We are running wiiflow usb loader with wii SW 4.1U , also have a plug and play fusion modchip on it , everthing was working good for a long time but now some games are not booting , only thing i can think of we changed is that we added acouple sims games to the HDD that don't work well , other than that i have no clue what would have happened to these games that were working fine , wii music and wii sports are 2 of the ones not working . Anyone know what i should try ?

thanks
