It's not even a true brute-force (which would systematically and exhaustively try
everything), all it does is randomly-by-weight throw out inputs during the specified number of frames starting from the save state.
(Incidentally, using these settings for FlapPing under AtariHawk is amusing to watch)
The first thing you need to do is set a starting save-state in the game. Basic Bot defaults to State 0, but I prefer using State 1 simply because that's an easier hotkey for me to hit. At this time, it has to be a numbered state.
The second thing you need to do is set control weight. The higher the number, the more likely that any given frame will be sent that keypress.
(Unlike my PRNG lua script, the keypresses are not mutually exclusive under Basic Bot, so you can get stuff like EVERYTHING ALL AT ONCE. At the same time, there's always the chance that no input at all will be sent on a given frame)
The third thing you need is memory addresses to track. Basically, these serve as goals for Basic Bot to look at. These values determine which attempt is retained as "best".
The fourth and final thing you need is a duration. Basic Bot is capped at 999 frame segments... just long enough to almost play a complete game of FlapPing. Once the bot runs for this number of frames, it'll check the memory addresses. If the conditions are satisfied, that attempt will become "best" and be stored in the Best field. If it doesn't satisfy the conditions, the attempt is more-or-less discarded.
