That's not true.The Wii has 512MB of flash memory build into it and this storage space an be used, amongst other things, to store your Virtual Console games. In their original forms this memory would allow you to store in the region of 8 N64 games, 170 SNES, PC Engine or Genesis games or over 1,000 NES games. Modern compression techniques can make these games even smaller meaning that 512MB will be more than enough space. If you run out of internal memory space then you can save information on memory cards. Wii memory cards come in the form of SD cards simular to mobile phone memory cards. How much memory you want is entirely down to how much money you want to spend, but most people won't need huge cards so they won't spend much.Originally Posted by Mr_Stoukaph
The source of all that info came from Official Nintendo Magizine (UK). So its reliable.
