Actually the term "hacking" is incorrect. You homebrew your Wii, which is used to get software not normally available on the Wii. Through homebrew there are cheat code softwares which read codes found online, similar to an action replay; after that you load it on an SD card and let the software read the codes. Nothing to do with hacking into a server.
