Double Dragon

Double Dragon for Commodore 64 is Binary Design's 1988 home-computer adaptation of Technōs Japan's 1987 arcade beat 'em up, published in the United Kingdom by Melbourne House. It brings the series' martial-arts street-fighting premise to the C64: Billy Lee and his twin brother Jimmy set out against the Black Warriors after the gang kidnaps Marian. Designed for one player or two simultaneous players, the game turns the brothers' pursuit through gang-controlled territory into a cooperative fight through a hostile city.

The objective is to clear each area and continue deeper into the Black Warriors' domain, working from the slums through industrial and outer-city locations toward the gang's hideout. Encounters are built around groups of thugs rather than isolated duels. Billy and Jimmy must manage their remaining lives while also beating each stage's time limit; losing all life segments or letting the clock expire costs a life. This keeps forward movement central to play and makes clearing opponents only one part of surviving each section.

Combat uses a joystick and a single fire button, with direction-and-fire combinations selecting attacks. Alongside a straightforward punch, the C64 version gives the brothers forward kicks, head-butts, a backward elbow, a spinning kick, jumping moves, and a close-range hair-grab kick. Normal joystick movement covers eight directions, allowing fighters to reposition around enemies before choosing an attack. The command layout is a defining part of this conversion: it translates a varied arcade brawl into the controls available on the Commodore 64 without reducing the action to one repeated strike.

Disarmed opponents can also change the fight. The Black Warriors carry items including baseball bats, whips, knives, rocks, and oil drums, and a defeated enemy's weapon can be used against the remaining attackers. The manual identifies regular gang members and bosses such as Williams, Lopar, Linda, Abobo, Chintai, and the gun-wielding leader Willy. Their weapons and fighting styles encourage players to react to what is on screen rather than treating every enemy as the same obstacle, while the setting moves from street-level danger toward the final confrontation.

The Commodore 64 release is specifically notable as a Binary Design port, not the later and separate Ocean Software Double Dragon cartridge issued for the machine in 1991. Melbourne House's version retains simultaneous two-player play, requiring two joysticks when playing together. Its original manual openly explains a technical compromise behind the character graphics: each combatant is assembled from two smaller sprites to preserve both one- and two-player action within the C64's memory limits, which can leave a visible join around a character's waist.

As an early home-computer version of a major arcade hit, Double Dragon Commodore 64 reflects the challenge of adapting a large, scrolling arcade brawler to an 8-bit system. It preserves the fundamental appeal of the original concept: cooperative martial-arts action, improvised weapons, a rescue mission, and a route through increasingly dangerous gang territory. For players exploring the Commodore 64 library, it is a distinct period conversion with its own control scheme, technical trade-offs, and place in the wide range of Double Dragon releases.
