I sold an NBA Jam pcb recently. The new owner is trying to find out how to get the game from 4P to 2P, so he and and his son can play against each other, rather than on the same team.

Google is showing conflicting results in which dip switch changes this setting, or whether it's even a dip switch setting at all.

Has anyone got the board and can help with advice please? I believe it is rev1.5

It’s definitely possible as I’ve done it so that my friend and I could be on the same team.

I’m pretty sure it is a dip setting but worth him checking the game menu too.

Sorry, I don’t have mine installed to check.

Thanks for the reply

Despite spending the whole day on messenger telling him how to get the game working (turn the 5v up) and googling solutions to play 1p vs 2p (dip switch, update rom version, ask someone to make a P1 v P3 harness) the buyer has now spit his dummy out and is threatening to reverse his PayPal payment. What a waste of time

Remind me never to sell to noobs on Facebook again

some people think buying arcade stuff is like buying console stuff it aint , hes lucky the pcb works and not DOA , its a small issue probably a rom swop or dip switch  setting

i remember when i got my first cab and sf2 champin edition and then went back to the op and bought mortal kombat i remember him saying your gonna have fun setting up the extra buttons did not even have the connector for the pcb , i did not have a clue but i sorted it this is way back mid 90s i knew then arcade and  consoles two completely different animals 
if you cant contact me im out gathering winter fuel

Not sure if this might help (or confuse more...) but found this old thread on the same topic:

I looked it up. It is Dipswitch 2 switch 1.

That toggles between 2 and 4 players.

He should go into the test menu and put on free play, then press 2p start for a vs game. 4p mode will make p2 and p1 teammate.

I sent him that exact thread. He said it sounds too much like hard work and he just wants me to buy it back off him. I've suggested he sell the game himself if he wants his money back for it

Hope it resolves itself, seems unfair to you. 
If you get back and all good, I will buy for my designated cab. Which I am running tournament edition on currently but original would be good to have for it.
Was busy with work so forgot to get back to you on here about the one you had for sale.

I sold it for £165. If you want it buddy then let me know and I can try and arrange it going straight from the owner to you, and I will refund him the cash

I was following this on Facebook, I think it's been deleted now. The answer to the actual issue seemed to be either DIP swich 2/1, 2/8 or it can't be done. I guess we'll never know.
