All, First I want to say that I searched the site and couldn't find any threads referring to this issue. My Wii specs: FW: 3.4u Modchip:Yaosm I haven't tried any of the newer games until NSMB came out and have figured out that I need a cios and neogamma to run it on a chipped Wii. I got it to work, mostly. My question is regarding the cios installation. I downloaded cios rev14 and followed the instructions(mostly) and everything seemed to go ok, however I noticed that on the cios installation menu that I did not have cios249 as an available selection in the menu but only had cios numbers available in the range of between lower 30's to 55. I did not have cios249 available as was showing in the installer instructions before you run it. I ended up leaving it at the default of cios36. Now when I run neogamma, it complains that I don't have cios249 installed and asks if I want to continue. I do continue and am able to launch and play NSMB with no issues. I have read a bit about cios and what I have read concerns me that I installed rev14 as cios36, that it could brick my wii if I wanted to remove/change it. So my first question is, do I need to uninstall the cios to get a cio249 version? can I do it safely? Once uninstalled, how would I get the cios249 option to become available? Thanks.
