You don't need to do this. I bought a 1TB sd card because I heard that was enough space to store every retro game up to n64. I ended up copying over a small hand-picked selection of games rather than the full romset. We need some people to keep copies of the full romsets for the sake of preservation, but typical users only want certain, popular games.
