How to have complicating saving in a horror game

[johndfg]

I'm creating a horror game, and I'm looking for scripts that when prompted to save, will automatically save over the previous save slot (warning the player and prompting an "are you sure" message.
I'm also looking to be able to automatically delete the save file when the player gets a game over.
Are there any published scripts that allow this? I can't seem to find any.
If not, is there any way for a non-programmer such as myself to make this, or is someone willing to script this for me?
