This might be a flawed approach, depending on how the game generates its random numbers. If they actually do a random number generation at the time of the 'dice' roll, then fine. But many games use a pregenerated random string of numbers so reloading won't necessarily affect a 'dice' roll.
This game does not employ a fixed random seed. So his method would work. It'll be extremely time-consuming and boring, but it'll work.
