The Odroid Go is Odroid´s 10th anniversary DIY kit. Odroid is a South Korean chip company.
The Odroid Go heavily resembles a Game Boy Pocket. It has an LCD screen. The case is semi-transparent, so the inside components can be seen. It uses a 1200 mAh battery. There is a light next to the screen for micro USB charging.
It can run Game Boy, Game Boy Color, NES, and SMS roms through a micro SD card that can be inserted through a slot in the back. The SD card requires beforehand setup, but it does not require flashing.
