The Wii Shop is stupid. I was trying to download a game, Gradius, which I had (barely) enough blocks to fit on my Wii and then it tells me it requires 92 blocks, more than 4 times what it actually needs, and because I don't have that much space I can't download it. This resulted in about 45 minutes of deleting and redownloadinng VC games in order to make everything fit, made increasingly longer by my unknowingly deleting games (such as Ice Hockey, Super Mario Bros., A Link to the Past, and Sonic 2) that also require significantly more blocks to download than they actually take up on the Wii.
