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 It is no longer maintained.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.

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.

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.
