Password for every save slots

Is there a script that will enable to have a password for save slots? Coz i wanna create a game that will secure the file to be overwritten by someone that will gonna ruin your game. TIA   :D

If you're concerned about your savegame, the easiest way to handle it is to back up the savegame on a USB stick and take it with you.  Or put a copy on Dropbox/Google Drive/etc.  This makes it a lot more likely you'll have a backup copy of your savegame.

Really, if someone has physical access to the machine, and can run the game and save their game in progress, there's no practical way to stop them from ruining your game, whether it's by a malicious hack, or accidental "saved my game in the wrong save slot"

If it's an accidental thing, you could try creating another non-privileged user account and letting that person access the game from there.  Since VX Ace writes to the local user's Documents folder, they won't overwrite your saves, even if they use the same save slot.

So, basically, backup your saves and create a separate user account for them, and that should do the trick.
