This is a .SAVE file for Pokemon DIAMOND or PEARL. Includes:lv 100 ARCEUSFleeing DARKRAI + SHAYMINMAX SCOREI hope to make some more Pokemon SAVE files HAVE A GOOD TIME!!!!!!!!
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
