This is the Family Computer (Famicom) port of Contra.

Probotector II Is the European port of Super C (NES). Like in the original game, the main characters and enemies were changed to robots.

Contra (also known as Gryzor in Oceania and Europe), is a 1987 run and gun action game developed and published by Konami originally released as a coin-operated arcade game on February 20, 1987. The game had multiple ports, including for various computer formats. Several Contra sequels were produced following the original game.

The action franchise that started it all is celebrating its 20th anniversary with an all-new adventure on Nintendo DS! Set after the events of Contra III: Alien Wars, the game follows mercenaries Bill Rizer and Lance Bean as they battle to save the world from a new extraterrestrial threat. Contra 4 takes advantage of the dual screens of the Nintendo DS to deliver larger than life action, with massive enemies, detailed platforming and mind-blowing set pieces.

Contra is the NES port of the homonymous 1987 arcade game. It is a run and gun action game developed and published by Konami. The NES port was originally released in North America, and it lacks the cutscenes and other details present in the Japanese version which was released a week later.

Operation C is an Action game, developed and published by Konami, which was released in 1991.

The game centers around the main character of Apollo who progresses through the game in an alternating format that switches between platform, side-scrolling action and side-scrolling shooter action. The goal of the series is, stereotypically, to destroy an evil boss Goruza, rescue a princess (in this case, Princess Maria) and save the planet.

Vulcan Venture (also known as Gradius II: Gofer no Yabo) is a side-scrolling shoot ’em up developed by Konami and released in arcades in 1988. Players control the Vic Viper spacecraft as it battles the Bacterion Empire, now led by Gofer. The game builds on the original Gradius by retaining the power-up bar system while introducing selectable weapon configurations and expanded abilities such as different missiles, double, and laser options. It also incorporates elements from Salamander (Life Force) and introduces a stage focused entirely on consecutive boss encounters.
