This guide will help you disassemble your Sega Genesis II 6-button controller. You will need a Phillips #00 screwdriver to complete this guide.

This specific model was released in 1992/93, at the same time as the Sega Genesis II. However, it is also compatible with the Sega Genesis I.

Step 1 :: Disassembling the handle

• Flip the controller upside down.
• Using a Phillips #00 screwdriver, remove the five screws holding the controller back cover in place.

• Then remove the back cover of the controller, which gives you access to the motherboard of the controller.
• NOTE: Carefully put back the 5 screws from step 1 as well as the back cover of the controller.

Step 3 :: Disassembling the motherboard

• Then remove the 8 plastic buttons.

Step 5 :: Dismantling the Directional Pad
