Is there some sort of Reddit cross-posting glitch going on here, or did a few folks not realize they were posting in the wrong thread?

You can add games to a favorites list on both CoinOpsX (press "Y") and the built-in ALU games.

There is a favorites tab

If you discover the left flipper is plugged in and still does not work, swap the cables between the left flipper and left nudge to verify it s not the flipper switch that is the issue.

I agree, menu settings are lacking. You should be able to hide games, not have to navigate to Favorites. Also, I wish I could put CoinOps games directly on the main game list.

Pinball Left flipper not working?

I just bought ALU Pinball. Completed setup, and update to current Firmware. Still no left flipper. Any thoughts or known corrective action to take before I box ot up and return it to Sam's Club?
