  • RasberryPi + Jamma

    Hi folks, I have a TMNT 4 player cabinet and want to add to the games I am able to play on it. I am thinking about getting a pi + Jamma to do this.

    Before I dive in, keen on peoples thoughts and experiences in doing so. will it work out or am i better off investing in original PCB's ?

    Youll save a tonne of money. Tmnt, turtles in time, simpsons.. all pricey boards. I also would imagine itd be more reliable than older original boards

    if i didnt already have tmnt and turtles in time, id consider it too for my 4p cab.

    I cant speak for 4 player version of this kit, but i do have an arpicade on my 2 player cab with all the konami titles and its brilliant. Should hit up dee2er user on here, top fella

    Best of luck

        We used the 4p setup recently. Worked well once configured.

          Yep, once we got the config sorted the 4-player rasp-jamma was great. Would definitely recommend.

            awesome thanks all. Will try it out. I have a pi, any recommendations on sourcing the Jamma adapter locally?

              Ok, just clicked on the dee2eR and clearly this is the place to start

                dee2eR will sell you everything you require. He's the original creator of the product and also provides a shitload of continuing support.

                  That's right. Excellent support. He helped us immensely getting the 4p adapter configured.

                    Also replied to your PM. Was a bit slow to this thread.

                    The RaspberryJAMMA + four player adaptor should be plug and play in your TMNT cab. The software side of things will take a little bit of fiddling though to suit the lack of start buttons on that cab. I'll be happy to help if you need any if/when you go this route. For more info check out the RaspberryJAMMA bit in the sponsors section here on AA or have a look at the arpicade.com forums (the main page of the arpicade.com site is out of date...).

                    I'm as local as you'l find it (Melbourne), the boards are both Australian made.

                    Thanks to everyone for recommending me.

                      All arrived (super fast!) and on the setup path. Thanks Dylan!

                        Excellent. Got a multimeter? First thing I had to do when I used the pi is ramp up the 5v on my psu. There was a big voltage drop when the pi was powered. My PSU was measuring 5.1 at the harness with no load and then with the pi running it would drop to 4.8.

                        This meant that the pi was undervolted and running slowly. The pi will warn you of this with a lightning bolt in the top right hand corner of the screen. I had to put the pi on and then adjust the PSU while it was under load. The pi can happily take up to 5.2v, so I set mine to 5.1 when powered and it worked fine.

                          Yes I do so will take a look. Is it possible to power the Pi separately to help resolve this?

                          Where on the Pi did you check the voltage from?

                            You can get a separate psu to power it, but one of the good things about the pijamma is that it can be powered over the 5v on the jamma with no additional hardware.

                            Check the voltage at the 5V Jamma edge connector when the pi is running, that's the easiest way. I also expect that the pi itself would likely have a test point somewhere on it that you can poke with a meter.

                            If when you boot it, you get the lightning bolt, you'll have to up the voltage.
