View Full Version : Pac Man is Cyan

3rd August 2006, 01:22 PM
Hi there

finally got the gohst muncher / uniwars cocktail going and all is well, ok is is 95% there

The two games seem to be showing yellow as Cyan - quite odd. This means the little uniwars aliens are cyan and more importantly so is pac man (ghost muncher)

I initally thought red is not working - however the cherries are showing on ghost muncher as red as are the dots on the maze. Red is working

the red pot i don't think is working as it was the only one that didn't give the red haze when turned up all the way. any way to test this?

I am going to check the wiring etc to see if it is bad connection between the harness and monitor (harness is old and the pins look a bit cruddy)

It isn't the board as the yellows show up when hooked up to my test rig

any suggestions? If photos would help i can post these

Yellow = Green + Red
Cyan = Green + Blue

Maybe a short betwen Red and Blue?
Maybe a harness cock up, swapping red and blue?
Maybe green is to low?

Cheers Mike

this relfects some of my thinking - will look at the short issue

but I am going to go harness first

Actually, rethinking...yellow = red + green + a little blue to make it lighter. Maybe a dodgy solder on the red.

red at harness or at monitor?

but start simple
