I already try with cvm2iso, but it doesn?t pop in the files inside from the ISO, i read in other threads i was need to remove the header with 0x1800. I don?t know how to do that, i try with HxD but i can?t make sure what it is the right code. I try to remove the CHMV as value 00. So i need help here.
The cvm2iso it should already break the protection, but it seems it does more then convert the ISO even the UltraISO can?t read it.
The CVM tool i can?t find no tutorials or even one video to show how to do it on Windows.

I found the password to be the same to all as cc2fuku.

Here's the protected file i really wanna get the textures here: https://easyupload.io/vau9cz

If you wanna help me and send me the correct ISO will be a great pleasure.

Code on HxD inside.

If you ran the cvm_tool without the commandline with Command Prompt, it will explain the needed parameters you need to input. To extract the CVM to ISO, the command you want use is the split ones:

Code:

split [-p ]   []  Extract ISO file from a ROFS volume

So run the cvm_tool like this:

Code:

cvm_tool split -p cc2fuku DATA.CVM DATA.ISO

If UltraISO cannot open the resulting ISO file, try opening it with 7-Zip instead.

Done, but appears bad decryption key? No ISO as been done.

That means the password is incorrect. You'll have to find it again in the game's executable (Should be something named SLPM/SLPS or SLES).
Or you can sent that file here. Hopefully this isn't like the Virtual-On Marz where it doesn't store the password anywhere.

Done.

Any clues? I try to search over the SLES using HxD file but all of them appears a error.

Not yet, unfortunately. Give me some more time.
EDIT: Found the password, it was:

Code:

m   j  rr

I forgot to tell you that you must enter the password parameter with "" since it contains white spaces so:

Code:

cvm_tool split -p "m   j  rr" DATA.CVM DATA.ISO

Thank you now works.
Let's see if open the files.

Edit.

It's working fine!
I think you can find the other game you tell before, we need to be focused on that. Good Luck!

Now the logos i want to rip off are using .SVM File.
If someone can help me to open this.
I found less information always tells me it opens with openoffice, but only appears text and no textures.

Probably some SEGA internal formats. I'm not sure if these have been cracked open yet, but it's likely someone who has decomped SEGA stuff would know things.
