I have a few versions of new Super mario bros. and so far there are two versions I cannot add for the life of me to my HDD for usb loader to play: NSMB 3 The Third Level (shows up as NSMB 2 the next level) and DU Super Mario 2.1 madness returns (also shows up as NSMB 2 the next level) and of course I already have the NSMb 2, so how do I add these? and is it still possible to get the covers if i change anything? am simi-new to this soft-modded wii. any help/input you can give would be great! thanks.
