Hi everyone,

I'm trying to explore and extract content from the .dat files used in an old MMORPG called "Istanbul Kıyamet Vakti" (released around 2006–2008), which was developed using the Actor Game Engine. Based on the filenames, I believe these .dat files might contain things like music playlists, animations, and similar in-game data. Here are all the .dat files I have at the moment.

I'd really appreciate any tips or guidance.

Thanks in advance!

.dat files look compressed so you'll need to find out which compression type was used by Actor Game Engine.

        public static Byte[] iDecrypt(Byte[] lpBuffer)
        {
            Byte bTemp = lpBuffer[lpBuffer.Length - 1];

            for (Int32 i = 0; i < lpBuffer.Length; i++)
            {
                bTemp = (Byte)(lpBuffer[i] ^ (87 * i + 85));
                lpBuffer[i] = (Byte)(bTemp ^ 0xAA);
            }

            return lpBuffer;
        }

Just drag and drop those dat files🙂 IKV.DatDecryptor.zip

@Ekey, thanks!

@all: the decrypted animation.dat results in an xml file, which doesn't contain animation keys but animation parameters in "clip" lines (which seem to be some kind of frames):
