Car Racing Game in x86 Assembly

This is a simple car racing game implemented in x86 Assembly for DOSBox. The project demonstrates graphics programming, keyboard input handling, animation, collision detection, and basic multitasking for background music. The game is developed in multiple phases to progressively add features, presenting both programming logic and presentation skills.
