Your PC
Dolphin
A wii to dump games from
Some way to put the homebrew channel on the wii
An SD card, formatted to FAT 32 with cleanrip on
A USB storage device or SD card to dump games to. A whole wii game needs more than four Gigabytes, but a Gamecube game uses less, so you could dump GameCube games to the first SD card if it is a 4GB one. If it is a USB drive it is probably simpler to have it NTFS so you don't have to put the dump together afterwards. If it is SD then you are stuck with FAT
A wireless wii bar or a USB converted wired one.
Bluetooth
WiiMotes
any other extensions such as nunchucks.
There are other threads with more details of how to do all of the hard stuff such as putting the homebrew channel on a Wii, dumping games, converting a wii bar to USB and connecting Wiimotes to Bluetooth if they don't work first time. If you struggle binding the component ISOs of Wii dumps to FAT drives then type me in in the search box, as there are some relevant threads which I have contributed to.
