I am sure there is no harm in this as I have been doing this for the last few days:
converting a specific wad into a forwarding wad by using showmiiwads pc program and inserting a forwarder dol specific to the program in question.
I have been using wadder.net wiki to find the forwarder dols from their forwarder repository.
Also, I am looking for a wadmanager wad that is version independent and not too flashy. I can insert the wadmanager forwarder dol and make it run the dol from the sd card.
