Okay, so I will happily stand up and say that while I've worked around arcade games and owned my own for a long time, I have no idea the answer on this, so sorry if this is obvious or something...

I have a four player Midway cabinet. Plug in NBA Jam, and it works great. I'd like the ability to plug in my TMNT board and play with four players also.

How can I go about converting the player 3/4 plugs so that they will work with both boardsets? From what little I know, I feel like someone should have already made a little nifty converter for this, but I don't think they have. Otherwise, I'm thinking that I am looking at getting a Konami 3/4 player harness adapter (are they available somewhere? I thought I saw them once, but can't find them now) and wiring that in beside the Midway ones, and then labeling them near the boards so when I swap I can just swap those. Would that work?

I have to believe that someone has already done this, as I can't be the only guy with the desire to run both NBA Jam and TMNT in the same cabinet sometimes!
 
you just need to find 10 pin connectors that will go to the 3p and 4p layers on the Konami board. The pin code is in most of the Konami manuals. From there just wire them to the same style molex that comes off of your cab to the Midway board.

I need to get around to build a board that plugs into my Sega 4P cab where I have harnesses to plug in my NBA Hangtime and my Konami boards...

That's what I was figuring, but has anyone made this part already? It seems like this should be something common, and if someone else does it for a cheap price, I'd rather buy something instead of spend a bunch of time doing it by hand myself. If not, I can definitely do the hand method, I'm just trying to be lazy ;)
 
no it's just wiring so anyone can do it... there are too many variables. What cab... what boards.

Okay, dumb question perhaps -- like I said, I don't usually try to do stuff like this...

Wouldn't all of the Konami boards use the same harnesses? And, wouldn't all the Midway ones use the same harnesses? Like, I know that NBA Jam has the sound control elsewhere, but wasn't that the point of the JAMMA games to begin with? Easy switching?

Again, while I've got my hands rather dirty in a lot of different projects over the past 15 or so years, I have never poked around with changing boards like this until now that I have a nice four player cab to actually do some stuff with. I really don't know what I'm talking about here, and after a bunch of time looking for info, I figured I would just ask :)
 
The 3rd and 4th player is where the problem is going to be .

The first and the 2nd player should play fine off the Harness.

I have a NBA Jam machine I've tryed other boardsets in the machine .. Other then having too mess with the monitor games loaded fine.

My other 4 player game the Main Event plays most 4 player games without any problems .

Capt America and others where plug and play ..

Yup -- got that. I've had a 2 player JAMMA Cabinet forever (a Namco one with Tekken 3 in it, which I bought completely not for Tekken 3 but for how nicely it front loads boards). I have a lot of experience with messing with that JAMMA harness and different things and how easy those were, and I guess I was under the mistaken impression that 4 players were more or less the same thing.

Obviously, they aren't, so I'm trying to figure out what I'm doing before I jump in head first ;)

Do Data East titles (like Capt America) use the same harness as Konami ones?

Yes Captain America uses the same 10-pin connectors as a Konami cab. I also have a Growl Board by tatio that uses it. I think NBA Jam uses the same wiring for the extra players as Blitz and Gauntlet Legends/Dark Legacy but I'm abit new at this too.

I've swapped a ton of stuff in and out of my 4P Xmen conversion since I got it about 90% working and I'm sure there's a thread on what works in konami cabs around here somewhere.

I actually know this a bit -- NBA Jam would swap with some Blitz games, but the Gauntlet games and later Blitz games require 49 way joysticks, so they wouldn't be straight up swaps.

I believe that the straight up swaps would be:

NBA Jam
NBA Jam TE
2-on-2 Open Ice Hockey
Blitz '99
NBA Hangtime
NBA Maximum Hangtime
Rampage World Tour (3 player only)

If anyone wants to correct me, that would be great :)
 
The 49 way joystick games can be set to work with 8 way joysticks. I know Blitz can be set for low res, but I can't remember if the Gauntlet game can be or not.
 
Blitz, Gauntlet Dark legacy and Legends can be set for 8 way joysticks and std res monitors.

I officially both love and hate you guys right now. I don't need to spend that much money, but...

Same thing with NBA Showtime?

My possibilities just greatly expanded. LOVE those Gauntlet games...
 
Yeah I wasn't sure on the Gauntlet, I know you can even get VGA out on it if you wanted to.

Fair warning...8 way and standard res are going to really change your experience on these games.
 
True, but it will give me an excuse to get the boards. Then, getting the 49 way joysticks and building a swappable control panel will be the next thing I'll want to do...

I can live with standard resolution...
