ROM Hack What is a secure value?

[Ev1l0rd]

So um... yeah. What is it? When I import saves I always remove it (because I read somewhere that you have to do it), but what exactly is it?

 

[Games&Stuff]

Some games don't want you to let you restore saves (this can include all unlocked things and stuff), so they use secure values. It's a protection.

 

[KazoWAR]

Games that use this feature. Everytime the game is saved a random number is generated and stored in both the save file and in NAND. The game checks if these two numbers match when it is loading the save data. If they mismatches, the game will reject the save data. Like Games&Stuff said. It is to prevent people from restoring old savedata. Like say for pokemon. Tradeing a pokemon to a 3rd party then restorong old save to basicly clone the pokemon.
