Asteroids (rev 4)

0.26 [Brad Oliver, Al Kossow, Hedley Rainnie, Eric Smith, Allard van der Bas]


- Once all top ten scores are first recorded, the first game played score that does NOT reach within the 1-10 range will cause the third initial of the 10th place score to be truncated. This bug will repeatedly occur whenever a higher score proceeds to bump down the lower placed scores and eventually the first game played score that does not reach the top ten, will cause the truncation of the third initial of the 10th place score. This is a bug in the game and not the emulation. Tested on a real machine. gregf


- 0.108u5: Mathis Rosenhauer rewrote the Atari vector generators, using the schematics and actual state machine PROMs. The state machine is now emulated so timing should be much more realistic. Clipping hardware in bzone and others is emulated instead of hardcoded. Improved accuracy of clocks and various other bits of cleanup. Changed M6502 CPU clock speed to 1512000 Hz and added prom ($0 - DVG PROM).

- 0.102: Hans Andersson and Derrick Renaud updated the discrete thump sound in Asteroids to use component values instead of derived equations.

- 0.100u4: Kevin Jonas added dipswitches 'Center Mech' and 'Right Mech'.

- 0.90u3: Derrick Renaud fixed gain in Asteroids etc. broken in 0.90.

- 0.88u3: Pierpaolo Prazzoli added clone Meteorites.

- 0.85: Pierpaolo Prazzoli added conditional dipswitch support to Asterock.

- 0.76u2: Pierpaolo Prazzoli added 'Records Table' and 'Coin Mode' dipswitches to clone Asterock.

- 0.76u1: Added clone Asterock.

- 24th October 2003: Pierpaolo Prazzoli added Asterock, an Asteroids clone to the Asteroids driver.

- 0.68: Frank Palazzolo added new filter implementations to the asteroid/astdeluxe thrust sound. Derrick Renaud cleanup the discrete sound code and setup proper gain ratios and fixed saucer fire sound.

- 9th March 2003: Derrick Renaud submitted an improvement to Asteroids explosion sounds.

- 17th February 2003: Craig Aker fixed a problem in handling the LEDs in Asteroids Deluxe.

- 3rd August 2002: Ken Reneris submitted another small improvement to the Asteroids discrete sound emulation and added phosphorescent persistence emulation to the vector graphics drawing code, possibly improving the look & feel of vector games.

- 24th July 2002: Ken Reneris and Keith Wilkins both submitted improvements to the discrete sound system in Asteroids.

- 0.58: Changed palettesize from 33024 to 32768 colors.

- 18th November 2001: Frank Palazzolo reported some progress with Asteroid sound emulation - only one of the sound effects remains incorrect.

- 17th January 2001: Bernd Wiebelt fixed a bug causing static in the discrete sound functions.

- 0.37b11: Keith Wilkins made some support for discrete component sound emulation.

- 28th November 2000: Keith Wilkins sent in a discrete sound system update, fixing some sounds in Asteroids.

- 7th November 2000: Keith Wilkins sent in a preliminary version of discrete sound system emulation, not supporting any game yet.

- 0.37b3: Changed palettesize from 256 to 33024 colors.

- 0.36RC2: Added clone Asteroids (bootleg on Lunar Lander hardware).

- 28th February 2000: Juergen Buchmueller significantly improved the Asteroids sound simulation.

- 0.36RC1: Added Custom sound. Samples are no longer needed in Stratovox, Battle Zone, Red Baron and Asteroids [Juergen Buchmueller].

- 15th February 2000: Juergen Buchmueller fixed some bugs in the Asteroids sound simulation.

- 13th February 2000: Juergen Buchmueller added preliminary analog sound simulation to Asteroids.

- 6th February 2000: Jarek Parchanski added better samples to Asteroids and Asteroids Deluxe.

- 0.33b7: Renamed (asteroid) to (asteroi1) and (asteroi2) to (asteroid). Inspired by Retrocade and Vector Dream, Bernd Wiebelt changed the vector games to use translucent vectors. Color intensities had to be lowered, if it feels to dark for you now, increase the gamma correction value.

- 0.30: Brad Oliver fixed the hiscore save.

- 0.29: Andrew Scott fixed some sound problems in Asteroids.

- 0.27: Added clone Asteroids (alternate version).

- 0.26: Added Asteroids (Atari 1979). Thanks to the outstanding combined efforts of Brad Oliver, Bernd Wiebelt and Allard van der Bas, MAME entered in vectorial emulation world! All in a time, we have support for Asteroids, Asteroids Deluxe, Black Widow, Battlezone, Gravitar, Lunar Lander, Red Baron, Spaceduel and Tempest. Thanks to Al Kossow, Hedley Rainnie and Eric Smith for the code to their VECSIM emulator which had emulated these games previously on the UNIX and MAC.
