Vectrex

The Vectrex is a second-generation home console developed by Smith Engineering and manufactured by GCE, followed by Milton Bradley. It was released in 1982, retailing for $199 USD ($569 in 2021).

The Vectrex features an integrated monochrome CRT monitor, but this isn't just any CRT monitor that scans left-to-right, top-to-bottom. Instead, the electron beam is able to shoot freely across the face of the entire phosphor screen, from any angle, up to the length of the monitor. In essence, this is producing vector graphics as they are literally being generated on the machine. To this date, the Vectrex is the only vector display-based console released for the home market ever.

The Flatten-glow shader set is highly recommended to recreate this effect as it would have originally appeared.

Every game came with a color overlay sheet to be placed in front of the screen, adding static areas of color and/or on-screen decorations/HUD elements.

Being released one year before the NA videogame crash of '83 doomed its fate, being discontinued entirely by 1984 with Milton Bradley (the then current manufacturers of the Vectrex) merging with Hasbro. The Vectrex is considered a commercial failure, however despite this the system was praised for its software library, unique and novel method of rendering graphics, and built-in monitor. It was technically also the first console to feature a 3D-based peripheral.

This system scrapes metadata for the “vectrex” group and loads the vectrex set from the currently selected theme, if available.

MAME, the Multiple Arcade Machine Emulator, is a multi-purpose emulation framework which facilitates the emulation of vintage hardware and software. Originally targeting vintage arcade machines, MAME has since absorbed the sister-project MESS (Multi Emulator Super System) to support a wide variety of vintage computers, video game consoles and calculators as well. MAME doesn't use an individual “core” for each system like RetroArch does, instead the ROM itself usually contains the necessary information to accurately emulate it, thus making it specific to the version of MAME it was made for. Overall it's a very complicated subject, we have a guide specific to arcade just for it.

MAME configuration

MAME offers a Menu in-game ([HOTKEY] + South button (B SNES) or [Tab] on the keyboard). This can be used to manually adjust inputs or game settings. If you're having issues with a specific game, check the MAMEdev FAQ for that game here. For MESS systems specifically, you might find more information on MESS's wiki. All options can also be edited by opening the mame.ini file.

Translating vector-based games to a traditional pixel grid screen is never going to be 1:1 perfect, as the nature of how vectors are drawn versus pixels are incompatible. There will always be a level of “staircase” effect with any lines that aren't perfectly perpendicular with cardinal directions.

Setting the resolution multiplier to 4 and using the Flatten-glow shader is an easy way to get a close approximation of the original rendering effect.

The Vectrex features a built-in four-button controller.

Here are the default Vectrex's controls shown on a Batocera Retropad:
