    Its been a while but today I decided to move my ass and get this Famicom build done.
    So before putting everything in place I wired up the Mausberry and ran the Mausberry script.
    I connect all the cables and adapters and move the switch to ON. Pi Zero powers up nicelly and I can play games and do the usual.
    Now I power down the Pi by moving the switch to its OFF position and here is were my trouble starts. When the switch is in OFF mode the Pi keeps rebooting and rebooting in a loop all the time until I move the power switch back to ON and then it shuts down.

    So what the hell did I do wrong?
    Soldered the original Famicom switch to SW + and - and connected the IN and OUT wires to GPIO 23 and 24.
    Is there anything else?

      if you instaled a switch script that is meant for a momentary switch and you have latching switch then that is your problem,
      a momentary switch will only connect the gpio to ground whilst being pushed, then when you push it again it powers the pi, then shuts down etc,

      if you used the original power switch then the script wil see it it as though you have the switch pressed all the time.

        Thanks for your reply and help.
        I am not so savvy with all this switch stuff. I just installed the setup script that Mausberry offers in their install manual so not sure for what kind of switch that script is. A momentary switch is a switch that has 3 pins (only 2 connected) and a non-momentary switch is a switch like an Arcade stick button from Sanwa?

          @FlyingTomahawk an arcade button is a momentary switch. Both mementary and non momentary can have 2-3 pins. On an arcade momentary button you have n.o. and n.c. Normally open and normally closed. If you wire to the normally open then when you press down it activates. Whe it is depressed (pushed up) it activates the normally closed. Some things require a button being detected pressed when you arent pushing it down. Not very common in an arcade to use the nc.

            Thx for explaining.
            So what kind of switch is inside a Famicom? Or SNES?

              @FlyingTomahawk the power switch is non momentary. The reset is a momentary. Momentary meaning it only stays activated for a moment. So anything even like keyboard keys or your controller buttons that are only pressed for a moment and not permanent is a momentary switch.

                So non-momentary switch it is.
                So this script is useless?

                '#!/bin/bash
                
                #this is the GPIO pin connected to the lead on switch labeled OUT
                GPIOpin1=23
                
                #this is the GPIO pin connected to the lead on switch labeled IN
                GPIOpin2=24
                
                echo "$GPIOpin1" > /sys/class/gpio/export
                echo "in" > /sys/class/gpio/gpio$GPIOpin1/direction
                echo "$GPIOpin2" > /sys/class/gpio/export
                echo "out" > /sys/class/gpio/gpio$GPIOpin2/direction
                echo "1" > /sys/class/gpio/gpio$GPIOpin2/value
                while [ 1 = 1 ]; do
                power=$(cat /sys/class/gpio/gpio$GPIOpin1/value)
                if [ $power = 0 ]; then
                sleep 1
                else
                sudo poweroff
                fi
                done

                  @FlyingTomahawk i am assuming that it wont work for you. Im not familiar with the mausberry though.

                    Yeah, script seems to be not working with my current setup.
                    Here pics of the current switch and setup.

                    I also have a PowerBoost 500 which I think can also be used to switch ON/OFF a RPi right?
                    At least it is used here in this Pi Zero in a SNES controller build.

                      UPDATE


                      I tried the Mausberry switch on my RPi 3 this time and who would have thought it does work. So it looks like that the Mausberry or/and Mausberry script won't work with my Pi Zero.
                      Guess I'll have to figure out a different way then.

                        Good to see you're back on the project! I thought maybe a mountain of Gameboys crushed you during a recent trip to Hard-On! ;)

                        You said you have a PowerBoost 500C in the mix. Where is that in the circuit? I don't see it in your photos? I'm pretty sure the Zero in a controller build you linked to is just using the switch to cut power to the Pi. It's not triggering a soft shutdown like the Mausberry is.

                        The switch you have is not a momentary switch. It's a "latching switch" in that you flip it to one position and it stays there. That said, the Mausberry will automatically detect if the switch is a momentary one or a latching one. That's all taken care of in hardware, so the script is not the issue.

                        The script is really just detecting the state of the GPIO pins and when one drops in voltage due to the Mausberry not sending current anymore, it triggers a shutdown command.

                        You said that it works with a Pi 3, so we assume that the Mausberry itself is "good", and while I've not tried one with a Zero, I don't see why it wouldn't work, unless the GPIO pins are either configured differently in your build (I don't think so) or that something is not being detected properly.

                        I'm thinking that the best way to troubleshoot this would be to tweak the script to do something else instead of sudo poweroff or to somehow monitor the state of the GPIO pins. I'm not a programming or hardware wizard, so I'll have to think on it a bit, and it's not quite 7 AM yet.

                        To confirm that your script isn't wonky, this is the working script that I just copied from my Genesis USB hub Pi. Granted, that's with a Pi 3, but still.

                        #!/bin/bash
                        #this is the GPIO pin connected to the lead on switch labeled OUT
                        GPIOpin1=23
                        #this is the GPIO pin connected to the lead on switch labeled IN
                        GPIOpin2=24
                        echo "$GPIOpin1" > /sys/class/gpio/export
                        echo "in" > /sys/class/gpio/gpio$GPIOpin1/direction
                        echo "$GPIOpin2" > /sys/class/gpio/export
                        echo "out" > /sys/class/gpio/gpio$GPIOpin2/direction
                        echo "1" > /sys/class/gpio/gpio$GPIOpin2/value
                        while [ 1 = 1 ]; do
                        power=$(cat /sys/class/gpio/gpio$GPIOpin1/value)
                        if [ $power = 0 ]; then
                        sleep 1
                        else
                        sudo poweroff
                        fi
                        done

                        I really think it's a matter of the GPIO not being detected properly, not that the Mausberry is being weird.

                          Well if the mausberry can detect the difference between momentary and non momentary then we should assume thats not the problem, then if the pi3 works fine witht he same switch, it would seem likely that the zero isnt maintaining the same logic on the gpio when its off as the pi3.

                          as most of these things work by shorting a pin to ground, you may want to take a digital multi meter and make sure that the pin on the pi zero stays shorted to ground when its powered off.

                            N64 emulation is the next step :)

                              Hey! It is so good to see that you are still around.
                              Yeah, I totally neglected this build. I guess waiting over 2 months for the Mausberry killed it. I kept working on my Futura theme and also got into other things like eGPU stuff.
                              Got me a GTX660 and connected it to my Laptop and now I started to replay all the games I could never play on Ultra settings. Skyrim, Sniper Elite V2, Mass Effect 1-3 I tell you gaming can be sooooo time consuming.

                              Anyways, back on topic.
                              I am not sure what exactly went wrong. As you guys say the Mausberry works with the RPi 3. I will try to solder the GPIO pins tomorrow so that I can just plug in the two cables that came with the Mausberry. Maybe my soldering work was not good?
                              Still I didn't wanna stop there and leave the stuff otherwise I might not continue to work on it again. So I took all my parts and start to put them into the Famicom and here is the result. She ain't a beauty but it does work and besides I still got a few more Famicoms here to improve. The controllers can only be charged if the Pi is running. Wish there was a sleep mode like the PS4 has where you can keep charging the controllers. Here pics....

                                          It's a Sharp TV. We have 2 Sharp TVs and both can display that clock on the bottom-right.
