Artwork available


- The backround sound during gameplay is slow by about a factor of 2. dropdeadhippie (ID 00443)


- 0.150: Added 'Galaxian Custom' sound.

- 0.149: ANY added clone Galaxian (bootleg, set 2). Changed description of clone (bootleg) to 'Galaxian (bootleg, set 1)'.

- 0.148u5: Roselson (from AUMAP) added clone Galaxian (Recreativos Franco S.A. Spanish bootleg).

- 0.148: Swapped gfx1 rom load for clone Galaxian (Taito) to produce correct colors so it matches the other sets [Brian Troha].

- 0.147u4: Robbbert and MisfitMAME added clone Astrians (clone of Swarm).

- 16th April 2011: Mr. Do - Thanks to Zorg for getting in contact with Etienne over at Dragon's Lair Fans. He scanned and vectored the Italian version of the Namco Galaxian bezel.

- 17th December 2010: Smitdogg - Darran dumped a bunch of early 80's bootlegs from New Zealand, mostly Galaxian and Galaga bootlegs and hacks.

- 12th December 2010: Smitdogg - Darran dumped an alt version of Galaxian Part X.

- 0.135: Luigi30 changed references to galaxiaj in game names to galaxiana. Changed description of clones 'Super Galaxians (galaxiaj hack)' to 'Super Galaxians (galaxiana hack)' and 'Space Invaders Galactica (galaxiaj hack)' to 'Space Invaders Galactica (galaxiana hack)'. Fixed unable to use normal coin slots (coin lockout) in clone Kamakazi III (superg hack).

- 0.133u3: Galaxian sound updates [Couriersud]: Moon Cresta and Galaxian now have their respective schematics emulated, i.e. Moon Cresta has a slightly different mixing stage. Cleaned up driver, added some section titles and comments, removed old code. Removed emu_timer, this was causing a stream of stream_updates only updating 3 samples. Replaced with discrete timer module DSS_TIMER now. Use DISCRETE_NOTE for pitch generation; it is more accurate (within the one ms where the pitch changes) and saves a node. Use DISCRETE_BITS_DECODE and save 2 nodes.

- 0.133u2: Created discrete sound emulation for galaxian [Couriersud]: Changed all audio related AM_WRITE to AM_DEV_WRITE. Moved discrete sound related pieces such as initialization into audio\galaxian.h. Split some memory maps into sound related and not sound related parts. Added possibility in discrete.h to select hardware (galaxian/moon cresta) at compile time. This leads to slightly different volume levels. Hit sound (explosion) has been hacked to increase volume. Currently, we can not accurately model the switch/opamp filter circuit. Rewrote timer code so that the pitch timer is only used when it produces audible results. Brian Troha fixed Kamakazi III's dipswitch setting (the same as superg) and relabeled it a superg hack. Also the dipswitch setting for the Taito license was the same as superg so I eliminated one. Changed description of clone 'Kamakazi III' to 'Kamakazi III (superg hack)'.

- 0.133u1: Darran added clone Kamakazi III. hap switched Galaxian LFO sound to use the long-disabled NEW_LFO. It's not entirely fixed, but it's closer. Renamed (galaxiaj) to (galaxiana), (galmidw) to (galaxianm), (galmidwo) to (galaxianmo) and (galtaito) to (galaxiant).

- 6th June 2009: Smitdogg - Thanks to Darran we got Kamakazi III!

- 0.124u1: Changed Moon Alien Part 2 (moonal2), Moon Alien Part 2 (older version) (moonal2b) and Super GX (supergx) to Galaxian clones. Changed visible area to 224x768 and palettesize to 32 colors. Changed description of clones 'Galaxian (Midway)' to 'Galaxian (Midway set 1)', 'Galaxian (Midway, old rev)' to 'Galaxian (Midway set 2)', 'Super Galaxians' to 'Super Galaxians (galaxiaj hack)', 'Galaxian Part X' to 'Galaxian Part X (moonaln hack)', 'Space Invaders Galactica' to 'Space Invaders Galactica (galaxiaj hack)', 'Galaxian Part 4' to 'Galaxian Part 4 (hack)', 'Galaxian Turbo' to 'Galaxian Turbo (superg hack)', 'Swarm (hack of Galaxian)' to 'Swarm (bootleg?)' and 'Star Fighter (bootleg of Galaxian)' to 'Star Fighter'.

- 0.37b12: New filtering code for the audio mixer. It is applied to audio streams generated at a sampling rate different from the sound card's one, improving quality. Some examples with a very audible difference are Galaxian.

- 26th February 1999: Zsolt Vasvari has added several clones (for Smash TV, Galaxian, Rampage, Satan's Hollow, Bosconian).

- 0.35b2: Nicola Salmoria fixed (?) the title in clone Galaxian Part X.

- 10th January 1999: Malcor dumped Galaxian (Taito).

- 0.31: Known issues: Bullet placement is not correct in cocktail mode. Changed description of clone 'Galaxian Part 1' to 'Space Invaders Galactica' and clone 'Super Galaxian' to 'Super Galaxians'.

- 13th April 1998: Malcor dumped Moon Alien Part 2 (older version).

- 0.29: Andrew Scott improved the Galaxian background hum, it also is no longer incorrectly played in Moon Cresta & others. In some games (e.g. Pacman, Galaxian, Rally X) the NumLock and CapsLock leds emulate the 1 Player/2 Players start lamps [Sean Gugler].

- 0.27: Andrew Scott and Robert R. Anschuetz II improved sound support in Galaxian and clones. The background noise is now emulated, while the shoot noise still requires a sample. These changes also affect other games using the same sound routines.

- 0.26a: Mirko Buffoni worked with the wrong source, now everything is back to normality in Galaxian.

- 0.25: Robert Anschuetz provided infos about how to enable a shot sample with Moon Quasar, Moon Cresta, Galaxian and clones.

- 0.18: Nicola Salmoria added some lousy noise to Galaxian.

- 0.14: Nicola Salmoria added high score saving to Galaxian.

- 0.06: Star background in Galaxians & co [Nicola Salmoria]. The way I calculate it is probably not correct, anyway it looks reasonable.

Game is playable with accurate colors and limited sound. Control: Arrows = Move around, CTRL = Fire and F2 = Test mode. There are so many clones here that I'm not even sure which is the "original" one. The dipswitch menu might display wrong settings. Compiled from information provided by friends and Uncles on RGVAC. Info on Galaxians taken from Arcade Emulator by Robert Anschuetz. Known issues: Only one sound channel is emulated, and I'm not sure it's correct. No star background. What does dipswitch 6 do?

- 4th January 1997: Malcor dumped Galaxian Part 4 (hack).
