512 MB of flash memory is more than enough for Wii game saves and Virtual Console. Think of the number of game saves that can be made on the max size 64 MB Playstation 2 memory card. Also take into account the fact that the largest NES, SNES, and N64 games were 256 KB, 4 MB, and 64MB respectively (most were smaller, a very few exceptions were larger)
