[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.
