Vectrex machine emulation
The emulator executes the cartridge and BIOS in the browser, including the Motorola 6809-era machine logic, vector drawing path, sound generation, timing, and controller input needed by the embedded library.

Vectrex emulator guide: play Vectrex games online
Vectrexia is a browser-based Vectrex emulator that starts instantly, runs BUGS by Sean Findley, and links every canonical game to researched history, programmer credits, gameplay background, and named research and preservation sources.
The machine
What makes the Vectrex different?
The Vectrex is a self-contained vector-display console released in the early 1980s. Instead of drawing an image as a grid of colored pixels, its display steers an electron beam between coordinates to form bright points and lines. That direct vector presentation gives games such as Mine Storm, Armor Attack, and Star Castle their sharp wireframe look.
Commercial cartridges commonly used translucent screen overlays to add color, artwork, and interface labels. The system also supported unusual accessories, including a light pen and a stereoscopic 3-D Imager. Vectrexia runs the cartridge software in a modern browser, while clearly noting where a physical accessory or original overlay changes the experience.
Inside Vectrexia
How the browser Vectrex emulator works
WebGPU-first vector rendering
WebGPU is the preferred renderer. WebGL2 and Canvas2D fallbacks keep the emulator playable on browsers or devices without WebGPU, while display controls tune beam width, persistence, bloom, scanlines, mask, tint, and brightness.
Keyboard and controller input
On phones and tablets, an illuminated on-screen analog thumbstick and four multi-touch action buttons sit directly beneath the Vectrex. Arrow keys or WASD control movement on desktop, Z, X, C, and V map to buttons 1–4, and compatible USB or Bluetooth gamepads can use the left stick, D-pad, and standard face buttons.
Embedded, verified cartridges
Built-in ROM files are compiled into the ASP.NET Core application and verified against cataloged byte lengths and SHA-256 hashes before play. Local ROMs can also be opened without uploading them to the server.
Beyond a ROM list
Research-backed Vectrex game pages
Each canonical game page now combines the playable cartridge with unique historical and editorial information: release context, programmer and designer credits when verifiable, publisher, genre, player count, gameplay background, variant notes, controller help, related titles, and named research sources.

Research method: Programmer and release credits are based primarily on the Vectrex Game Database, Vectrex developer recollections, manuals, preservation catalogs, and title-specific references. Unknown or conflicting facts are labeled instead of guessed.
Who · how · why
How the Vectrex game research was created
Who: The research record is compiled for Vectrexia. Individual programmer and designer credits are attributed to their named sources; Vectrexia does not claim authorship of the original games or historical records.
How: Programmer and release credits are based primarily on the Vectrex Game Database, Vectrex developer recollections, manuals, preservation catalogs, and title-specific references. Unknown or conflicting facts are labeled instead of guessed. Each title is marked as verified, partial, or catalog-based. Conflicting dates, uncertain credits, prototypes, and alternate names are described rather than silently resolved.
Why: The goal is to make the playable emulator useful as a preservation and learning resource, not merely a list of ROM filenames. Visitors should be able to play a title, understand where it came from, see who made it when that is documented, and follow the sources.
Accuracy notes
Overlays, 3-D games, and the light pen
A browser can run the cartridge code without reproducing every physical component of the original setup. Overlay art may be loaded separately. For 3-D Crazy Coaster, 3-D Mine Storm, and 3-D Narrow Escape, Vectrexia models the motor PWM, wheel-index sensor, and VIA synchronization needed by the cartridges; the original spinning color wheel and stereoscopic separation still require compatible physical hardware.
Light-pen titles can also require interaction patterns beyond a mouse or standard gamepad. Relevant title pages call out these limitations instead of implying that every original accessory is fully emulated.
Common questions
Vectrex emulator questions
Can I play Vectrex games in a browser?
Yes. Open Vectrexia, let the embedded BIOS and startup cartridge load, and play with a keyboard or compatible controller. The Games and Demos sections provide stable URLs for individual titles.
Does the emulator require WebGPU?
No. WebGPU is preferred, but Vectrexia includes WebGL2 and Canvas2D fallback renderers.
Can I use a joystick or gamepad?
Yes. Connect a USB or Bluetooth controller, then press a button once so the browser exposes it to the page. The left stick and D-pad handle movement, and face buttons map to Vectrex buttons 1–4.
Are programmer credits and game histories verified?
Every canonical game page has a researched record with named sources. When surviving records conflict or do not identify a programmer, the page says so rather than inventing a credit.
