Wii - D2X Cios v8 Final.

D2X Cios is a custom IOS for the Wii console, i.e. an IOS modified to add some new features not available in the official IOS. This Cios has been made to be used ONLY with homebrew software.

D2x 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. d2x replaces the now obsolete IOS249.. The d2x cIOS is an enhanced version of the cIOSX rev21 by Waninkoko.

The prime reason you want to install d2x is for the IOS reload blocking. This makes virtually all games compatible with later versions of Configurable Usb Loader. Metroid Prime Trilogy was the most popular of these games that didn't work before but does now.

Feature Supported:

• Support IOS bases: IOS37 v5662, IOS38 v4123, IOS53 v5662, IOS55 v5662, IOS56 v5661, IOS57 v5918, IOS58 v6175.
• Installation slot support (200 --> 255 except slots 202, 222, 223, 224, 242 and 254).
• Online and offline installation (WAD Manager support).
• SD and USB devices support.
• Classic controllers, Wiimotes and Game Cube pads support.
• Support Ios=xxx version in the meta.xml file to fix the IOS used by d2x cIOS installer (only active without AHBPROT).
• Option to select the cIOS revision, Batch installation support.
• Module to save/load an installation config file.
• Module to save a NUS script.
• Uninstall cIOS feature restricted to the slots 200+.

D2x can actually be inserted into many/any slots, these versions (v8) 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.

Note that the 249 slot is not actually used in d2x installation. This is the most common slot you will see in other tutorials (and it used to be used in this tutorial). However, if installed there, discs with 4.2 and 4.3 updates will still ask you to update, even if you are already there. Installing to the alternate slots means you can still play your discs without them messing up your USB Loading setup!

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.

Introduction.
What you need..?

• Homebrew Channel installed.
• IOS236 installed.
• SD Card / USB Flash drive.

NOTE: D2X Cios Installer v3.0 is currently not recommended.. If your Wii is not connected to the Internet, you need to use NUS Downloader to get the following files:

• Download IOS56 v5661 with Title ID 0000000100000038 with the Pack WAD option switched on to get IOS56-64-v5661.wad.
• Download IOS57 v5918 with Title ID 0000000100000039 with the Pack WAD option switched on to get IOS57-64-v5918.wad.

You can install d2x cIOS through ModMii or d2x-cIOS-installer. The easiest way is the installer. It installs the cIOS directly, so a WAD Manager is not needed. The installer uses the IOS bases from SD/USB (you can get them via NUS Downloader).

ModMii is really good too, but you need Windows to use it. Once you have the wad you can install them with a WAD Manager. The recommended configuration: 249 base 56, 250 base 57.
