[REQ] Halo Spartan Assault Checksum Help

[Idlehands88]

Hey guys, I was wondering if anyone could look into finding out how to fix the Checksum for the XBLA game, Halo: Spartan Assault.

At 0x18 there is an Int64 value that changes everytime you reload the save and go back into Hex Workshop to look for changes. I believe the Checksum is either TWO Int32 Checksums or ONE Int64 Checksum...

I have included a RAR file that contains 2 Saves and the Default.xex. For the saves, all I did was change the Music Volume to make the save different, nothing else was done on them.

Please help me

I tried CRC32 and MD5, but I didn't get any results with it. I need to know the start and end of the Checksum's Calculations.
