Bruteforce Save Data 1.4.2 updated 2012-12-27!
It's a frontend for flatz save data tools 0.2.3. It finds the keys of several games in seconds and let you resign your saved games.
Get from here
Needs a MSVBVM50.DLL to work correctly
I'm trying figure how to use this correctly,and will be testing now
Its a shame these keys are missing
