Frame zoomed in a bit to see the individual horizontal lines. I had the trigger set to wait for the V-Sync signal. Open Bench Logic Sniffer connected to Gameboy DMG-01.Ĭonnected up the Open Bench Logic Sniffer and powered up the Gameboy with a game in it then ran the capture. V-Sync should be 60Hz, Pixel Clock 4Mhz, and H-Sync 9.2kHz. The connector between the front and back of the Gameboy is where I will tap into the signals to sneak a peak. Front board and LCD connector for the Gameboy DMG-01. Kidna like philips heads but with 3 “wings” instead of 4. Needed some cleaning but it worked and had the battery cover! Taking apart the Gameboy DMG-01. Purchased a Gameboy DMG-01 off eBay for $20. I am using a SN74LVC8T245PWR 8-bit directional level shifter to do the translation on the IO wing board.
The Gameboy is a 5V device and the DE0 does not have 5V tolerant IO. I will use the IO wing to level shift the signals from the Gameboy’s LCD screen so my DE0 can capture the data. This is the project that the DE0 Digital IO Wing is for.
