Introduction

This is a TAS of Hyperchase for the Vectrex, the only vector-based console ever released! In this game, you play as a formula one racecar driver, and your goal is to make it to the finish line as fast as possible.

Version

This is played on BizHawk 2.9.0, and it uses the USA release of Hyperchase.

Controls

Vectrex controllers consist of a joystick and 4 buttons which are numbered 1-4. Left and Right on the joystick move your car to the left and right around obstacles. Up and Down on the joystick do nothing. Pressing the 1 button makes your car shift to a higher gear. Pressing the 2 button makes your car shift to a lower gear. Pressing the 3 button makes your car brake. Lastly, pressing the 4 button makes your car speed up.
Based on all of this, the only buttons that we press in this TAS are Left + Right on the joystick, the 1 button to shift to a higher gear, and the 4 button to speed up.

Strategy

We start in 1st gear, and there are a maximum of 4 gears for the car. Basically, you want to press 1 to shift to a higher gear at the perfect time. Too early, and it will take you a longer amount of time to reach the same speed. If you wait too late, then you will also lose time from having waited. In this case, I just used trial and error to find the fastest 3 places to shift gears. (from 1 to 2, from 2 to 3, and from 3 to 4).
Note that the screen-scroll speed is stored at address 0X9D (this is the same as your car's speed). This value starts at 0, and goes up to a maximum of 15 when you reach the highest speed in gear 4.
Once we reach top speed (which happens in the first 5 seconds of the race), we just need to dodge cars and complete all turns until we reach the finish line.

End Goal

My goal for this TAS was to finish with the fastest in-game time. In the end, my final time was 96.6 seconds (the fastest claimed human time for this game is 100.1 seconds). This is also why I end input early - since holding the 4 button for the final 1/2 second of the race doesn't get you to the finish-line any faster (it takes like 1/2 a second before you go from 15 speed to 14 speed, which is why this works). This also resulted in the same (fastest) real-time ending to the game, as well.

Final Thoughts

There's a lot of cool Vectrex games out there, and there's only 29 total Vectrex games that were officially released - which makes me surprised that 2 years later only one has been TASed. People should look into TASing more of the remaining games!
Anyways, I hope you enjoy this quick TAS!

nymx: Claiming for judging.
nymx: Well, this is a straight forward game. The TAS just needs to stay alive and fast as possible to be the fastest. Ending input is a plus, in this case. Great job.
Accepting to "Standard" for publication.
nymx: Missed an update for a faster movie, by ending input earlier by 12 frames. Movie sync and submission is still ready for publication.

Any suggestions?

This video provides a review of every official Vectrex game in alphabetical order, in about 20 minutes: https://www.youtube.com/watch?v=AKf-k2IjUOo&ab_channel=FrameRater I'm planning to TAS Cosmic Chasm next, myself. Some other games from this list that people could try TASing are: 1. AnimAction (you can draw things and make them move across screen - a great game for a TAS play-around by someone artistic - if you can get the lightpen to work with TASes of the game) 2. Bedlam (Flying around space and shooting the walls to expand them. may or may not be a definite ending to this game, though). 3. Berzerk (also not sure if this game has a definite end point/max score. Similar to the version that exists for Arcade/Atari2600 where you shoot all enemies in a room). 4. Blitz! Action Football (now that the triviality requirement for TASes is removed, this could be TASed). 5. Clean Sweep (PacMan but with Vaccum Cleaners and Money - what more could you possibly want?!?!?) 6. Heads Up Action Soccer (could make for a funny meme TAS, but other than that, would be kind of bad to TAS). 7. Minestorm (like Asteroids, except It crashes at level 13, so you could consider that the ending).

Hello there, I made a movie back in late 2020 of the game which is 60 frames faster than this submission with the same IGT found here: User movie #638257216678082214. The movie was made on 2.5.2 so the SHA1 seems to not match but it is the same ROM used in this submission. I've never submitted it because I was struggling with different inputs on the TAS that led to a slower time, I had hypothesis but I needed to find the RAM value of the position of the car to understand but never quite understood back in the day how to find this value if it exists. That's why I let it on my computer and never touched it since. I also started a TAS of Bedlam but never finished a complete version.

I changed the end of my TAS to produce this movie: https://tasvideos.org/UserFiles/Info/638257591633501722 This movie has a marginally faster real-time ending compared to your TAS, which it does by just ending input early (it also has the "End" screen appear 12 frames sooner than in your TAS). Regardless, it has the same in-game-time...

That is a pretty unique looking older game. I had heard of this Vectrex years ago and it is cool to see a tas of one. Yes vote.
