I don't have a working Wii (haven't for five years). I got into Dolphin and that works good so far, even got the system menu loaded, but Mega Man 9 and 10 have DLC and those do not load at all.

Their in the system memory on that menu but if I load either of them, they don't have the dlc, either from the menu or loading the .wad.

I haven't found anything that says its possible to load the dlc without having the full Nand, but details on that are rough to find, plus my Wii doesn't work, and the shop channel died so I can't even dump the DLC either.
