Speed Coin (Prototype) is an unreleased arcade game from 1984. Originally developed as a coin-operated title, this early prototype version offers a look into an unfinished state of the game. It is playable directly in the browser through arcade emulation.
As a standard arcade title, insert a virtual coin (typically mapped to Shift or Select) and press Start (mapped to Enter) to begin. Use the Arrow Keys for movement and Z / X for action buttons.
