I solved it by myself
I figured out, that the control input was not possible because it seems the mode button is pushed permanently.
I checked the connection from the mode button/on-off switch board to the back board and there was the mode pin wich was bended to ground.

I need more information, the circuitry on the circuit sword is completely different to the SAIO so it will not be the same. Could you let me know what happens and in what conditions.. e.g. with/without battery/usb.. please describe in your own words When i power up (with/or without battery is conne...

I've got the same problem with the button input like JCDenton5 description in the first post under No.2
But i have the Circuit Sword instead.
Maybe the same issue with this transistor?
Is there any chance to check this by myself or is it necessary to send the board back?

I want to add a 2nd Thumbstick in my built because of using it as the yellow C-Buttons for N64. After doing the calibration sequence, the 1st one is working. But there is no function on the 2nd one. I tried to replace number one with number two but only the tumbstick which is connected in the JOY1 J...

Can you please share the Arduino code for using a game controller with 2 joysticks like you do in your build?

Did you make the onboard usb hub work on this Helder board? I've tried it a few month ago and it doesn't work for me so i used a external usb hub instead. I disassembled the gamboy zero, because it wasn't perfect to me. Now, after a few month, i want to reassemble the gamboy zero and i hope to get t...

I have a problem with the Power Monitor. When Retropie boots up the Power Monitor starts directly after the Retropie Logo is shown. No matter if i plug in a extern Charger the Power Monitor will start when booting up the raspi. My battery is fully charged (4,17V). I even trie to bridge B+ and PP1 to...

I want to program the AIO PCB with the new controller sketches. But i get this error code while uploading: ...Desktop\Arduino\GBZ_Controller\NoAnalog\Gameboy.hex\Gameboy.hex.ino:1:21: fatal error: Gamepad.h: No such file or directory#include <Gamepad.h>^compilation terminated.exit status 1 Is this b...

I have this random joystick movements. First i connected a PSP Thumpstick and i had the random movements issue. Than i programmed the board with the ne no analog code and grounded the x and y axis but the movements are still there. It's very frustrating. Hope to fix this problem with some help from ...

I like the idea with the 3 position switch. So the battery don't drain when everything switched off. I also use the alternative power boost. Do you have a link for this switch? I can't see in the part list.
