The Vectrex was a unique home video game console released in 1982 by General Consumer Electronics (later acquired by Milton Bradley). Unlike any other console of its era, the Vectrex had its own built-in vector CRT monitor — the same technology used in arcade classics like Asteroids and Tempest.

Vector displays draw images using electron beams tracing lines directly on the phosphor screen, creating bright, sharp, ghostly graphics with a characteristic glow and afterimage persistence.

This emulator simulates the Vectrex experience with a simplified 6502-inspired CPU core executing bytecode programs, a vector graphics engine with authentic phosphor persistence, bloom, and CRT effects.

Controls: Arrow keys/WASD = D-Pad, Z/X/C/V = Buttons 1-4, Space = Start, P = Pause, D = Debug, R = Reset, Esc = Settings

The Vectrex used a Motorola 6809 CPU and an AY-3-8910 PSG sound chip. This simulator approximates the experience with modern web technologies.
