This Is One Of The Newest Roms Released, So I Decided To Release This Save File On To Gbatemp! I Hope All Will Enjoy It!P.S. This Is A Japan Save File!
I don't have a wii u anymore to test it myself, but if homebrews are not visible on the wii u menu I think you can press L + R + minus to open the plugin menu, there should be an option called "homebrews on wii u menu" or something similar
