Game Boy VGA using an FPGA

[ViDAR] was looking for a project to keep him occupied and settled on creating a VGA converter for his Game Boy. He had some difficulty finding pinouts for the LCD and CPU but working with what was known, and an oscilloscope, he found the necessary signal. Tap into just a few lines using those thin blue wires; Vsync, Hsync, clock, and two data pins. From there a development board with an Altera Cyclone II field-programmable gate array takes care of the heavy lifting. The board already has hardware for a VGA connection so it was just a matter of processing the incoming signals into the VGA standard. His demo video is embedded after the page break.

Original shell houses a Game Boy Advance SP

[Jackson] decided he wanted to give his original Game Boy a bit more power so he replace the internals with those from a Game Boy Advance SP. This keeps the case work to a minimum, as the original was larger than the SP. He kept the buttons, speaker, headphone jack, and power switch but modified the enclosure to use the volume, charger, and battery from the newer hardware. The cartridge connector was relocated to match the slot in the back half of the case, with the color screen being the biggest giveaway that someone’s monkeyed with the device. Not a bad use for a dead Game Boy, as least you’ll be playing this one instead of dedicating it to virtual storage.
