additional information

info

0.08 [Nicola Salmoria, Michael Strutts]

NOTE:

Clone Space War (Sanritsu): 1. Game misbehaves frequently, usually on 2nd level. 2. I seem to recall that the flashing ufo had its own sample sound, a sort of rattling noise. Unable to find evidence of this in the hardware.

Bugs:

Gray line of pixels on lowest invader head in demo, need overlay adjusted slightly. john_iv (ID 02149)
Clone superinv: When set is booted, there is automatically a credit available. Tafoid (ID 02061)

WIP:

0.128u2: More Discrete module optimizations [Derrick Renaud]. This module optimizations speed up Space Invaders 9%.
0.126u4: Robiza fixed built in red color overlay goes too low and shows on top line of invaders heads in Vista only.
0.123u1: RansAckeR added DIP locations for clones Space Invaders (TV Version), Space Invaders (CV Version) and Invasion. Also fixed coin2 for clones Super Invaders and Invasion.
0.117u1: Changed description to 'Space Invaders / Space Invaders M'.
0.114u2: Derrick Renaud added full discrete emulation of Space Invaders. I think people are going to be too used to the current samples and their relative levels. The new relative levels are determined by the mixing resistors. There are all different versions of the sound board, that all have slightly different sounds/components. This should be the proper Midway sounds. Removed Samples sound (1. - 9.wav) and added Discrete sound in Space Invaders and some clones.
0.113u2: Shuttle Invader display is shifted off screen now, but the PCB notes confirm that it's a different hardware, so it will need its own driver anyhow [Zsolt Vasvari]. Changed 8080 CPU clock speed to 1996800 Hz, visible area to 224x260 and VSync to 59.541985 Hz in clones sicv, sisv, sisv2, spacewr3, spcewars and darthvdr.
0.111u4: Zsolt Vasvari and Derrick Renaud added non-memory mapped coin counters to Space Invaders. Changed 8080 CPU clock speed to 1996800 Hz. Added dipswitches 'Unknown' and 3x 'Unused'.
0.111u2: Derrick Renaud added proper watchdog to Space Invaders.
0.111u1: Tomasz Slanina added clone Darth Vader (bootleg). Added new samples (11-18.wav) to the Invaders set. Robert added the game toggle switch to Jatre Specter (move right for game B; otherwise it's game A).
0.109u1: Robert fixed 'Bonus Life' dipswitch in clone Space War Part 3, Super Invaders (EMAG), Super Invaders (bootleg) and Space Invaders (Model Racing). Changed dipswitch 'High Score Preset Mode' to 'Bonus Life' in Space King. Added Speaker sound to clone Space War Part 3.
0.108u4: Robert fixed sound and improved dipswitches in clone Space War (Sanritsu). Added Speaker sound (soundspeaker.c) and 'Bonus Life' dipswitch.
0.105u4: Giuseppe Gorgoglione fixed UI positioning when artwork is enabled (OK screen doesn't fit on the screen, nor does the FPS counter).
0.96u2: Dave Widel added clone Cosmic Monsters 2.
0.95u4: David Haywood added clone Space Invaders (Model Racing).
25th March 2005: Dave Widel - The main difference in Cosmic Monsters II is the mothership drops a row of replacements periodically. Thanks to Art Mallet (http://artsarcadegames.com/index.htm) for loaning the board from one of his machines. Art is the source for Fluke 9010 parts and accessories as well as one of the major sellers of video game parts.
0.88u2: Derrick Renaud added to DISCRETE_555_ASTABLE an option to disable oscillation if R1 (charge) is out of circuit (will be needed by Invaders).
0.87u3: MASH added clone Space Invaders Part Four (bootleg 1978).
0.85u2: Added 'Service Mode' dipswitch to Space Invaders (TV Version).
0.80u1: Pierpaolo Prazzoli added clone Invasion. David Haywood added clone Super Earth Invasion (set 2). Renamed (earthinv) to (searthin).
0.75: Nathan Woods fixed a screenshot handling bug that affected Space Invaders.
0.74u2: Added 'Space Invaders Test ROM' (19??) for region cpu1 ($0).
30th September 2003: Mike O'Malley submitted an addition of Space Invaders and Galaxian test ROMs.
0.53: MASH added clones Space Attack (Video Games GMBH 1978) and Jatre Specter (set 2). Renamed (spaceatt) to (spaceat2).
0.37b3: Major redesign of the artwork support. All the drivers need to do is call overlay_create() or overlay_load() and the rest is handled by the core. Opacity/translucency support in 16-bit mode. Check out Space Invaders for example, the colored strips that make up the overlay is faintly visible under the black areas [Mathis Rosenhauer, Zsolt Vasvari].
0.37b2: Added clones Super Invaders (Zenitone-Microsec) and Super Invaders (bootleg).
2nd May 2001: Lee Taylor added another Space Invaders clone.
0.37b1: Zsolt Vasvari emulated the red saucer/ufo sound in Space Invaders (SN76477 sound), this sample is no longer needed (the other samples are still required). Added SN76477 sound and removed samples (0., 10-18.wav).
22nd March 2000: Zsolt Vasvari added SN76477 support to Space Invaders.
0.36RC2: Renamed (si_tv) to (sitv) and (logitec) to (invaderl).
0.36b16: Pongkang added clones Space King (Leijac 1978), Space War (Sanritsu) and Space War (Leijac).
26th January 2000: Pongkang added clone Space King and two different Space War clone games to the 8080bw driver.
0.36b15: Added clone Jatre Specter (Jatre 1979).
15th January 2000: Frank Palazzolo added clone Jatre Specter to the 8080bw driver.
0.36b11: Added clones Space Invaders (Logitec), Space Invaders (SV Version 2) and Space War Part 3 (bootleg).
0.35b4: Changed description of clone 'Alien Invaders 2' to 'Alien Invasion Part II'.
0.35b2: Lee Taylor added clones Alien Invaders 2, Space Invaders (CV Version), (SV Version) and (TV Version).
0.34b8: David Winter added clone Super Invaders.
0.33b7: Martin Sandiford added Cocktail mode support.
0.30: Lee Taylor added clone Cosmic Monsters (Universal 1979). Aaron Giles support dirty rectangles in Space Invaders & clones. Samples can also be loaded from a common directory for variations of the same hardware. For example, all Space Invaders clones will load samples from the invaders directory.
0.21: Minor adjustment to Space Invaders color strips.
0.20: Dave W. provided a new set of invaders samples. Should be better, though.
0.18: Hiscore save in Space Invaders (Invaders only - not clones).
0.16: Tormod Tjaberg provided updated Space Invaders (+clones) drivers which support sound. They use samples, derived from Michael Strutts' emulator.
0.09: Space Invaders now seems to work correctly. Deluxe version still doesn't work properly.
0.08: Some support for Space Invaders (+ some clones) but it doesn't work well. Added Space Invaders (Midway 1978), Super Earth Invasion, Space Attack II, Space Invaders Deluxe and Galaxy Wars. Space Invaders information gathered from the Space Invaders Emulator by Michael Strutt. Issues: The color stripes are not placed correctly. Bullets and aliens sometimes stop for an instant Interrupts are not handled well. You should run the game with "-frameskip 1", otherwise it will try to refresh at 120 fps.
