I haven’t had time to mess with my arcade setup recently because of extenuating circumstances (read: a new puppy), but I’ll be picking up a complete Street Fighter 2: Championship Edition set this weekend and will hopefully have more to post regarding it soon.
For now, courtesy of Something Awful user mikeycp, I was tipped off to an interesting site. The Ambient Arcade Project is a site dedicated to recreating the experience of ’80s and ’90s arcades. They offer several single audio files that go to great lengths to emulate the ambient noise you would hear inside of arcades in this time period. It’s not directly related to candy cabs, but it’s something nice to set up and have playing in the background of your arcade room for that authentic feel.
