A Wico 4-way leaf switch joystick does have a restrictive diamond shaped hole. When trolling for these on Ebay keep in mind that a Wico 4-way's base is the color GREY and the Wico 8-ways are black so even if the seller claims its a Wico 4-way you should always ask the seller what color the base is. Sometimes its hard to tell from a picture. This was for quick identification for arcade operators. The 8-ways use a round unrestrictive hole. Wico also used two different joystick shaft lenths for use with metal or wood control panels. You'll probably want the long style if your cp is wood. If you or anybody needs any info or specs on 4-way or 8-way Wico leaf switch joysticks just let me know as I have both on my cab. If you're into classic 4-way games the one of these is a must. A microswitch joystick will NOT give you the authentic feel of a true dedicated Wico leafswitch joystick and I'm not just talking about the annoying clickity click that a microswitch joystick produces. The real difference in feel is due to the fact that leaf switch joysticks use a rubber positioning grommet to return the stick to center while a microswitch stick uses a spring to perform this task. The sticks have two completely different feels to them.
Thank you for the information! I'm not EXTREMELY into classic 4 way games, but I do like many of them. This is why I want it to be
1. Ball top, for me it's a must with classic games like pac-man
2. leaf switch, a whole lot more classic feel.
I'll be on the lookout on ebay for a grey base wico leaf switch joystick, you just really helped me out!
If i'm doing a gamepad hack, should I just wire up, down, left and right just to buttons on the gamepad? That would probably work, I wouldn't need another direction pad to hack, and it would be just a 4 way stick anyways...
I just hope my control panel doesn't get too crowded

, it's fairly small, and I'm doing 2 8 way joysticks with 6 buttons each, a 4 way stick(hopefully

), and probably an i-ball(I think that's what it's called) trackball(if I get my order on the ones for $2.99 a piece). I really need to lay it all out, but I don't have that visio program
