The plugin dol file must be in the wiiflow/plugins folder. and don't name it boot dol - Name it 'fceugx-mod9.dol' and make sure you have this line in the corresponding plugin ini file - 'dolFile=fceugx-mod9.dol' And no you are not supposed to rename and move any of the dol files to apps. That only applies to the actual hombrew emu apps. These are modified to be plugins for WiiFlow. Also after you rename it and put it back in wiiflow/plugins. when you run wiiflow you may have to go to the home menu and select rebuild cache.
