additional information
info 0.34b4 [Nicola Salmoria]

0.28 [Christopher Kirmse, Aaron Giles, Nicola Salmoria]

WIP:
  • 0.122u7: Changed M6802 CPU3 clock speed to 3579545 Hz in clone (Environmental).
  • 0.122u6: Changed M6802 CPU3 clock speed to 894886 Hz and replaced TMS5220 with TMS5200 in clone (Environmental).
  • 0.117u2: Aaron Giles fixed input in clone (Environmental).
  • 0.109u2: Added prom ($20 - lamp sequencer) to clone Discs of Tron (Environmental).
  • 0.106u10: Aaron Giles updated Discs of Tron to support the new artwork system.
  • 0.100u3: Removed cpu3 roms. Only clone Discs of Tron (Environmental) used the roms.
  • 0.98u4: Removed M6802 CPU3 and TMS5220 speech in Discs of Tron (Upright) and clone (Upright alternate).
  • 0.98u1: Fixed cpu3 roms addresses and removed 3rd sound channel.
  • 0.93: Added 3rd sound channel.
  • 0.63: Added clone Discs of Tron (Upright alternate).
  • 0.61: Changed visible area to 512x480 and palettesize from 32832 to 64 colors.
  • 18th August 2001: Nicola Salmoria adjusted the Discs of Tron driver for new artwork.
  • 0.54: Changed visible area to 684x642.
  • 0.53: Changed visible area to 640x600.

  • 16th November 1999: Mathis Rosenhauer fixed Discs of Tron backdrop.
  • 0.36b8: Nicola Salmoria change the mouse buttons to no longer aliases for joystick buttons, they are independently recognized. They are still considered "joystick" inputs though, so if you want to use them you have to redefine the controls in the Joystick menu. This is a minor annoyance that was needed to allow interfacing a Discs of Tron controller to the mouse port (spinner + up and down switches) while still using joystick buttons 1 and 2 for fire and deflect.
  • 0.35b12: Changed M6802 CPU3 clock speed to 895000 Hz.
  • 0.35b10: Changed M6802 CPU3 clock speed to 3580000 Hz.

  • 0.34b4: Nicola Salmoria added Discs of Tron (Upright). Renamed (dotron) to (dotrone). Mathis Rosenhauer and Brandon Kirkpatrick added preliminary backdrop support in Discs of Tron. The background image must be called ARTWORK/DOTRON.PNG. Jim Thevenot fixed hang on level 7 of Discs of Tron.
  • 0.33b4: Nicola Salmoria fixed -ror and -rol with ORIENTATION_FLIP_X games (e.g. Discs of Tron).
  • 0.30: Frank Palazzolo added a TI TMS5220 speech emulator to MAME and Aaron Giles added the TMS5220 speech to Discs of Tron.
  • 0.28: Added Discs of Tron (Bally Midway 1983). Speech is not emulated and the game stops when you reach the level where you can aim up and down.

- TRIVIA -


Released in March 1983.


Also released as "Discs of Tron [Environmental model]".


Discs of Tron was originally designed to be a part of the original "Tron" coin-op, but was cut out at the end and set aside for refinement and release as a stand-alone coin-op in its own right.


Discs of Tron is inspired by the short sequence in the movie (Tron, 1982 Disney) where the character Flynn beats another trapped program and eventually 'derezzes' him, and when Tron is introduced, beating four 'computer players' very early in the movie.


David Bagenski holds the official record for this game with 418,200 points on June 28, 1986.


A Discs of Tron 'prototype' machine was shown at the 2003 classic arcade games show 'California Extreme' in San Jose, California.
