Hi,

We are doing an uncensored version of Skies of Arcadia, instead PAL version (from japanese_cake patch VGA release) with JAP skins that have be change like this one :

We are going on well, but I would like to use this project for trying to import some models and skins from gamecube version like Vyse and Alfonso :

so I had a look on datas. There are stored identically but as we know the gamecube version is quite compress and for a file with textures like player.MLD (we can find Vyse textures here), I have this :
ibb.co

ibb.co ibb.co

All files are compresses by the same way.
Do you have any idea how I could I unzip the files ?

May you can suggest me a gamecube forum where I could find some help please ?
 
Thanks a lot it works well but only for textures (that's already very good).
I'm looking for model too.

But I can work now :)
 
The first disc is almost done, here a list of modifications :
Dyne now has a permanent Cigar, except for one scene.
Willy, Gilder's parrot also has a cigar permanently.
Gilder has a victory pose where he smokes a cigar.
A pnj has been added on Sailors' Island, it is a drunken sailor. His dialogues are translated.
Bellena has a sexier/lighter outfit in Maramba, identical to the artworks.
Vigoro has a lighter outfit in the scene where he is a little bit forcing on Aika, he also keeps this outfit in combat when we are facing him.

Of course, the game is VGA compatible thanks to Japanese Cake :) and since this is the pal version it is translated in English, Fr and probably other languages.

The changes on the CD2 should be identical. Some blood will just be added in a scene with Ramirez.


I'm still looking for textures improvements and models, no time to look much but I go on.
 
There is one difficult file to uncensored...
It's the ramirez's blood at 1min11s :



It's not present in PAL version :

I need help :

The file is the ME131I.SCT
Two issues : taking 4 langages and inject instead of jap and add others langages.
Import the blood animations in PAL version.

The first word of 4 bytes is not to be modified, it is the same for both versions, for me it is the name of the file :

ibb.co

ME131-I-SCT

Image ME131-I-SCT hosted in ImgBB
ibb.co ibb.co

The second word of 4 bytes, I don't know what it is, I was thinking of a pointer but the file is smaller...
Both are to be tested...
ibb.co

ME131-I-2-SCT

Image ME131-I-2-SCT hosted in ImgBB
ibb.co ibb.co

The third word, I don't know what it is either... I was thinking about the total of the instructions of the "loop" but it doesn't match ...
ibb.co

ME131-I-SCT

Image ME131-I-SCT hosted in ImgBB
ibb.co ibb.co

After that we have the list of instructions and image files or pick. and just before the pointer.
In all this list there are 7 differences in the first place the languages :
ibb.co

ME131-I-5-SCT

Image ME131-I-5-SCT hosted in ImgBB
ibb.co ibb.co

3 more langages more than jap version in PAL :
In the JAP file there is only one command "eve_115", in the PAL file there is in 4 first of all "eve_115" which must correspond to english then we have "eve_115s" for spanish then "eve_115f" for french and finally eve_115g for german.
Two dialogs and 6 "eve" instructions in PAL so I'm pretty is sure dialog.

The seventh difference is going to be an extra command on the JAP file at address 0x840 the LIG_123b_def and I think the blood is called there...
ibb.co

ME131-I-6-SCT

Image ME131-I-6-SCT hosted in ImgBB
ibb.co ibb.co

If I import it in PAL I must fix all pointers above 0x0xC74 -> LIG_123b_def

But In fisrt in your opinion what are the datas at the beginning of the file ?
Do you have any idea please ?
 
Skies of Arcadia Legends files are AKLZ encrypted, use this command line tool to decrypt them (made by ADnova): https://cdn.discordapp.com/attachments/581612678670188565/772869821326950450/aklz.exe

To decompress a file:
aklz -d inputFileName.sct -o outputFileName.sct

-d for decompress
-o for output

Also, here are some findings about the .SCT structure from AdituV:

Header: 12 bytes
+0x8: number of script sections

Section headers: 20 bytes each, starting at 0xC
+0x0: offset in the data block for the section's data
+0x4: name of section/function/something
 
Oh thank you very much :-D
due to covid, I must have a break but thanks to you, I have more informations to go on.

Click to expand...

[EDIT] : C0 is the good number of script version for PAL so yes thanks to you, "+0x8: number of script sections" :-)

Second thing at offset 0x5 and 0x6 PAL and JAP have different byte, do you know what those bytes are ?

