MAME Info:

0.103u4 [David Haywood]


- 0.145u6: Converted Galaxia driver to use MAME tilemap. Improved colors and hooked up CVS stars circuit [hap].

- 0.145u5: Some work on Galaxia collision detection, seems very similar to CVS. Added Galaxia bg scroll (see level 1 enemy swarm). Added preliminary bullet and notes. Some driver cleanup. Improved enemy bullet collision detection. Promoted game to working state. Corrected romnames [hap]. Changed visible area to 240x240. Added dipswitches 'UNK04' - 'UNK17'.

- 0.139u2: Mariusz Wojcieszek added sound support to Signetics S2636 (by using VC4000 sound support from MESS). Hooked up sound to Galaxia.

- 0.135u4: Fabio Priuli fixed all sets in drivers using S2636 video chip.

- 0.135u3: Fabio Priuli converted Signetics 2636 video chip to be a MAME device and updated drivers using it accordingly.

- 0.130u1: Robbbert added inputs for Galaxia. Galaxia is semi-playable. NOTE: After inserting a coin, it can take a few seconds to respond. Added dipswitches 'Freeze', 'Coinage' and 'Lives'.

- 14th August 2008: Tomasz Slanina - Emulation status update: (Some) inputs are mapped, bg scroll finally implemented. But game is NOT playable. The main problem is the missing collisions between sprites and BG (player's ship is not a sprite, but bg object) as well as between sprites generated by different video chips (there are 3 of them). If someone has access to Signetics 2636N (not 2637) datasheet/manual - please mail me ([email protected]). Any help will be appreciated. Btw. - Galaxia Flyer. Looks like it's other version of game - no time bar, different gfx and layout...

- 0.126u5: Tomasz Slanina fixed ROM mapping and added preliminary video emulation to Galaxia.

- 12th August 2008: Tomasz Slanina - Galaxia (Zaccaria 1979) emulation. Few pics from attract mode.

- 0.103u4: David Haywood added Galaxia (Zaccaria 1979).

- 1st July 1997: Paul Swan dumped Galaxia. Taken from an untested board. The game uses a Signetics 2650A CPU with three 40-pin 2636 chips.
