>The Pit Fighter dump is the newest version dumped, made in 1991

After looking over the file src/mame/drivers/atarig1.cpp I thought it would be oldest release version when comparing rom set versus what is already supported.

Seeing rom labels as

136081 - 1628
136081 - 1629
136081 - 1630
136081 - 1631

I am going with a revision 1 when going by what is already in the source file and placed below rev 2 entry....


Pit Fighter (rev 9)
Pit Fighter (rev 7)
Pit Fighter (rev 6)
Pit Fighter (rev 5)
Pit Fighter (rev 4)
Pit Fighter (rev 3)
Pit Fighter (rev 2)

Pit Fighter (Japan rev 3, 2 players)



..or if the pcb did come from an actual dedicated 2 players cab, then it would be placed just below the (Japan rev 3, 2 players) entry.




Whoever adds the set later, have fun making the call to which section it goes to.

Now that Dyna Electronics Jong Shin (1986) is in working order, is it the same mahjong title that is already shown on unMAMEd site?

I didn't see the entry in the Dynax section of undumped Wiki pages.

I'm not going to argue over interpretations of the number system but it was built months later than all the sets in mame, the service mode date is 1991, all the sets in mame are 1990

But that is what makes this set weird with having newest "service mode date" as 1991 when labels read.

-
136081 - 1628
136081 - 1629
136081 - 1630
136081 - 1631
-

If it were actual revision 1, then "service mode date" should be 1990. It doesn't jive with what is already set up in source code.


If only former head-honcho Mr. G were still around to say...."Here is what we are going to do."

They're probably like the Konami numbering where each digit has a meaning rather than it being a higher = newer value.

gamenumber,rev,type,something else

so 136081-2028 is pitfighter-rev2-type0-something-something (2nd revision of the 3 player US cabinet)

in this case 36081 - 1628 it's probably the first released version of the 2 player (US? World?) cabinet

it can have a 1991 date and still be the first revision for that cabinet / region combination if they didn't distribute a 2 player version in that territory until 1991.

what surprises me is these Atari sets still showing up, I thought Aaron had access to the motherload.

but yeah basically it looks like the revisions start at 1 for any given cabinet / region combination. presumably this was sold as a conversion kit for generic 2 player cabinets after the initial 1990 wave, it isn't a bugfix for the 3 player version.

Yes, they are the same game. Dyna was the first name for Dynax. The game was listed in the Dyna section http://mamedev.emulab.it/undumped/index.php?title=Jong-Shin

but the Dyna name still seemed to be used even much later on Cherry Master stuff and the hardware seems to be entirely unrelated.

I'm not actually convinced it's all just a single company, maybe Dyna that did the Cherry Master stuff is actually different.

I think you're right. I think the mahjong company changed their name because it was the same as the slot machine one.

But just to make things more confusing, there are two other DYNAX companies in Japan now, known for bearings and aerospace products:
http://www.dynax-j.com/
http://dynax-jpn.com/

Then there's DYNAX Kougyou that does CNC machining:
http://www.jade.dti.ne.jp/~dynax/main.html

But the mahjong developer seems to have disappeared entirely. According to this the company's name was ダイナックス株式会社 (DYNAX Kabushiki Gaisha) in 1991.

Thanks. I wasn't certain since spelling is different, but good to see this old entry on btribble's unMAMEd page can be removed if a future update happens.
