Could someone point me in the way of a guide for rng manipulation and the step route for the NES version? I've only found a few 3 hour Youtube videos for the route and documents that don't seem to work any more. I think I've figured out that some of it is reset when you turn the console off then on.

I do know that in order to reset the RNG you have to beat the game and let all of the credits play. if you don't none of the RNG manipulation would work properly.
