If you don't have GH5 working yet, this is the step you are missing!!! ***UPGRADE USB LOADER GX TO CURRENT REVISION 921***
First: Download and Install Hermes' cIOS 222 v4 Installer Choose IOS 249 and then Install Custom IOS 222 and select Use IOS38 merged with IOS37 let installer finish. Then re-run installer and choose IOS 249 again and then custom IOS 223 and select IOS38 merged with IOS60. Let installer finish and go back to the system menu by hitting the home button.
Second: ***Update USB Loader GX To Rev 921 which is the most current revision as of today 3/23/10 check here for the most current revisions. To do this you will have to choose one or both of the following methods: (1) Update USB Loader GX On SD Card or (2) Update USB Loader GX Channel. (note: for some unknown reason, trying to update USB Loader via the update button located in the settings does not work and the program always says no updates found. At least this was the case with mine :o)
(1) Update USB Loader GX On SD Card (update .dol file) To do this download the most current revision here (as of today the most current revision is r921) and copy it to the USB Loader GX folder found in the Apps directory on your SD card. Now delete the existing boot.dol file and rename the r921.dol file to boot.dol. Now load USB Loader GX from homebrew and go to GH5 and choose settings. Now change Load game from IOS 249 to 222 and turn the 002.fix on and you're in business. GH5 will now work on USB Loader GX.
(2) Update USB Loader GX Channel - First delete the existing USB Loader GX Channel if you have one installed. (I'm not going to get in to how to do this... if you don't know how to delete existing channels on the Wii just go to the Wii settings and figure it out.) Now that the channel is deleted, go to your PC and download the r921.wad and put it in the wad folder on your sd card. Now run wad manager 1.5 on your Wii and choose to install the wad you just put in the wad folder. Let the installation finish and go back to the wii menu by hitting the home button. Now you can change the game settings on GH5 to load game from IOS 222 instead of 249 and turn the 002.fix on. Now play the game and rock on!!~ If this helped you please hit my thanks button!:cool:
