I have a Fist Tales and the dmd shows dots "flashing in the wrong places" during some animations.
It happens during attract mode and only for a few items.
attached pictures for Grand Champion and Top Anglers - they always show the glitch

- The latest game ROM in newly installed
- this happened on the original orange dmd an the new Color DMD LED

Is this corrupted game code?

new ribbon cables from pinball life.

Could this just be rom corruption? Just ordered and installed the latest rom chip

good idea. thanks. You looked at my profile to know I had a JM. wow

The fishtales has a rottendog DMD controller board, so I thought maybe that was not the weak link.
I'll find out soon enough

well, well, well
The dmd controller borrowed from JM fixed the issue.
AND the text is BLUE instead of WHITE.

Dmod So then I need to get another rotten dog replacement dmd controller for Fish Tales?
Thanks again

I agree Homepin - that's the best approach

I fairly new to the hobby and just tend to order new parts rather than refurb or search out originals.
Just wanna get back to playing - right? heh
