IOS249 (OBSOLETE)

Installing Waninkoko's IOS249 for use with USB Loader

Warning: This is the old version of this page kept for posterity. It is no longer maintained. The new method is easier to understand and less prone to error. The version on this page also contains a broken link to AnyTitle Deleter Mod. The new method can be found here.

Custom IOSes such as IOS249 (aka cIOS36, cIOS38 and cIOSx) augment the way the Wii accesses data. For instance, in order to access a hard drive instead of the disc, an IOS is needed to convert the function calls. For more information about custom IOSes, see the IOSes Explained page.

Information Needed

The installation method of IOS 249 is different depending on your Wii's specific setup. Please expand the appropriate section to get further instructions based on your setup. Note also that you do not need to expand any sections if you have installed IOS249 in the past. In this case, see the Updating IOS249 to a Different Version section below for instructions instead.

What we need to know is your Wii's firmware version.

Now, follow the appropriate instructions for your Wii according to the following statements, followed by the steps needed by all Wiis when prompted. Note that at one stage you will be asked to remember something for later. Do so.

I am on a firmware version of 4.2, updated via Nintendo's official upgrade process

I am on a firmware version 3.3 through 4.1, or I updated to 4.2 via the Safe 4.2 Upgrade Methods (Methods 2 or 3 only) or similar homebrew applications.

I am on firmware version 3.2 or less

Follow the Steps needed by all Wiis below and remember that you need to choose the default IOS chosen by the installer later when asked.

    • A direct link to the rev 19 file is here.

    • Use it to download Title "0000000100000039 v5661" to get IOS57-64-v5661.wad.

  2. Unzip cIOSX_rev19-Installer.dol and copy it to sd:/apps/ios249

    • If you came here from the steps for 4.2 Wiis updated by Nintendo, use IOS236

    • If you are updating IOS249 (i.e., this is not your first install) and you have not upgraded to firmware 4.2 since the last install, select IOS249.
    • If you are updating IOS249 (i.e., this is not your first install) and you have upgraded to firmware 4.2 since the last install, select IOS250.
    • If your Wii is 3.2 or less, use the default IOS chosen by the app

Updating IOS249 to a different version

Perform these steps if you want to install a newer revision of IOS249 or need to reinstall it for whatever reason.

If you have not updated your Wii to 4.2 via the official Nintendo update, then go to the section titled Steps needed by all Wiis, after performing any needed steps above. remembering to choose IOS249 later when asked. There should be no need to do the earlier steps again as long as your IOS249 currently installed is still intact.

If you have updated to 4.2 since installing IOS249, then use AnyTitle Deleter Mod v6b from this page and perform the following steps:

  1. Remove all GameCube memory cards and controllers.
    • This step is very important. Do not ignore it .
  2. Create the folder sd:/apps/ATDM/
  3. Unrar mod6b.rar and copy boot.dol to sd:/apps/ATDM/
  4. Run apps/ATDM/boot.dol from the Homebrew Channel
  5. Select IOS250 as the IOS to start and push A to confirm.
  6. Navigate to "System Titles" and push A to confirm
  7. Select "IOS222" and push A to delete then A again to confirm.
  8. Select "IOS223" and push A to delete then A again to confirm.
  9. Select "IOS249" and push A to delete then A again to confirm.
  10. Push Home to exit AnyTitle Deleter Mod
  11. Now follow the Steps for all Wiis listed above and remember to choose IOS250 later when asked.

If that procedure doesn't work, then just start the tutorial as if you didn't have IOS249 beforehand. It's perfectly safe to do so.

Something went wrong. What do I do?

  • Don't panic. Make a backup of your Wii with BootMii if you are scared.
  • Ensure you followed the instruction fully and placed files where you were told to put them. Do not assume anything.
  • Some people have reported issues with network installation starting, but not completing correctly. If your errors are occurring with network installs, try the non-network method.

FAQ

  • How do I reinstall a different version of IOS249?
    • Just follow the procedure again. You should only need to repeat the final steps, even if you have changed firware in the meantime.
  • This method looks a lot different to the one I used before, what gives?
    • This new method is simpler, easier, faster and safer. Go here to see the old method.
  • Is this method safe for LU64/65 Wiis? I thought they needed a special procedure.
    • Yes it is safe. They used to require a special procedure which is now obsolete. Go here to see the old method.
  • I am using rev 13 of IOS249 and every second game I play seems to crash during loading. What's wrong?
    • This is a known bug with rev 13. Rev 14 and onwards correct the bug. If you wish to stay with rev 13, do not use the "Wii Menu" function on the Home menu to exit your games. Instead, use the reset option, or hold the power buttton on the Wii Remote to restart the console between playing different games.
  • Super Smash Bros. Brawl keeps crashing.
    • Dual layer games are buggy in rev 14 and rev 16. Try using rev 17 or Hermes' IOS222/223 to reinstall and play the game.
  • I can't play Metroid Prime 3 within Metroid Prime Trilogy, even with the alternate .dol method.
    • Dual layer games are buggy in rev 14 and rev 16. Try using rev 17 or Hermes' IOS222/223 to reinstall and play the game.
  • Rev 15 isn't working for me, but rev 10 worked fine. What's up?
    • You are probably using the wrong USB port. From Rev 12 onwards, the USB drives for USB Loaders must be plugged into the USB port closer to the edge of the Wii.
