#RASPBERRY PI GAMEBOY ADVANCE EMULATOR DRIVER#
It has a detached control button bar which results in a smaller driver board. My display is a newer generation (in comparison to the other versions when you google for TaoTronics 3.5). Leave the four wires on the PCB, detach the whole unit from the main PCB.
Recycle Gameboy partsĭon't throw away the inner Gameboy stuff! Rather desolder the power connector (it's a connector with 3mm outer and 1,2mm inner diameter), speaker and the audio connector PCB. Clean the cover if necessary (I used a pressure washer to speed it up). Clean the buttons and the pads, if necessary. Afterwards clean the case (front, back and the battery cover). Remove the battery connectors from the case - you won't need them anymore. So don't throw away the inner Gameboy stuff! Peel of the display cover put all buttons and the button pads aside. I reused parts of the Gameboy like the audio adapter, the power connector and the speaker and some screws. Open the Gameboy case and unscrew everything in the case. This order is much faster and efficient than I did it in the first place. After that, I started to work on the case. I tried to solder all the components at first together to see whether they work together (audio, video).
The order of steps is not the one I used. I also had some smaller stuff which I used to assemble the RaspiBoy. The Common Ground DMG PCB took the most time for shipping (I ordered it from Germany in the USA). In order to run the Gameboy I used a switching power supply. Only few components more are needed: The Common Ground DMG PCB (for connecting the controller/buttons), an audio amplifier (I had one already from previous projects) and some additional buttons. Model B would be sufficient, but B+ is much handier and fits like a glove. On the other side, FBAS/Composite was merged in the audio port. Model B+ has more USB, more GPIO and improved audio. Lucky me: At that time Raspberry Pi B+ model was released. I could also not find a 3.5" display that accepts HDMI or DVI/DisplayPort.
In the end, it seemed to me that you need a display and a driver PCB which controls the display. Raspberries have a DSI display connector, but it was quite complicated for me to find a DSI display. The picture gets fuzzy especially at the borders. There is always some noise because the signals are analog and not digital. The connection to the display is FBAS/Composite - one of the cons. A 3.5" screen will leave some 5 millimeters space in the case. The maximal display size which fits the case is about 3.5" (about 89 millimeters) in diagonal. The original Gameboy screen has a size of 2,66" (which is about 66 millimeters). Gameboys with broken controls are worthless. The case should not be damaged, the buttons and their pads should work. I decided to take one which is not too yellow (). There are some cheap offers with broken Gameboys. Most of them sell complete sets with tons of cartridges. There are plenty of sellers on Amazon and eBay.
