![]() ![]() I am also using the extra GPIO pins for the buttons instead of using a USB device like the teensy. I decided not to try to bring out the HDMI port as it would have been very complicated and using a SPI screen the output of the HDMI is the same very low resolution of the built in screen. The battery connector sticks through one of the openings in the battery compartment with some modification to the opening. ![]() the audio on these games are pretty crude anyways. ![]() I will be using the basic PWM out gpio pin for audio. Holds the battery charger circuit and audio amp circuit. Also bridges the required pins from the GPIO to the screen header. Bridges the Connections over to the Cart header for the Mircro SD card. Holds the Pi Zero in a cut out in the middle of the board. Even though i was capable of designing the battery charger and audio amp circuits myself, I took the lazy route and leveraged some readily available designs from Adafruit and copied the Layout and schematics into my project.Ĭustom Button PCB with extra X - Y buttons. What I did is design a set of custom PCBs to replace the original GB PCBs and clean up the project significantly. My project is all working in prototype form except for the audio at this point because i didn't buy an audio amp board for prototyping. I give the user props for a good functioning build, but with my ability to design PCBs and some more knowledge about getting hardware working I set out to build my own. I was inspired by the many Game Boy Zero builds on You Tube, but one in particular where the user used an original Game boy cart to house the micro SD card. I checked all the components for shorts with multimeter, and again all seems to be fine. I have 6 different games and I tried with all of them and the result is as above. Īlso I unsoldered the Game connector, cleaned all the pads, cleaned the connector and re soldered it. With other game the logo disappear after loading, and with another game some times I'm getting "something" on screen that looks like its trying to load the game. With one game I get the logo on the screen and its there until I turn the Gameboy off. its not working, I'm getting the Nintendo logo, the coin sound and that's it, I tried with few different games and I'm getting more or less the same result. So I figured out its about time to check the Gameboy with a game, so as you can guess. ![]() Now there was another issue that there was no sound and no picture, I disassemble it again, checked all the traces and found a damaged trace on the DC converter, I fixed it and then there was sound and picture. The first issue was the leaked batteries that was left in for more than 10 years, I disassembled the Gameboy completely, cleaned all the corrosion, cleaned the shell, put everything back and the Gameboy turn on. Bought a "Not working" DMG - 01 with multiple problems. ![]()
