Hermes cIOS (202, 222 and 223)

Although most people use Waninkoko's cIOS36/38, it has some bugs in it. Then came in Hermes and introduced his cIOS, which get installed in the slots 222 & 223. Hermes cIOS fix some of these bugs, so it will increase compatibility. It does not harm the Wii in any to have more than one cIOS. It already has about 70 IOS officially installed so a couple more will only increase compatibility with backups.

Some tests have shown us that putting IOS222 as global boot IOS of your loader has the best compatibility.

IOS222 is the actual cIOS, which we will use with the USB loaders. IOS223 and 224 are exactly the same as IOS222, but it was included with the installer so you could use another installing method (like here by using IOS38 instead of 38 merged with 37) to increase compatibility even further.
IOS202 is used by other homebrew, like MPlayer_CE and some emulators, to read data from USB.

Required
* An SD card (Best results are with non-SDHC cards, SDHC will only work on 4.0 or above) or USB device formatted to FAT(32).
* You must have waninkoko's cIOS installed, or a patched IOS236.

Links (choose 1 of the below)
* cIOS222 Installer v4: http://filetrip.net/file.php?id=8367
* cIOS222 Installer v5: http://filetrip.net/file.php?id=9681
* [Offline] NUS Downloader

Result
* Installs Hermes cIOS222/223/224 for better compatibility.

Guide

The guide now supports v4 and v5. You only need to run one of them, not both (unless you really want to combine them).

Guide

Computer ----------------------


1. Download the cIOS222 installer of your choice and extract it to the apps folder on the SD card/USB device


Wii ----------------------


Version 4

* Unplug ALL Gamecube memory cards and controllers.
2. Run the cIOS222/223 Installer with the HBC. Use IOS249 if it asks so. (If this doesn't work, try IOS236)

We advise you to install the following IOSs with these merges:
  • IOS222 with base IOS38 merged with 37
  • IOS223 with base IOS38
  • IOS202 with base IOS38 merged with 60
The installer will quit after each install, so you'll have to choose it again from the HBC after each install.

2. Run the cIOS222/223 Installer with the HBC. Use IOS249 if it asks so.

We advise you to install the following IOSs with these bases:
  • IOS222 with base IOS38
  • IOS223 with base IOS37
  • IOS224 with base IOS57
  • IOS202 with base IOS60
The installer will quit after each install, so you'll have to choose it again from the HBC after each install.
