    Quoted from YeOldPinPlayer:

    Resets from low 5v is a common issue on WPC games. It’s a design weakness. A Kahr board rectifies that design weakness.

    Temporarily.

    Quoted from zhu808:

    Cool - I would love to do this.
    Where do I start?

    Here is what I did for my BSD and CFTBL.

    Focus on step 3 and 4 for to get the power supply hooked up to the game and supplied power from the wall outlet to the power supply you are introducing.

    Like others have said, doing this will supply constant power to whatever extras (ColorDMD for example) you plug into the power supply. To get around that, look at steps 1 and 2 (introduction of power strips with remote "on and off" feature).

    Let me know if you need any further help walking through the process.
