FYI in case you haven't seen the many warnings......
Player 3 and 4 joysticks should be mounted square and not angled. You can angle the buttons so the player stands at an angle, but keep the joystick oriented the same way as player 1 and 2.

Look at the original 4 player arcade machines and look at where the UP arrows are pointing for players 3 and 4. If there aren't any up arrows, look at the mounting bolts.
The reason for not angling this sticks is that people instinctively move the stick the direction they want the character to go even if they're standing at an angle.
People can adjust to playing on angled sticks, but it's not as intuitive. It sucks for guests who haven't used the cab before.
If you still want to angle the joysticks so be it, but don't say you weren't warned.
People on here rail on it because it's a mistake that gets made so often to the point that there are more bad examples than good ones to be found online.
It's not like other things that are a personal preference or aesthetics. It really is a mistake.
It's counterintuitive, but the truth.
And yeah, I'm not clicking on any dropbox links.

The best method is to attach pics to a post in the dedicated stickied threads in the Project Announcements subforum, then embed the links in your build thread.
This way the pics are hosted on here and aren't missing from your thread years later when you've moved onto other hobbies.
Attaching to the actual posts in the build thread would be a close second.
