One thing Arcade1up got wrong are the square gates. Ditch the square gates and make your cabinet feel authentic like the original USA cabinets! Set of 4x Circle gate replacements. Confirmed to fit Arcade 1up Cabinets from wave 2 and up. Easy to install, simply pop out the old square gates, and pop in the new Circle gates. NOTE: DOES NOT FIT ARCADE1up STREET FIGHTER, PACMAN, and GALAGA (WAVE 1). Please double check if your Pandora's Box already has circle gates before purchasing.