Thanks for gamecube decompress tool ! It works like a charm :) Hope I'll be able to learn more with it.

We are testing ME131I.SCT file with Ramirez's blood, but I think I have finally finish to patch it.
I explain here how I've done soon.

Thanks to r3nz0, to help me :-)

Hope the release comes soon.
 
How I've done to patch the ME131I.SCT file.

The goal was to import in PAL version with 4 langages, Ramirez's Blood.
It was easier to choose this way, than import 4 langages in jap version due to text encoding issue.
Thanks to all people who help me :-)

How a skies of arcadia file is managed :
1) The first word of 4 bytes is not to be modified, it is the same for both versions, for me it is the name of the file :
ibb.co

ME131-I-SCT

Image ME131-I-SCT hosted in ImgBB
ibb.co ibb.co

The second word of 4 bytes, I don't know what it is, I was thinking of a pointer or the file size check but the file is smaller...
fortunately no need to change this one :-)
ibb.co

ME131-I-2-SCT

ibb.co ibb.co

The third word is the number of instructions, I add one instruction (lig123bdef), it's not the Ramirez's blood but it was in more in the jap version so I added it.
I patch this one from 0xC0 to 0xC1 :
ibb.co

Skies-of-arcadia-2

Image Skies-of-arcadia-2 hosted in ImgBB
ibb.co ibb.co

after that you have the instruction list starting at adress 0xC :
each instruction is managed on 0x14 bytes :
For example with the fourth called "l15cut1" :
ibb.co

Skies-of-arcadia-3

Image Skies-of-arcadia-3 hosted in ImgBB
ibb.co ibb.co
4 firsts bytes are the pointer, the beginning adress of instruction :
ibb.co

Skies-of-arcadia-4

Image Skies-of-arcadia-4 hosted in ImgBB
ibb.co ibb.co
the rest is for the name :
ibb.co

Skies-of-arcadia-5

Image Skies-of-arcadia-5 hosted in ImgBB
ibb.co ibb.co
In order to find the beginning of an instruction, you have to add to this pointer the list of instruction size !
For example :
l15cut1 (instruction number 4) the pointer is 0x498 in big endian, the list length in the patch file is 0xF20 (0xC1 * 0x14 + 0xC of file head length)
so to find the beginning of the instruction 0x498 + 0xF20 = 0x13B8
Each instruction starts by 0x09 00 00 00 :
ibb.co

Skies-of-arcadia-6

ibb.co ibb.co

After the listing you have the code, at the end you can find a new listing of files that are called.

2) In first I compare the size of each instruction doing the difference length with the next pointer and the actual of the instruction :
example for init the first one :
0xC4 - 0x00 = 0xC4


I did it with US and JAP, because there are only one langage both.
i found that instructions : l18cut10, l18cut11, l18cut13 are bigger in jap version, and do the same size in US and PAL versions.
I imported the JAP datas in more in PAL version, simply by doing a copy and an insert.
I used the free software "beyond compare" :
ibb.co

Skies-of-arcadia-7

ibb.co ibb.co

After that I have to patch the pointers of listing due to new datas.
add the datas adds to next pointers of l18cut10, l18cut11, l18cut13 and lig_13b_def until the end of listing.

3)
If you run the game with the file, you'll have a black screen...
It's because the pointers inside the code are not good anymore.
Each pointer have the format 0xXX XX 00 00, or 0xXX XX 01 00
Thanks to "beyond compare" there are now in red comparing PAL patch and JAP version in the code :-)

The "small" pointers are not to patch because the code is not modified next of them.
There are still in black in beyond compare, but I checked them too in order to do not mistakes.
ibb.co

Skies-of-arcadia-8

Last thing to understand a pointer inside the code work by adding to his own adress to its number
for example with the one of the last screen capture :
0x00 01 31 B8 at adress 0x45AC

for locate the target :
0x1 31 B8 + 0x45AC = 0x1 7764

this one one target an other instruction :
ibb.co

Skies-of-arcadia-9

Last thing to care of is the text there are 4 pointers for each text than Jap have only one.
After a lot of patience the patch is done :-D

So to finish the uncensored version, there is a last little issue with Gilder attack.
But we can consider is now good.
With this knowedge, I don't know if it's possible to import the Gamecube addings, but it can help for sure.
