Al Unser Jr. Turbo Racing NES

Al Unser Jr.'s Turbo Racing is a racing video game for the Nintendo Entertainment System console released in 1990. It is an adaption of the 1989 Japanese-market Famicom game World Grand Prix - Pole to Finish (ワールドグランプリ ポールトゥフィニッシュ), with the most notable changes being the addition of Unser as an in-game coach, the number of laps, sound and interface design. Therefore, the game remains based on the Formula 1 World Championship, despite Unser having never competed in it. This game features a season mode and two time trial modes. In season mode the player uses either Al Unser Jr. or make their own driver.
Versions released outside North America were simply titled Turbo Racing with all references to Unser removed, due to the relative obscurity of CART and Unser outside of North America.
Gameplay
The game is a racing video game. The player directs the car using the D-pad, accelerating with A and braking with B. The gauges, speed, and several other things can be seen at the bottom of the screen. Turbo boosts can be used by the player when necessary, but must be refuelled when empty. Hazards such as signposts and other cars must be avoided. Qualifying is held prior to each race, but is difficult because only one lap is given.
Due to the limitations of the NES, curves appear to come out of nowhere, making turning unusually difficult.
