# If your SD card has a private directory, rename it temporarily, e.g. to "privateold". Having other saved channels on the same card will screw it up. (Also, if you don't have any channels on the SD card already, it's possible to skip this step so you can keep saves on your SD card)
# Copy the Bannerbomb "private" folder to the root of your SD card.
# Take your Wii executable, name it "boot.dol" or "boot.elf" if it isn't already, and save it in the root directory of your SD card.
