NASA is reporting that countless of unlicensed (I hope) alien early videogame ROMs are being streamed in space as we speak.
METAME is a Multiple ExtraTerrestrial Arcade Machine Emulator and it's probably the first opensource earthling attempt on emulating extraterrestrial videogame systems.
Since the amount of available games is hard to manage, METAME will download a random game and play it. To save a game just add it to your browser bookmarks - however game indexes may change during development.
This emulator is far from being complete and alien gaming experiences are mostly obscure and scary. It may result in a both inspiring and disturbing experience to you. Play it at your own risk.
METAME uses arrow keys as general motion input and Z button as alternate action. Tested on Firefox and Chrome desktop. - Contact me
