Review on Gamilys 512MB Memory Card: The Perfect Wii Gamecube Companion! by Robert Rasmussen

These little things come in handy when you have a lot of games that need to be saved. A save node can hold multiple saves from multiple games, and having four separate nodes makes things a lot better. I recommend getting at least one of these if you have a lot of GameCube games or a lot of saves that take up smaller memory card blocks. However, make sure you turn off the console before switching nodes as this is sure to cause all sorts of problems, just like removing a memory card while the console is still on. This MUST help prevent data corruption.
