The miniature Game Boy Color prefix, the creation of the Dutch programmer Jorun Domburg, practically does not occupy a precious place, since it can be hung on a bunch of keys as a key fob, and used for its intended purpose, that is, play wherever your heart desires. The enthusiast managed to pick up the components and improve the GNUboy emulator in order to finally get such a small but working console. The product is equipped with a 1-inch OLED display with a resolution of 96×64 pixels, a dual-core chipset with a clock frequency of 240 MHz, 512 KB of RAM and 4 MB of internal memory, Wi-Fi and Bluetooth modules, a speaker, a 150 mAh battery and a plastic case with operation buttons and crosspiece. Due to the poor technical stuffing and the small amount of space on the Game Boy Color, only a few emulations can be recorded. Downloading is carried out from any PC or smartphone via Wi-Fi. The programmer demonstrated the capabilities of the miniature set-top box by launching Tetris, Super Mario, DOOM and Witcher 3 on it.
