In the latest email from James Bowman he shows the Teensy 4 driving the GD3X. I have tried to hook it up but to no avail. I did try an external 5v supply to the GD3 and did hook up both the 5v and Vin to 5v but the GD3 will not come on. What are the proper pins to use?
The Gameduino doesn't start up at power-on. It needs a sketch loaded on the Teensy in order to start it. Best one to start with is the example "helloworld" - if you load it into the Teensy the Gameduino should start up.

Thank you for your reply James. It turns out that I did have the pins correct. But it still wont come on. I am using a Teensy 4.0, with the newest TeensyDuino version, Arduino 1.8.9, and Gameduino2-v1.2.1.zip library. My GD3 does work with an Arduino Uno so I do not believe that my GD3 is at fault. Can you offer more advice? Thank you.

I wanted to ask, is there a way to use the gameduino3 sd card with the teensy 4.0 and (potentially) with a I2S sound chip Was thinking of making a game for the gameduino but wanted speed, and the teensy is the best thing for that but with little support
Worked this out completely by accident, followed by some trial and error - if I plug in the teensy, nothing happens - if I plug in a teensy while applying some pressure to the left-ish side of the screen, the screen either comes on with just a backlight, or briefly runs the program (fizz), but with various errors / bars on the screen, then displays some form of "Coprocessor exception:" (the error message after varies)
Don't suppose there's an obvious fix for this, or should I contact where I bought it from? (coolcomponents)
