I have firmware 4.0u, and I followed and installed everything from this thread: http://gbatemp.net/index.php?showtopic=168890 by deviyl I downloaded some wads and installed them via wad manager 1.5 into the wii. The problem started when the wii didnt have enough memory to hold more wads, so I decided to move them to a 2GB sandisk sd card and run the games from there. I have moved 4 wads and only one can be launched from the sd while the other 3 get a "failure to launch" message. The game that can be launched is "Tales of monkey island - chapter 1", and the games that cant be read are "paper mario ( n64 )", "adventure island the beginning", and "Onslaught". I have done some research and some people say that it maybe an IOS problem. That I need to install a patched version of IOS60 via wad manager. First of all I dont know what is an IOS, and I dont know how to install one. Also some people say that this will lead to a bricked wii, but most of them have that problem with a 4.1+ firmware ( I have just 4.0 ). Where can I find that patched IOS if I have to, and what options should I choose when installing it ( some say I should choose NO when prompted if I want to install the shop channel, etc ... ).
