awesomer shop | Deals | handhelds | retro
There are lots of handheld retro game systems, but the GameShell offers far more versatility than others. In addition to playing emulators for Atari, GB, GBA, NES, MAME, MD, PS1, and more, its modular construction and GNU/LINUX-based dev kit encourages you hack and modify to your liking. Some assembly required.
