Hermes' IOS222 and 223 are alternatives to using Waninkoko's IOS249. There are some compatibility differences that may make you wish to try these instead of IOS249. It is suggested you try IOS249 first, and try these if that fails.

The installation method of Hermes' IOS 222/223 is different depending on your Wii's specific setup. Please expand the appropriate section to get further instructions based on your setup. If you have already performed the necessary changes to your system (e.g. for IOS249) and you have not updated your Wii in the meantime, you can skip the appropriate steps.
What we need to know is your Wii's firmware version and your Wii's serial number.
Now, select the category that refers to you and follow those instructions:
I am on version 4.0 or greater and my Wii's serial number does not start with LU64 or greater.
I am on version 4.0 or greater and my Wii's serial number does start with LU64 or greater.
I am on firmware version 3.4 or less OR I have already completed the steps for my Wii listed above
Once you have IOS222/223 installed, you can use a USB Loader.
