Lexibook Console Colour - Minnie Mouse [Team Europe]
Lexibook Console Colour - Disney's Planes [Team Europe]
- improved descriptions of several mpu4vid sets based on boot information [David Haywood]
* New machines marked as NOT_WORKING
----------------------------------
Diana Olakoa [Victor Fernandez (City Game), ClawGrip]
* Renamed 'Microdar DPD' as 'Diana Bifuca' ('Microdar DPD' is the hardware name, not the game name)
* Rename 'microdar' as 'dibifuca'
* Add Microdard-V5 PCB ASCII layout
mw8080bw: improvements to 280zzzap netlist audio
* Noise-based sound effects corrected. The original strength of the
zener noise voltage was about three orders of magnitude too low
for the current being passed through a zener of this type. This
prevented the noise generator from working as designed and made
the noise far too weak for the noise-based sound effects to work
properly. Those effects now sound much closer to the real hardware.
* Implemented faster high-level emulation version of noise generator.
(Credit to couriersud for suggesting this.) The corrected noise
voltage made the component-level emulation of the noise generator
much too demanding on the minimum timestep needed to produce
accurate results without unrealistic voltage spikes, and so will
not run accurately at reasonable emulation speeds. But by replacing
it with a simple but effective AFUNC()-based comparator, we get a
functionally similar noise signal generator that produces
effectively identical output while still being able to run with
48 kHz static timestepping. So we get both decent emulation speed
and correct-sounding noise effects.
* Added output voltage clipping on post-crash sound to remove
voltage spikes, resulting in a smoother, more accurate sound.
(Credit to Aaron Giles for suggesting this clipping method.)
* Changed output to be taken from second LM3900 output opamp
(inverted signal) for smoother waveform and better tone quality.
* Added master volume potentiometer which can be user-set, set to
midpoint by default. Adjusted output scaling and offset to match.
* Various explanatory comments expanded or corrected.
* Added netlist simulations for the following games: Space War, Barrier, Star Hawk, Speed Freak, Star Castle, War of the Worlds, Sundance, Tail Gunner, Rip Off, Armor Attack, Warrior, Solar Quest, Boxing Bugs. Removed previous samples-based sound. [Aaron Giles, Couriersud]
* Added built-in minimal artwork for Warrior. [Aaron Giles]
* Changed speaker maximum sample tracking to be based on new compile-time define SPEAKER_TRACK_MAX_SAMPLE instead of MAME_DEBUG. [Aaron Giles]
* Modernized 74164 and 74393 netlist TTL devices. [Aaron Giles]
