Legends of Troy

hi guys here is my save i got 2932 Kleo in hex 00000B74.

this game can be modded but i dont know how to pass the checksum.

hope anyone can do this

thx

Check is a CRC32 ran over 0 - (EOF - 4), written @ EOF - 4 (last four bytes) . Check is the same on all files (Profile, Settings, Scenario). Too bad this game isn't going to be released in NA, it looked semi-interesting..

Code:

---

    Sub FixTroyCRC(ByVal File As String)
        Dim IO As New System.IO.FileStream(File, System.IO.FileMode.Open, System.IO.FileAccess.ReadWrite)
        Dim Buffer((IO.Length - 4) - 1) As Byte
        IO.Read(Buffer, 0, (IO.Length - 4))
        IO.Write(SmallCRC32.Compute(Buffer), (IO.Length - 4), 4)
        IO.Flush() : IO.Close()
    End Sub


    Function ValidateTroyCRC(ByVal File As String) As Boolean
        Dim IO As New System.IO.FileStream(File, System.IO.FileMode.Open, System.IO.FileAccess.Read)
        Dim Buffer((IO.Length - 4) - 1) As Byte
        IO.Read(Buffer, 0, (IO.Length - 4))
        Dim Calc() As Byte = SmallCRC32.Compute(Buffer)
        Dim Crnt(4 - 1) As Byte
        IO.Read(Crnt, 0, 4)
        IO.Close()
        Return CBool(BitConverter.ToString(Calc, 0) = BitConverter.ToString(Crnt, 0))
    End Function
