Copped this awesome Wizard of Wor cabinet for relatively cheap on Sunday - Seems like I have a ROM issue, I'm not sure where to begin; Tried putting it in test only to find out I don't have the switch on my coindoor to put her into that mode. Would greatly appreciate any suggestions or guidance.

is it just lines? I've never seen that happen so I'm not sure if it's a ram board problem or pattern board. 😮

I wish it was just lines, seems to affect the gameplay too, I can't shoot horizontally as the bullets disappear when they hit the lines.
 
Swap the RAM-boards around to check, if the behavior changes.
Thanks for the advice, changed them and now we've got yellow instead - so we've got some progress :cool:. Not sure how to proceed as to diagnosing the bad board and chip.

There is a test-ROM (or 2) for Gorf avalable.
Gorf is same Hardware.
So it should work in WOW aswell.

Thanks for the link! Took a quick look at it, will research in depth tomorrow. - I'll need a chip burner to put the test ROM on a chip eh? I've never worked w/ one before, so I'm gonna look around the forums for how to best use one.
