The older games, the ones from the older consoles take up the least amount of blocks. Its generally the n64 ones that take up the most space of them all. But don't worry, like other members I have played and downloaded several games and have well over 800 blocks of memory left. Memory is not an issue.Originally Posted by zap'em up
Although, keep in mind if want to play Gamecube games you need a Gamecube memory card to save your data for those games, they don't save to the Wii's memory. Which is good in a way, it saves your Wii memory.
