I am currently making a game, but have still to implement some sort of save game system... The game loads all of its data in from a database with several tables, but sets variables during play as well...

Ideally, I want four save slots, so I thought of choosing a save slot before play starts, copying the master db file to the folder, ie save1... and playing from there... but how would I save what data was stored in the variables when the player wants to save? using an .ini file? i've never had to do this before... can anyone advise on this?

cheers
