Sharp Shot is an odd yet simplistic game released in 1982 for the Intellivision. It features four minigames: Touchdown Passing, Space Gunner, Submarine, and Maze Shoot—each of which were likely old demos for NFL Football, Space Battle, Sea Battle, and AD&D: Cloudy Mountain, respectively.

The goal of each game is to shoot as many targets (or touchdowns) as you can in 60 seconds. Though it is a score-based game, time still comes to play in the TAS through luck manipulation at the start of each minigame and how quickly the game is switched after the timer runs out.

Objectives

Okay, so what exactly was the goal here?

There are four minigames, each of which can be selected at any time. To make this a complete submission, I do not switch minigames until the timer completes for each as this will effectively showcase all of the game's content.

Now, I aim for the maximum score in each minigame, but since the minigames are on a fixed timer, where does the speed challenge come from? Well, points can still be scored after the timer ends so it is preferrable to accumulate those last points right as the timer ticks to '0'. Additionally, some of the minigames (Submarine, most notably) have a delayed start for luck manipulation.

2 Players Only Space Gunner and Maze Shoot allow both players to control at the same time so I took full advantage of that during this TAS. I did not play Touchdown Passing and Submarine twice to give the second player a turn as that seemed redundant and would detract from the entertainment value of the run.

Touchdown Passing

The paths that the quarterback, receivers, and defenders run are all random. To score as many touchdowns as we can as quickly as possible, we need to manipulate RNG such that the quarterback and receivers quickly line up with each other, and the receivers don't run too far into the endzone as that will waste time. The player only controls when the football is thrown, and it always travels in a straight line.

It appears the minimum number of frames between touchdown passes is 220. I continually improved the longest segments until no faster variations were found. The final product has no duration between passes that exceeds 240 frames.

Space Gunner

Shoot as many spaceships as you can. There can be up to five ships on screen at once, and luck is a major consideration here. Where the ships fly in from is random and I generally manipulate such that no ships spawn from the upper left or fly down the middle, as these are the longest flight paths to the crosshairs. Both of these paths cross P1's crosshairs first, hence the heavy score bias towards P2. Ships only come from these directions in the final movie if manipulating otherwise was slower or not possible.

Explosion shrapnel is random and can blow up additional ships in the vicinity. I fire on the right frames to blow up as many additional ships as possible ouside the crosshairs. Only five ships can be on screen at once, so the sooner I can shoot every ship, the sooner more can spawn.

Submarine

New ships can spawn on the left or right side of the maps and have varying speeds on the paths they take. New ships are ideally spawned in the direction the submarine is headed so they will meet up the quickest. There are four submarines, so the faster you shoot a sub, the faster you will be able to shoot the one that respawns.

I waited 21 frames before switching to Submarine and 24 before starting to start spawn four ships on the left. Yeah, luck manipulation in this minigame is extremely tough, as you may have guessed by the odd, unoptimal timing of many of my shots. Only three torpedoes can be fired from the sub at once, adding to the madness.

Maze Shoot

The methodology here consisted mostly of shooting whichever enemy or groups of enemies took the least amount of time to shoot. I frequently go out of my way to shoot groups of enemies that are close together for a precise double or even the rare triple shot! The player cannot control where the arrows shoot from; only when they fire.

Totals

Game Score
Touchdown Passing 112
Space Gunner 68+113
Submarine 71
Maze Shoot 79+69
Total 512
I move on to the next minigame as soon as possible after the max score is reached for each. In Submarine, the final score is only on screen for one frame so it is barely perceptible. Score is tracked at Main RAM addresses 60 and 61 for P1 and P2, respectively.
