I am also getting the green screen after doing this ------------------>
a). Open the Homebrew Channel and load Preloader, press 1 to install. After install, your Wii should reboot and load the Preloader menu. If it doesn't, turn your wii off and on again whilst holding down reset and it will load the Preloader menu.
b) Select 'system hacks' in the Preloader menu, and enable all the hacks in the list. Select 'save settings' and wait for confirmation message to display 'settings saved'. Press B to go back, and enter Settings. Set 'Autoboot: System Menu' using D-Pad, then select save settings. Press B to return to main Preloader menu.
c) In the Preloader menu select Homebrew Channel, run Wad Manager 1.4 and install these wads:
IOS38-64-v3610
IOS53-64-v4113
IOS55-64-v4633
Backup Launcher-WBKL
Then restart your Wii.
d) Open Homebrew channel again, run cIOS38 rev14 Installer and select Wad install.
All done! You will now have the safety/hacks of Preloader, NeoGamma R6 backup loader that has 99% compatibility, cIOS249r13a and IOS38, 53 & 55 for newer games.
