Help - Digimon World data squad fs.bin

[DaryuKien511]

Hello, I have been translating the game digimon world data squad to spanish, the game is giving me problems because I can not extract its font as it is in the fs.bin file, a file with proprietary format which I could only get some images that do not serve me with foremost linux, if you have any idea how to unpack it would help me a lot, thanks in advance

        public static Byte[] iDecrypt(Byte[] lpBuffer, UInt32 dwKey = 0x6E6B7270)
        {
            UInt32 dwMagic = BitConverter.ToUInt32(lpBuffer, 0);

            if (dwMagic == 0x53524944)
            {
                UInt16 wFlag1 = BitConverter.ToUInt16(lpBuffer, 8);
                UInt16 wFlag2 = BitConverter.ToUInt16(lpBuffer, 10);

                if (wFlag1 == 1 && (wFlag2 & 1) != 0)
                {
                    UInt16 wValue1 = BitConverter.ToUInt16(lpBuffer, 12);
                    UInt16 wValue2 = BitConverter.ToUInt16(lpBuffer, 14);

                    dwKey = (UInt32)(dwKey * (wValue1 ^ wValue2));
                    UInt32 dwSize = ((BitConverter.ToUInt32(lpBuffer, 4) + 3) >> 2) - 4;
                    Boolean dwRemaning = ((BitConverter.ToUInt32(lpBuffer, 4) + 3) >> 2) == 4;

                    if (!dwRemaning)
                    {
                        for (Int32 i = 16; i < dwSize * 4 + 16; i += 4)
                        {
                            UInt32 dwData = BitConverter.ToUInt32(lpBuffer, i);
                            dwData ^= dwKey;
                            dwKey = 5 * dwKey + 1;

                            lpBuffer[i + 0] = (Byte)dwData;
                            lpBuffer[i + 1] = (Byte)(dwData >> 8);
                            lpBuffer[i + 2] = (Byte)(dwData >> 16);
                            lpBuffer[i + 3] = (Byte)(dwData >> 24);
                        }
                    }
                }
            }

            return lpBuffer;
        }

FS.DIR is encrypted, so the code above will help to decrypt it. if someone wants to check it and help to reverse structure i also attached the decrypted file. Looks like strings is flipped... some examples

TOOR - must be ROOT

atad - data

retlif - filter

end etc.

 

Some correct paths

Thank you very much for the script, I will see if I can move forward with the translation, seriously thank you very much, I asked in many forums and nobody answered me.
