Help with WWF Royal Rumble 4 Player Arcade Unit Please

[OldFoo]

I recently got a deal on someones garage of wifee wants it all gone..

I got a full size Commerical Air hockey

1987 Tattoo Sit Down Racer.... works perfect needs coin door



And My fixer upper...



2000 WWF Royal Rumble 4 player dual monitor.

the arcade is a split angle cabinet with a huge back door



2 coin doors 2 coin counters? one under the bucket and one up-top of the bucket..



Opened it up to a busted USB port and Error of I/O board not connected to Naomi Board..



So i cut the usb cord and soldered the wires to the top pins..

after reading 17 pages here Found one post to try the other port.

I should have known to try that I would have just cut a notch in the plastic lid and used that.



Now the game powers on, accepts credits.. and enters gameplay

Enters Self test-bookeeping etc.. no problem





but not one of the 4 joysticks is registering input or most of the buttons are not registering but a few combo moves work.



i tested each button with a ohm-meter and the are all working and not stuck



so i know its not a busted/stuck button.





Bios is D version. self test works except controller/ most button inputs.



any suggestions where to start?



one thing i did notice is the power suppy that feeds the naomi and the 2 jammas its internal fan is not moving.... dont know if its temprature activated or out.



Sound and video are fine. credit acceptors work,



So i am a bit stumped where to start





i followed the colors of the Cut usb connectors if i got the two center ones backwards could that be the issue? red white green black



if they were wrong i should still get the i/o board not connected error..



could this have anything to do with the coin counters?

Update



Fixed Usb ports game boots fine

All 3 coin mechs are working and giving credits



1-2-3-4 player start buttons work.



joystick left right up down on all 4 still do not fuction.

I can do a few combo moves



There is 2 jamma i/o boards connected via usb (replaced usb too)



started to examine the jamma wiring

Power to the jamma 1/0s is from six pin white harness from power suppy



first jamma i/0 is a sp5002A

Frst and second player are wired to this harness

there is a program button as well as a test button and one coin counter

connected under coin bin.



Monitor input/ output is thru this jamma1.



the second jamma (jamma2) Is also a SP5002A I/O



just has player 3 and 4 wires going into it



Someone seems to have modifed the wires inside so all coin trigger switches are wired to jamma 1



on the second jamma

16 coin 1

T coin 2 are stripped wires like they went somewhere a long time ago and were abandoned I can rewire them if needed





If there is no coin counter or acceptor for jamma 2 could this cause the malfuntion ?





Any help where to start is appricated
