A project to keep an eye on and help preserve retro games. I know many people maintain a library of these games out of nostalgia or because they're more fun than many current games. There are even devices sold as miniature consoles packed with these games, usually using RetroArch or other libraries. It would be even better if we could maintain these libraries and share them with others who want to play and/or preserve them.
Always good to keep a copy of Pokémon Ruby/Sapphire and Zelda: Ocarina of Time.
I really kind of want a system where each person sets aside N gigs of storage when they join the network and that is transparently used to store blocks of torrents of classic games. It can then be accessed by others over the network. Almost no input needed by the user and massive amounts of storage.
