is the sys menus from mod mii homebrew friendly ?
You are going to need to be more specific. It is recommended that you use ModMii when it comes to installing things such as IOS files or upgrading/downgrading your system menu. It does not really matter what system menu you are on. 4.1 is recommended due to the fact that it is the last system menu that offers anything other than homebrew prevention.
