If installed there, discs with 4.2 and 4.3 updates will still ask you to update, even if you are already there. Note that the 249 slot is not actually used in our installation (it was in previous versions of the tutorial). It is also helpful for some people for old games like Twilight Princess.

Definitely use this with Call of Duty: Black Ops. Slot 247 - Base 57 - Compatibility with many games. Definitely use this for games with microphones and Wii Speak. Slot 248 - Base 56 - Compatibility with most games and slightly faster read timing. For maximum compatibility and ease of updating, this tutorial now gives you the following setup: 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. IOS249 can actually be inserted into other slots and we are going to make use of that. For more information about custom IOSes, see the IOSes Explained page. For instance, in order to access a hard drive instead of the disc, an IOS is needed to convert the function calls. The new method can be found here.Ĭustom IOSes such as IOS249 (aka cIOS36, cIOS38 and cIOSx) augment the way the Wii accesses data. IOS249 is no longer used, but instead, d2x.

The new method is simpler, faster and safer to perform.
