Hi team,

I have a dedicated House of the Dead 1 arcade. Everything is working perfectly and I was able to score a Virtua Cop 2 board set off eBay. So I basically zip ties the boards so they hang outside of the metal case House of the Dead is in inside the machine. It makes it easier to switch the cables from each game whenever I want to switch between the two games.

The only issue I am having is Virtua Cop 2 has these noticeable wavy lines when the game is on. Everything still works great but I am wondering why they only appear on this game and not House of the Dead. Could it be a grounding issue? Thank you!

Here’s a quick video to give you an idea.

grounding??
Sorry, somewhat new to arcade repairs. Do I need the green ground wire to be attached to the pcb boards? I heard somewhere that model 2 games need to be grounded… not really sure what that means. Sorry I’m a noob
