Problems Extracting Data.xp3 of Swansong

Hello, I wanted to extract scripts from Swansong and thinking of slowly translating the game.
So, I downloaded Insani's xp3 tools and using xp3-extract.exe, i extracted the data.xp3.
But when I open the file (of course choosing japanese encoding) but it gives me some alien symbols only.
So I thought maybe I did something wrong while extracting, I tried to extract again and found the message saying,

"WARNING: File is encrypted but no known encryption type specified
Known types include: fate_trial, fate_full
Checksum error, but continuing..."

So I tried the two types above by adding -fate_trial, -fate_full, or -fate and tried but all three times gave me the same message.

Please help me how to extract files from data.xp3 of Swansong. Thank you.

Use this instead.

Thank you for the advice.

I downloaded kikiriki.exe and madCHook.dll and tried to unpack data.xp3 but it gives me the error message "EPrivilege."

I placed the kikiriki.exe and madCHook.dll in the game folder and followed the instructions on the webstie but it gives the error message I mentioned above. Is it because the file is encrypted? Is there any other program or special command to unpack this game ?

Thank you.

use crass for encrypted files

Thank you very much!

I guess I did not search the Internet thoroughly. Still, it took me few tries to figure out that I need parameter. But it worked for the encrypted file!
