Help with save Battlefield Bad Co2

[CarnageSP]

The game and the Battlefield Bad Company 2, with a hex editor, I tried to find the numbers of weapons ammo I'm using and found these codes.

Put to the test when making the changes do not appear ie remains as original, the Hex editor to review the changes and return to the default save 1mb increases in the original size, and that 1,05Mb.

Got it, it follows the same line of Rainbow Six Vegas, all changes made in error or corrupted file changes back to the default.
Do not quite understand how the checksum works of saves, would be the base of the same roms?
Mess with Romhack, the checksum of the roms would be checking the data file with the saves follows is the same as seen in the header file that every load is changed some information.

PS:
Sorry for my English, if you do not understand something please try to explain better.

I looked into the .xex and found the checksum routines. The game uses the EA checksum and also a custom one.
I'll rewrite it in C# and upload the code into my security archive. Then you can make an editor for the game. ;)

[Philymaster]

So finally ... :D
The code for all checksums is in my security archive now: http://www.360haven.com/forums/threa...808#post278808

Also modded for a test unlimited ammo (at least 999999 bullets), works great and makes fun without reload. :D
