/GCMM for export the save to sd card
(google it for know how to install homebrew apps)
turn the wi ON and go to homebrew channel, you will see GCMM's here, launch the homebrew and you will see THIS :
press A if you want to export to sd card (or B for USB) but i use SD card so i press A
now you have this















with the wiimote, choose BACKUP by pressing (-) or Y if you the GC controller...
attention, after choose the mode the homebrew will tell you the slot GC you want open (A or B)
after doing that, you see ALL your save but we need to found the chao save and it's SONIC2B_ALF







press A to start backup, and when it's done you got "backup complete"
now leave the homebrew and turn off the wii if you want

insert your sd card/usb in your Computer, you have MCBACKUP folder with your save her, CONGRATULATION ! you have YOUR CHAO GC save !
Load your GC save in the PC version
this one it's EASY, all you need it's a programme HEX EDIT (i use HxD)
with hex edit, open your GC save and PC save (MAKE A backup for PC Save, i swear you need the backup later !)

First, make a backup of your pc save, because you're gonna need it
now you have 2 pc save, 1 that's gonna be your "broken gc save" and the another that is actually your true pc save

open your GC save with Hex edit and copy the line 00000040 to the END

















then open your 1st PC save with hex edit (this one is gonna be your "broken gc save") and paste (more like REPLACE) all the code like this

when you are done, launch the game, go to chao world and see if it's work, if yes, you see only the chao garden open, DON'T GO IN, stay in the lobby and open chao fusion editor
look your GC chao are here !

Now EXPORT ALL YOUR CHAO you want to go back to PC (yourchaoname.chao)[/spoiler2]
Convert the GC CHAO to PC CHAO
sadly, The gc chao imported to PC, are "corrupted", the stats is glitchy, the evolution, toys, age, everything is broken
but don't worry ! we can fix it !

first let me explain why the gc chao is broken in the pc version :
the value of pc chao compared to gc chao are reversed, here a example, the chao in the GC version have 1250 on swim, let's do the same for the chao in the PC version
now if we export the gc chao save and pc chao save, the hex value look different !
in GC version : 1250 is 04E2
in PC version : 1250 is E204

so what happen if we put a GC chao to pc with 04E2 ? the stat is broken, the game will show 57860 on swim than 1250
same result if we put a pc chao to gc

basically the value of pc version is a mirror of the value of gc version
04 E2| E2 04[/i]

now you know what you're going to do, "Reverse" the value to make your GC chao work perfectly in the PC version

open one of your chaoname.chao file with Hex edit
then edit all the value that need to be edited, here the table with the line to the left and the value name to the right

the value with 2 bytes (stats, age, happiness,...)are easy to reverse here a example :
before the reverse : my gc chao stats value are :
e2 02, 77 00, b7 00, 0c 01, af 01, 7a 0a, a0 0f
after the reverse :
02 e2, 00 77, 00 b7, 01 0c, 01 af, 0a 7a, 0f a0
see ? it's easy, just change the value position
now my gc chao have the correct stats in the pc version (even int. and luck are correct)

the value with 4 bytes are kinda hard (run/power evolution, Magnitude,...)
Before the reserve : my gc chao Swim/fly value is :
3e 19 99 9a
after the reserve (look closely) :
9a 99 19 3e
and do the other evolution value (run/power, dark/hero (if it's a baby), magnitude)
and now my gc chao have his nice form in pc version !

the animals value are.... 3 bytes... kinda weird but alright !
Before the reserve : my GC chao animal value is :
01 09 0a
after the reserve :
0a 09 01
this one it's kinda easy too if you look closely, you don't need to edit the middle

now my gc chao know the true animal he learn

and by doing the rest (life1, life2, doctor medal, age, toys,...)
my gc chao is complety converted to PC version ! just like your chao (i hope you follow me)
PROFIT !
once you finish it, load your true PC save (the second one you made by backup) and import all YOUR fixed GC CHAO in your save ! awesome ! your gc chao are not broken ! just like mine ! Congratulations !
F.A.Q
What's the point if you can only remake ?
-> well remake it's a good idea too, and a simple way, but you will never know what toys your chao have, age, Intel and luck, his dna and more.. so remake your chao don't make you feel that you get your gc chao back

so we can have the official Tails chao from phantasy star online in PC version ? with the Jewel chao ?
-> YES ! awesome right ?

do that fix bright chao ?
-> well no, shiny two-tone chao in gc version will become bright chao, if you use chao world extended you can't import two-tone shiny in black chao mode save, it's something

do i really have to edit/reverse all the value ?
-> not really, you can still let run/power, swim/fly, Dark/hero, and Magnitude value and fix it with fusion edit for example

i don't have a wii hacked, is there another way ?
-> maybe.. you just need to found a way to transfer your GC save into SD card or usb

i used dolphin, how i'm gonna get my gc save ?
-> there a tool in dolphin about "GC memory card" so you can load your memory card file and export your GC save, and do the tutorial

my game say the memory card/save is corrupted, it's still possible to get just my chao gc save ?
-> i'm afraid that GCMM can't read corrupted save... :c but try there's still hope

is there a programms that gonna be creat for convert gc chao to pc easy ?
-> for the moment, no, but i hope someone can make one

i import my shiny chao jewel, but with the bright chao glitch, my chao don't look like the GC
-> Don't worry, you see the transparent color in Appearance from Fusion edit ? use it, disable shiny, enable two-tone, and select the color what you chao are in GC :
Shiny Jewel Red : Green yellow
Shiny Jewel Orange : Goldenrod
Shiny Jewel Green : Medium Goldenrod
Shiny Jewel Sky Blue : Pale Goldenrod
Shiny Jewel Blue : Pale Turquoise
Shiny Jewel Purple : Turquoise
Shiny Jewel White : Pale Green
Shiny Jewel Black : Pale Goldenrod (i have not idea for this one, maybe dark gray)
for invisible chao : select invisible 1

or if you chao world extended : enable the code 'Special Breeds' Effect, that will make almost all the shiny jewel chao like the gc version

I tried following this guide for a Chao in DX on GC to DX on PC (modded) and it did not work, however, I did end up finding another way to do it where I used a rom of Sonic Advance 1 to transfer a Chao from DX into SA2B and then I used a save converter to make the save file work on PC and then I exported the Chao to then import it into DX.

Can you do the reverse and bring PC chao to a modded wii?

my chao are aging too quickly after I use the fix, any advice?

Hey I am wondering if I could talk to you about some mechanics, I have this hypothosis regarding "Bright Chao", Mainly why it happens and possibily offer a window into fixing it.

Would you happen to know how i can also import my actual save file for level completion from my gamecube save to my steam copy?

It's been a long while since this was posted-- but I'd also love to know a way to do this in reverse... :(

Awesome work Sweetie Belle! That really does save a whole lot of time.

Do you suppose it might be possible to develop something that could do the reverse process? I know its not as straightforward as doing the opposite hex editing - but it would be super cool if it were possible to take PC chao and throw them back onto the GameCube. Maybe its not possible, but I know a few people who would definitely love something like that.
