I have a normal wii that I homebrewed with Mastermod. I have added Wii games Gamecube games, Snes Genesis and Nes games. When I go to wiiflow I have covers for Wii games and Gamecube games because I let the system download them but for SNES, Nes, and Genesis I cant get any of them to add the covers I added manually. I cant tell what Im doing wrong. I matched the names of the games with the png files and have the png files with the exact same names. I tried changing the extension of the png files to smc and tried putting them in different locations but no matter what i do i just see ?s instead of covers.
