    I’m using a PSX shell for my build, but don’t want to shell out any money for a Mausberry circuit. Using the existing power switch from the PSX board, I can just make it ‘interrupt’ +5volt on my usb power cable, and use it’s ‘off’ position to break the +5 with no issues right?

    *RPI2 Model B+
    *5v 2a usb power

    I don’t care about sending a ‘quit’ message to the Pi2, I am ok with manually shutting down before killing the power. Anyone else doing this instead of adding on a Mausberry? Reset function not important, I won’t use it.

    You will end up with problems with your SD card, trust me. I’ve killed a few that way. However, you don’t need a mausberry circuit if you have a soldering iron.

    This works well:

    Ya, you don’t want to just cut power repeatedly.

    I’m currently using the original power switch from the PS1 shell I built into a PI2. I have it interrupting +5 to kill power to the board and a secondary power LED.

    If I send term signal through retropie, and shutdown everything so that it’s in an ‘off’ state but still powered, how is this any worse than a mausberry killing the power? (Honest question) I have been using it like this for about a week now.

    It’s not, assuming you do it that way.
