IOS249

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 It is no longer maintained.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 simpler, faster and safer to perform. IOS249 is no longer used, but instead, d2x. 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.

READ THIS FIRST

IOS249 can actually be inserted into other slots and we are going to make use of that. There are also different versions of IOS249 that can be installed into any of the slots and these versions are determined by the base IOS used. For maximum compatibility and ease of updating, this tutorial now gives you the following setup:

Slot 248 - Base 56 - Compatibility with most games and slightly faster read timing. Definitely use this for games with microphones and Wii Speak.
Slot 247 - Base 57 - Compatibility with many games. Definitely use this with Call of Duty: Black Ops. It is also helpful for some people for old games like Twilight Princess.

Note that the 249 slot is not actually used in our installation (it was in previous versions of the tutorial). If installed there, discs with 4.2 and 4.3 updates will still ask you to update, even if you are already there. This makes things slightly easier.

Using these slots means that you must also do the meta.xml steps of the USB Loader instructions.

Feel free to experiment with other slots and bases. They won't hurt your Wii and you can reinstall any base over any slot at any time.

What you should install first

What you need

  • SD Card

What to download

  • Waninkoko's cIOSX rev 20 via this page.
  • If your Wii is not connected to the Internet, you need to get NUS Downloader from this page on your PC then (using the Pack->WAD option and renaming the file to the specified name):
    • Use it to download Title "0000000100000038 v5661" to get IOS56-64-v5661.wad.
    • Use it to download Title "0000000100000039 v5918" to get IOS57-64-v5918.wad.

Installation procedure

  1. Unzip the zip file and copy the contents (the cIOSX_rev20b-Installer directory) to sd:/apps
    • Thus, you should now have a file called sd:/apps/cIOSX_rev20b-Installer/boot.dol
  2. If your Wii is not connected to the Internet, copy IOS56-64-v5661.wad and IOS57-64-v5918.wad to sd:/
  3. Mute or lower volume of your speakers (the installer has loud music)
  4. Insert the SD card in your Wii and start Homebrew Channel then the "cIOSX_rev20b-Installer" app
  5. Choose IOS236 for the IOS to use for the installation
    • If you have a different cIOS already installed, you could choose that here instead.
    • If you don't have IOS236, then pay more attention to the "What you should install first" section above.
  6. Push A to accept the disclaimer
  7. We are now going to install IOS248 with base 56 using the following substeps:
    1. Select IOS56 v5661 for the base IOS version with D-pad left/right and push A
    2. Select IOS248 for the Custom IOS Installation Slot with D-pad left/right and push A
    3. With the D-pad, select network installation if you are connected to the Internet or WAD installation if not, and push A
      • If your Wii is not connected to the Internet, you will also have to choose the SD card as the source for the WAD
    4. Let the installation complete
    5. Press any button to go back to the menu
  8. We are now going to install IOS247 with base 57 using the following substeps:
    1. Select IOS57 v5918 for the base IOS version with D-pad left/right and push A
    2. Select IOS247 for the Custom IOS Installation Slot with D-pad left/right and push A
    3. With the D-pad, select network installation if you are connected to the Internet or WAD installation if not, and push A
      • If your Wii is not connected to the Internet, you will also have to choose the SD card as the source for the WAD
    4. Let the installation complete
    5. Press any button to go back to the menu
  9. Press B to exit
  10. You have installed IOS249 into the 248 and 247 slots and can now move on with other steps in the tutorial.

Updating or reinstalling IOS249

In order to update or reinstall IOS249, just do these steps again. Also, if you haven't done so before, perform the meta.xml steps of the USB Loader page as they are required for this IOS setup.

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

  • What are the other bases/IOS slots for?
    • Some of them might have better compatibility on future games. For now, base 56 and 57 are the only versions you need.
  • How do I reinstall a different version of IOS249?
    • Just follow the procedure again.
  • 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 or here to see the old methods.
  • 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.
  • The current rev 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.
  • Configurable USB Loader is giving me an error stating IOS249 is a stub. What's wrong?
