World Rally PCB issue Part 2!


Recommended Posts

Hi guys

I have a world rally board with issues

Its described in this thread that I came across here -

https://www.aussiearcade.com/showthread.php/27349-World-rally-security-processor-reload

As described the game starts up ok then after the first crash its all over the place , a bit like open world driving!

I have contacted the members in that thread but not sure if they are still active waiting to hear but thought I would put it out there

to see if anyone else would know how to fix it

Option 2 is find a working board - again any leads would be appreciated

Cheers

Ok Part 2 problem ??

 

I picked up 'working' board on Feebay that arrived today

So put it in the cab and unfortunately the picture is all over the place (see pic)

Thinking it was the monitor I adjusted it and still nothing so

I checked voltages -all good

Put in the old board that has the problem -picture is good

Put in a 60 in 1 - picture is good

Put the new world rally board in another jamma cab and picture is good and plays fine

but not in the original cab

Also changed power supply (from the other cab that it worked in) and also a different jamma harness but nothing changed

One thing I did notice is that when the screen picture changes eg - from intro to start or picking the track to starting etc the picture comes good for a split second

then goes wavy

So in summary the board works in a different cab

The monitor in the original cab works with the old board and a 60 in 1 ???

 

What am I missing

Bingo !

So I bypassed the video ground from the board (pin 14) and put it on the power supply ground and it worked

On the new board I got pin 14 (Gnd) doesn't do anything then?? But on the faulty board that came with the cab it works

I got the new board from Greece so Im assuming it might be a different setup over there than the original board that I have although they look identical

Or some other reason Im missing

Either way its working and its a fun game

Next is to give the cab a makeover

Hi There,

Quick question. Is the accelerator for World Rally a microswitch as in on/off or a pedometer style. I recently bought a World Rally sit down version but the accelerator looks a bit dodgy and I just want to double check. Thanks.

My cab gas a pot (dirty and rusty!)

The cab was a LAI APB at one stage so not sure if the accelerator is standard or not but it works fine
