So all you need is the original NSMBW iso, the Patch Files, and the iso Builder. This method is for Soft Modded Wii's so you can burn the NewER iso or USB load a wbfs. There is another method for unmodded Wii's which I'm not familiar with.
The NewER game has a different ID so it will not overwrite your old game saves.
