Thanks TAB & Destruk for all the work you have put into building tables for us!


Best Regards,

Enjoy the extra resolution the FS gives this -- great art work TAB!! I really enjoy this table despite the issues -- then again EBD is one of my favorites I had no problems with tilting this go around, however on my 4th ball it did add a 2nd player. It just gives the table extra personality in my mind I did notice some other differences -- sometimes the flipper flutters (thought it was my shift keys going from overuse). Also when you nudge, you see the table move on the screen -- I thought that doesn't happen in VP9. Thanks again TAB and Destruk!

Thank you chaps - looking forward to loading it up the weekend.

Removed some helping walls, some walls draw shadows-was wrong.
Both upper plastics taken from EBD, the cowboy one are too bad.

Thanx guys!

I am just curious on the relationship between this table and 8 ball deluxe. Who made this table and why is it different. I am always interested in the different games and their history. Thanx.

Also, anyone have some sort of BG for this? thanx.

TAB posted a backglass here.

IPDB says - LTD, of Campinas, São Paulo, Brazil (1977-1984)
A copy of Bally's 1981 'Eight Ball Deluxe'. All parts were made by LTD in Campinas, São Paulo, Brazil.
Eight Ball Deluxe was made first and then LTD copied it - they did that with a lot of different games.

Differences - no speech
Different music
Different hardware and operation

LTD (Brasil)
------------
by Gaston

Emulating LTD was a wee little difficult as information is relatively sparse.

There are some very good schematics for system III redrawn by Newton Pessoa (thanks!)
but somehow they wouldn't align to what is happening on the CPU side.
Still, I somehow came up with a DMA solution for all of the inputs and outputs.
Maybe one day I'll find out how they really did it, and rework the driver,
but for the moment it's working OK...

System 4 was hell at first, but some terribly good fun in the end.
LTD switched over from a simple 6802 CPU to the 6803 MCU, and had me sitting and wondering
where all the inputs and outputs were connected, as seemingly NOTHING was going on!
Of course I had to hook up the internal register read/write handlers, and voila,
CPU ports were suddenly available (imagine me slapping my forehead at that point)!

I had a manual for system 4 written in Portuguese that was a bit of a help,
but I still had to guess most of the data; it seems to work fairly good now,
only whenever a sound is played, this seems to interfere with the displays, which is
odd because they run on completely different outputs!?

Fun fact: LTD obviously didn't use any IRQ or NMI timing on system 4 at all!
They also drive the flipper coils directly by two pulsed solenoid outputs.

Hardware:
---------
CPU: M6802 for system III, M6803 for system 4 with NTSC quartz
DISPLAY: 7-segment LED panels, direct segment access on system 4
SOUND: - discrete (4 tones, like Zaccaria's 1311) on system III, maybe something better on Zephy
- 2 x AY8910 (separated for left & right speaker) for system 4 games


Gameplay Differences - 5 ball game - you might be able to set it to 3 or 4 balls, just I don't know how.
The ball configuration in the middle of the playfield is different.
Different artwork
Cowboy/Deluxe Targets score 2000 instead of 3000
Bonus scores 3000 per ball instead of 2000 per ball
Bumpers are not lit
DELUXE backglass lamps are removed
Solenoid Aux Expander board is gone - meaning each solenoid has it's own discrete designation instead of being doubled up with the aux board.

What else do you notice?

videogenesis - thanks for the comment about the sound missing the alternate option - it's either a dipswitch, a different romset revision, or "A" in the diagnostic text that we can't change yet.

[maceman]

Thanx! That BG works just fine!

Interesting write-up. We can really see the amount of thought and work that goes into each release...people just don't realize.
I don't see anything different than what you covered above. It actual plays very well. I get frustrated with EBD sometimes as it is tough, but this one plays better for me

To get different music and 3 players instead of 4 players, we need different roms -
COWBOY EIGHT BALL LTD (Brazil) Clone of Eight Ball Deluxe (Bally). CPU System 3 (3 players). Manufactured in 1981 by LTD Brazil
COWBOY EIGHT BALL 2 LTD (Brazil) Clone of Eight Ball Deluxe (Bally). CPU System 4 (4 players). Manufactured in 1983 by LTD Brazil

Quero mencionar um detalhe importante sobre as LTD . Originalmente entra em jogo se apertar start e houver créditos , isto é , se houver créditos você pode entrar em jogo na bola 2 , 3 , 4 ou 5 . Isto parece ser defeito mas foi fabricado assim !
(google translate):
I want to mention one important detail about the LTD. Originally comes into play and start to squeeze any credits, ie credits if you can come into play on the ball 2, 3, 4 or 5. This seems to be defective but it was well made​​!

Dboyrecords hasn't created a b2s for this one yet? Quick and dirty should be fine
