MAMEWorld Forums - EmuChat - videos of Galactica - discrete audio and an entry for MAMETesters too

Someone (maybe from Brazil?) was asking a question and also posting videos on Mr. H's comments section.

I don't know if the roms are already supported in MAME, but I couldn't find anything. Maybe it is not dumped at this time?

The game might look like SOS while audio has a small bit of Space Invaders to it.

The game is probably 8080 hardware and could be associated with these source files.

Here is Mr. H's comments in response to Marcello (from Brazil?).

I’m trying to make sense of the Indian Battle / Space Battle Galactica post, but I’m guessing it’s been put through a translation program before being posted…

The sound hardware on most of these Taito games is discrete, so is emulated on a per game basis depending on the circuits.

I think the poster is trying to say that Galactica is missing some sounds by default, but those sound play correctly in the Indian Battle driver (although the other sounds for the game are lost)

This isn’t something I’m familiar with, but maybe somebody who has worked on adding this can look into it.
---

As one can guess, Marcello is describing how some of the analog sounds are missing (airplane motor sounds and maybe a divebomb sound too?) and wondering how Derrick Renaud did his work with Indian Battle.

The video clips should be useful for adding an entry to MAMETesters in showing how audio sounds are generated and what is missing.

If roms haven't been dumped or game isn't supported, that's one thing that would need to be done. And then if he doesn't have logic schematics (assuming some were printed for the game), he would have to make pcb layout similar to Guru's layouts. Better yet follow pcb layout for TourVision http://mamedev.org/source/src/mame/drivers/tourvis.c.html

And from there include all resistors, capacitors etc. and their respective output values and also include all adjustable pots and what sound effect each adjustable pot controls (volume, or noise pitch adjustment, or speed?)

Sorry if I did not put this post in the right place

I do not have anyone to turn to fix the emulation of a game (Space Battle Galactica-taito-Brazil) that belonged to a time of great happiness in my life.

I have the original hardware boards (it’s all right about the sounds too, minus the noise of snoring takeoff of aircraft)

watch the video:

MAME with the driver of an Indian Battle recognize sound (noise of aircraft taking off) when the galactica is played by him, and I do not know ’cause the original hardware fails (perhaps lacking a link to this and I do not know how)

This hardware also runs the game INDIAN BATTLE

The driver (MAME) INDIAN BATTLE NORMALLY works Galactica space battle

The crucial difference is that the Indian driver This battle can emulate the sound of snoring aircraft (DRIVER IN Galactica OFFICER CAN NOT MAME)

Let me explain: The Galactica’s official driver in MAME plays all sounds except the sound of takeoffs of aircraft, see and hear:

The roar of planes appears when the game is played with the DRIVER OF INDIAN BATTLE, right?

I do the following: I put the roms Galactica with the same names of the Indian driver and play the game NORMALLY (but only with the sound of the roar of AIRCRAFT) ..

The difference is that the sound produced when playing this driver and the sound it generates is only the roar of planes and not heard NOTHING MORE!

So I concluded that the sound is that of the Indian MUSIC BECAUSE batle when playing the Indian battle (note: without the SAMPLES folder), the only sound that is generated is just the background music, and the same goes for when playing galactica the SOM that is generated is just the snoring AIRCRAFT!

This above video is played with the samples folder (not the folder that appears the only sound is the background music)

This video below is the DRIVER OF THE GAME BOWLING MAME THAT BELONGS TO INDIAN BATTLE (note: the folder with samples without the directory only if the snoring HEAR OF AIRCRAFT)!

Absolute certainty: The background music produced by the Indian battle game emulated by Grandmaster DERRICK Renauld, resolves the issue:

Let me explain: The correlation FUND OF INDIAN MUSIC BATTLE = is the production of the aircraft snoring.

WHY 2 games when played by this driver (Indian battle), only plays a sound (without the samples folder), ie, when the Indian is played, is heard only the music is played for fundo.Quando galactica, is heard only the snoring of the aircraft.

So .. The key question is how Derrick has done to the music of the Indian battle (one that says, .. 1,2,3 little Indians ..) has been emulated and deploys it on the driver’s official GALACTICA

If you know how to contact him I thank

THANK YOU
