Items you will need

  • Wireless home network

  • Two memory cards

  • Memory card reader

The Nintendo Wii does not allow you to play copies of Wii games unless you have modified the operating system first, either through software or the inclusion of a computer chip. You can play a copy of a Wii game that has been converted into a file in the ISO-format on a modified Wii, once you have downloaded free Wii ISO modification programs on a computer and have added them to the Wii. You can then put the ISO file onto a memory card. The Wii will read the ISO file from the memory card once you have inserted it into the Wii and treat it as if it were the original game disc.

Modifications Made On A Computer

Download a Wii ISO cover modification program, for example, the WiiCoverfloater program; a Wii ISO media program, for example, the Wii ISO MediaFire program; and a Wii ISO media managing program, for example, the Wii ISO Media Manager (see the links in Resources).

Double-click on the three files once they have downloaded to decompress them to folders on the desktop.

Insert a memory card into the slot in the memory card reader. Plug the memory card reader’s USB cable into a USB port on the computer.

Double-click on the icon of the memory card when it appears on the desktop to open its window.

Double-click on the Wii ISO Cover modification folder to open its window. Drag the lone file inside of the folder into the “WAD“ folder inside the memory card’s window.

Drag the lone folder that was next to the lone file into the “Apps” folder inside the Wii ISO Cover modification folder.

Double-click on the Wii ISO Media folder on the desktop to open its window. Double-click on the “CIOS36_revken Installer” folder to open its window.

Rename the only file that is not a “readme” file inside the window to “Boot.dol” without the quotes.

Double-click on the “Apps” folder inside the memory card window to open its window.

Right-click inside the window. Select “New folder" from the pop-up menu. Name the new folder “CIOS36Rev10" without the quotes.

Repeat this procedure to make a folder called “WADmanager1.4.”

Copy the “Boot.dol” file into the “CIOS36Rev10“ folder.

Double-click on the Wii ISO Media Manage folder to open its window.

Rename the only file that ends in “.dol” into “Boot.dol” without the quotes.

Copy the file into the “WADManager1.4” folder that is in the “Apps” folder.

Right-click on the icon of the memory card. Select “Eject” from the pop-up menu. Remove the memory card reader’s cable from the USB port of the computer. Remove the memory card from the slot in the memory card reader.

Insert the other memory card into the slot in the memory card reader. Wait for the icon of the memory card to appear on the desktop.

Drag an ISO Wii game backup file onto the icon of the memory card. Wait as the ISO Wii game backup file copies to the memory card.

Right-click on the icon of the memory card. Select “Eject” from the pop-up menu.

Remove the memory card reader’s cable from the USB port of the computer. Remove the memory card from the slot in the memory card reader.

Tip

  • A Wii that is modded through software, not a computer chip, can be restored to its original state without having to open it up.

Tip

  • Inexpensive memory cards are made of inferior materials and can fail to work properly when inserted into the Wii. Modifying a Wii voids the Nintendo warranty.
