F-Zero All Leagues (Master Difficulty)

I am very proud to present the very first Full TAS of F-Zero on Master Difficulty. This has been a project that took slightly over 5 years to see finished. It has come with much pain and suffering. Quite literally, my blood, sweat, and tears have been tried tremendously.
This TASing en devour started with asking a question, back in January 2017..."Why hasn't this game been TASed?". Now I know why. After observing a number of attempts, from others, I've noticed dead silence after a few months. For me, it was too exhausting to reach of level of optimization that would satisfy me. My original efforts were hard enough on me that my eyesight and sleep were affected dramatically. After my Queen League submission, I found myself too exhausted to continue on, and walked away. It was at that point, i realized that this game MUST be BOTed...yet, I had no knowledge on where to start or how to accomplish it.
After a year of BOTing Tetris 2, my experience had increased enough that I was finally able to attempt a BOT for F-Zero. It was when Aran;Jaeger approached me about a community member stating "We need more F-Zero TASing", was I able to step back into this and finally understand how to put a theory to the test. The result... A BOT was created.
For the past 15 months...F-zero has dominated my attention. The results...complete destruction of all know times produced by my previous attempts, and that of two amazing TASers...Inichi, and Miki Higashi (IE IDK). Both of these TASers were incredibly hard to beat. I knew up front, that beating them would require the use of a BOT...which ended up making a very successful run.
Here is the BOT in action. This recording was done with display on, so that you can see what is occurring. The actual speed of BOTing reached over 300fps. Also, part of this video shows the TASStudio manager and the inputs that are changing. The Lua script console starts to show improvements near the end of this clip.

Two Encodes

When I came back, to complete what I started, I made a hard decision over RTA and IGT runs. Because I can't leave behind any frames, and the fact that F-zero League racers use 2nd place to skip cut-scene times, I continue my same strategy of coming in 2nd place to reduce the cut-scene time between tracks. So, instead of giving some viewers the same disappointment, I decided to surprise both types of viewers with two encodes. One that reflects the true run, from submitted inputs (RTA), and another that comprises of spliced, 1st place segments (which was put together in a frame perfect movie). Even thought the IGT version is not real, it is my hopes that it will satisfy the curiosity of seeing the best track times possible. Here is an encode that has been "Spliced" for IGT 1st place finishes. It is based off of the submitted inputs, when ran all the way through for 1st place. Because of this, the TAS cannot be realigned to have an IGT version without redoing the entire inputs again.

Terminology

  • Golden Fox - The fastest accelerating vehicle on the circuit.
  • Blue Falcon - The second fastest accelerating vehicle on the circuit, with a little more top speed than the Golden Fox.
  • Wild Goose - The third fastest accelerating vehicle, with higher top speed than the blue Falcon.
  • Fire Stingray (Car of Choice for this TAS) - The slowest accelerating vehicle, with the highest top speed of the available cars for racing.
  • Brown Cars - Also known as CPU RNG obstacles. These cars can be of massive aggravation and costly of lap times. Usually, they cost anywhere from 1/4 of frame to 2 frames to avoid them. In one situation, 6 frames were lost... but recovered by reTASing earlier parts to avoid RNG for that terrible situation.
  • Super Jet - On the completion of each lap, the driver is reward a super jet, which when used...moves the car from its capped speed to 562 as the highest. It cycles from 562 to 478 for 4.25 seconds.
  • Brake Tapping - Refers to a technique, for when super jets are used, to gain greater speed by manually cycling the speed back up to 562 as fast as possible. This is done by braking at a certain speed to eliminate the lower part of the super jet speed cycle so that your car is running at speeds on the top end more. The result, is about 4 frames cut per lap.
  • Blast Tapping - Refers to when the accelerator is released to allow your car to make tighter turns. This coincides with a slippage value and prevents it from reaching the maximum value. Basically, it keeps your car stuck to the ground and prevents you from loosing traction and thus keeping your speed up.
  • Wall Tapping - This is a term that I came up with, that is used to help cycle the super jet speed correctly so that the timing is fixed to maximize the use for when traversing dirt of borders.
  • Practice Mode - The game offers a player the ability to race a single track. This usually is accompanied by the selection of an opponent. The choice of your opponent can determine greater speeds...in most cases, Golden Fox is used to get the highest speed boost and used most often.
  • Grand Prix Mode - The game is normally played with through one of three leagues...known as Knight, Queen, and King leagues. This TAS features the first league.

Tools Used

  • Lua Script:
The main BOT (responsible to automating the testing inputs and their affect on any distance gained) HUD, for determining position and progress Frame-by-Frame data builder for use with the HUD
  • RAM Watch (The need for super jet timing, pixel/sub-pixel placement, speed changes, and HP)
  • Bizhawk 2.6.1

Master Difficulty

This TAS requires the unlocking of Master, which means that all leagues must be beaten on Expert mode. I have uploaded an SRAM verification run to do so. https://tasvideos.org/UserFiles/Info/637836643457140766

Track/Lap Improvements

Memory: well I guess I won't be the first to finish a full game f-zero tas after all but I think that's going to be ok. Claiming for judgment.
Memory: I'm very happy to finally see this TAS actually exist. Given the trials and tribulations the author told me about, I was convinced he would never want to look at F-Zero again, let alone bot it. Well done! Since this does use SRAM, it's going to Moons.
Note to whoever claims this for publishing, nymx told me he would like to have an ingame time focused encode created as well. Get in contact with him for the specifics on how to do that.
