One of my friends who has his Wii on System Menu 4.3 can't get Riivolution to work properly. Riivo loads, let's him choose from any of the options, but when he tries to load the game, he gets a black screen freeze. Aside from unplugging his wii, he can't turn it off even when holding the power button for seven seconds. Has this happened to anyone else and are there any fixes for it? For myself and two others who updated their Wiis to 4.3, Riivolution 1.04 works. However, his is the exception. Additional Info: (We used a clean XML and files confirmed to be working on multiple Wiis, including my wii.) His wii is a launch-day wii, if that means anything. He has successfully used Riivolution 1.01, 1.02, and 1.03 as well. Upon updating his wii to 4.3, Riivo tried to do something to I0S37, which failed. From there, he upgraded to 1.04, which resulted in the disc being detected, the XML being loaded and from there, a black screen with the disc drive no longer spinning or being read (the blue light also stops.) Note that We used Dop-Mii Wiibrew Edition to delete IOS37, and used Riivolution to reinstall IOS37, as it did ages ago. This resulted in a black screen freeze when loading a game with Riivolution. We did the same thing, installing it through Dop-Mii. This resulted in a black screen freeze when loading a game with Riivolution. We uninstalled, and installed the IOS37 version right under the last. This resulted in a black screen freeze when loading a game with Riivolution. Some more info that may be worth knowing: His wii is a bit laggy in the Menu. His wii's disc drive spins a lot to load things. This currently happens with all games, and it is loud. He sent his Wii into Nintendo, but they did not fix it due to detecting "unauthorized software". I guess we didn't cover our tracks well enough?
