Building a cab with ONE game

<< < (3/14) > >>

thomas_surles:
You should do something totally different like an earthworm jim cab or a zelda cab.

Malenko:
ONE game? only if it s a great one (like Galaga or Arkanoid), otherwise I'd at minimum make it a JAMMA cab, so you can swap boards easy peasy.

JAMMA stands for Japanese Arcade Machine Manufacturers Association, a set of standards developed for board pinouts. This was designed to make board changes easy, just take out the old game and plug in the new.

The JAMMA wiring standard was introduced in 1985. Arcade cabinets wired to the JAMMA standard can be made to play all games built to this standard, simply by installing the circuit boards for the new game. By the 1990s, most new arcade games were JAMMA standard. As the majority of arcade games were designed in Japan at this time, JAMMA became the de facto world standard.
