Things You'll Need
Instructions
Purchase an SD card that you will be dedicating to playing burned game DVD's on your Wii system. Every time you play these games on your Wii, you'll need to put in this SD card too.
Acquire DVD-R's to use when you are burning games for play on your unlocked Wii.
Download a Wii unlocker application from the Internet onto the SD card. This card will tell the Wii to let you play the non-Wii games. Because every application has slightly different instructions, follow the prompts. Insert your SD card into your computer's dedicated port and save the download files to that card. When you put the card in your Wii, it will unlock the system for you.
