Sega Master System Controller Pause Button Mod Kit

The Sega Master System is a fun console but Sega did not include a pause button on the controller, instead they put one on the console itself. Many games require pausing to access the game inventories and because of this lack of an easy access pause button it can often make what should be a fun experience into a bit of a chore. Did you know you can turn on the ring you collect in Alex Kidd in Miracle World and shoot stuff? makes for a much more fun experience. This kit allows you to access the important in game menus with your controller to vastly improve the Master System gaming experience.

Up until now the only way to install the pause button into the controller was to do a messy deadbug install with no real way of making sure the switch hole was positioned well.

My kit makes the install a breeze.

Dual Pause Board

The Dual Pause board has everything needed to control the pause button via two controllers and it installs on the bottom of the Master System mainboard with pads placed for easy wiring.

Controller Switch Board

The controller switch boards do two things. They house the components to make the pause button work via an impossible button combination and they double as drill templates for cutting the switch holes.

With these boards the switch installs will be perfect and repeatable every time.

How does it work?

It uses a switch to activate two buttons from the D-Pad called an impossible button combination such as up and down together. This impossible button combination is ignored in software and accepted by a logic gate which then grounds the console’s real pause button.

For more info on how it works please read the install guide.

    I absolutely love this kit! Really adds something that was missing to the OEM controller. I can’t believe how cheap this kit is either, because it’s clearly good quality, and made by someone who loves the retro gaming hobby.

    Was super easy to install using the incredibly easy to follow install guide provided.
