Well for the moment I may have an idea of what to do, thanks very much, but didn't you mean to write "N+1" frame rather than "N+4"? Too bad I don't know any assembly languages. Hopefully I won't have to go through all that trouble (though I have a second project going on too, which I will get back on working with soon. For the interested; http://forums.qhimm.com/index.php?topic=8597.msg107402#msg107402 ) Edit: Let's see if I understand this right... If I keep trying to roll the dice in the aforementioned manner, I will find a sequence, right? When I get back to the beginning of the sequence, then I find the exact probabilities? (can't find anything in FAQ that helps me here) This is all assuming it is only time/frame based.

I don't want to just pull a good dice roll. I am probably asking about reverse-engineering the number generator. So say rolling the dice 10000 times and calculating the approximate likelihood of each drop is NOT what I want to do. I couldn't imagine how frame advance would ever help me go around this problem of approximation, which is why I asked. Seems like it can't. Guess I have to reverse-engineer (no idea where to start though). I don't understand this part thought

Can Frame Advance be used to figure out the exact likelihood of outcomes?
You can try a random event on every possible RNG state and record the probabilities. You'd use frame advance to make sure your inputs are precise.
Random Number Generator state? I'm not sure how this differs from just pulling the lever 10000 times without frame advance. Note: Would also be nice to know the probabilty of Cid or Tifa asking Cloud to Snowboard or play the Chocobo Races.

I recently started using the PCSX emulator, for I had heard that (maybe) "Frame Advance" function can be used to help determine the exact probability of certain outcomes. Here I think about the dropped items, or lackthereof, with the left and right Wonder Catcher in Gold Saucer. Questions: Assuming that the probability is frame-dependant, how do I go about this? If it is not frame dependant, what else can I do to figure this out? Note: Equally I want to figure out the probability of Cloud saying "...Ugh." after a Speed Square run.
