Legends of Troy

[MBRKiNG]

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..

IO.Write(SmallCRC32.Compute(Buffer), (IO.Length - 4), 4)
IO.Flush() : IO.Close()
