The Galaxian hardware was a popular arcade system board developed by Namco in the late 1970s. It powered several classic arcade games. Here is a list of games that used the Galaxian hardware:

Galaxian (1979) - The original game that the Galaxian hardware was developed for. It is a fixed shooter game where players control a spaceship and must destroy waves of attacking alien ships.

Moon Cresta (1980) - This game added a unique feature to the Galaxian hardware, allowing players to dock their spaceships to form a more powerful ship. It also introduced multiple stages and boss battles.

The End (1980) - A shooter game where players defend a planet against waves of enemy ships. It featured a distinct energy-based gameplay mechanic.

Stratovox (1980) - A vertical shooter game with speech synthesis. Players control a spaceship and must destroy enemy ships while defending their base.

Jump Bug (1981) - A platform game where players control a bug-like creature that can jump on platforms and shoot at enemies. It added a unique twist to the Galaxian hardware's capabilities.

King & Balloon (1981) - A fixed shooter game with a tower defense element. Players protect a castle from enemy balloons using cannons.

War of the Bugs (1981) - Similar to Jump Bug, this game featured platforming elements where players control a bug and must navigate levels while shooting enemies.

Omega Race (1981) - A space-themed shooter game where players control a spaceship and battle against enemy ships and asteroids.

hi-res:

Super Slam

Super Slam is clearly a bootleg of Namco's "Super World Court" on inferior hardware. The Playmark (1993) hardware lacks many features of the original such as transparency.

Un demo modificando el Montezuma original.

UPDATE1: ya salio version final https://montemaker.blogspot.com/

UPDATE2: la versión final realmente es un juego completo nuevo con perfil de puzzle-platformer. El autor ademas de mostrar buen nivel de 6502 asm, logró buenos niveles, creativos y lúdicos. (esto requiere un nuevo post con detalles de esta versión final :) ).

The Last Star Fighter: Star Trek

El easter egg ya indentificado en digital press, encontraron la parte para modificar el ejecutable para que aparezca siempre la USS ENTERPRISE, en vez de ser un tema aleatorio:

EASTER EGG: Programmers Gary Stark and Bruce Poehlman admit to putting a few hidden extras in the game, but they don’t recall how to trigger them. One that’s been seen is the Starship Enterprise will sometimes make a brief appearance (by the sun) when recharging. There is a clock timer, and if this timer is $00 or $80 at the right moment of recharging, the Enterprise will appear (picture #1). Unfortunately the timer clocks rather slow (from $00 to $FF) so it's very unlikely you will see this effect without cheating (the odds are 1 in 128), as there doesn’t appear to be a method to either resetting or resetting the timer in the code. The graphics for the Enterprise are stored in the Atari 8-bit version at $3A40-$3A42 (bytes $E7, $12, $1C).

En AtariAge esta el ejecutable modificado.
