I bought some new replacement buttons and joysticks (Happ joysticks) for my Street Fighter II cab, which is a Dynamo HS-5. This is just the unboxing and then a fast forward view of the installation of one side. Overall it was very easy to get everything installed, just a little time consuming, but fun!

The joystick hub and the buttons all use the same type of switches. There are three prongs sticking out of each switch. One is for ground, and the other two are used for how you want the switch to activate: when the button is pressed, or when the button is released. So, for the most part, I'm just unscrewing the pieces one or two at a time and then putting the replacements in, and then attaching the two wires to each switch.

The background music in this video is from Dragon's Curse (Wonderboy III: The Dragon's Trap).
