Changed visible area to 224x768 and palettesize to 32 colors. 0.124u1: Changed 'Super GX' from a clone of 'Moon Alien Part 2' to a clone of 'Galaxian (Namco set 1)'. 6th June 2009: Smitdogg - Thanks to Darran we got Kamakazi III! Renamed (galaxiaj) to (galaxiana), (galmidw) to (galaxianm), (galmidwo) to (galaxianmo) and (galtaito) to (galaxiant). It's not entirely fixed, but it's closer. hap switched Galaxian LFO sound to use the long-disabled NEW_LFO. 0.133u1: Darran added clone Kamakazi III. Changed description of clone 'Kamakazi III' to 'Kamakazi III (superg hack)'.
Also the dipswitch setting for the Taito license was the same as superg so I eliminated one. Brian Troha fixed Kamakazi III's dipswitch setting (the same as superg) and relabeled it a superg hack.
Rewrote timer code so that the pitch timer is only used when it produces audible results. Currently, we can not accurately model the switch/opamp filter circuit. Hit sound (explosion) has been hacked to increase volume. This leads to slightly different volume levels. Added possibility in discrete.h to select hardware (galaxian/moon cresta) at compile time.
Split some memory maps into sound related and not sound related parts. Moved discrete sound related pieces such as initialization into audio\galaxian.h. 0.133u2: Created discrete sound emulation for galaxian : Changed all audio related AM_WRITE to AM_DEV_WRITE.
Use DISCRETE_BITS_DECODE and save 2 nodes. Use DISCRETE_NOTE for pitch generation it is more accurate (within the one ms where the pitch changes) and saves a node. Replaced with discrete timer module DSS_TIMER now. Removed emu_timer, this was causing a stream of stream_updates only updating 3 samples. Cleaned up driver, added some section titles and comments, removed old code. Moon Cresta has a slightly different mixing stage. 0.133u3: Galaxian sound updates : Moon Cresta and Galaxian now have their respective schematics emulated, i.e. 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). 0.135: Luigi30 changed references to galaxiaj in game names to galaxiana. 12th December 2010: Smitdogg - Darran dumped an alt version of Galaxian Part X. 17th December 2010: Smitdogg - Darran dumped a bunch of early 80's bootlegs from New Zealand, mostly Galaxian and Galaga bootlegs and hacks. He scanned and vectored the Italian version of the Namco Galaxian bezel. Do - Thanks to Zorg for getting in contact with Etienne over at Dragon's Lair Fans. 0.147u4: Robbbert and MisfitMAME added clone Astrians (clone of Swarm). 0.148: Swapped gfx1 rom load for clone Galaxian (Taito) to produce correct colors so it matches the other sets. 0.148u5: Roselson (from AUMAP) added clone Galaxian (Recreativos Franco S.A. Changed description of clone (bootleg) to 'Galaxian (bootleg, set 1)'. 0.149: ANY added clone Galaxian (bootleg, set 2). Interesting Spanish bootleg where your ship grows every 2 levels thus making the game increasingly difficult, 'official' product of Recreativos Franco. Roselson added clone 'Galaxian Growing Galaxip / Galaxian Nave Creciente (Recreativos Franco S.A. DamagedGoods added clone Galaxian (Irem).
0.153: ANY added clone Galaxian (bootleg, set 3).
This is a bootleg produced in the early 90s by Datamat, Datamat still operate as Datasat. 0.154: AUMAP added clone Zero Time (Datamat). Note: ROM names are from HBMAME real names yet to be found. 0.168: Robbbert added clone Super Galaxians (Silver Systems). 0.173: Blair Quinney added clone Kamikaze (Potomac Games). Documented Galaxian (bootleg, set 2) which mixes roms from other sets (double sized program roms and kamakazi3 gfx roms). 0.175: Dyno Dastardly and Janniz added clone Galaxian (bootleg, set 4). The backround sound during gameplay is slow by about a factor of 2.
