postloader on my SysNand wii its EmuNand?The *.dol patch is "dol video patch" setting, you set it to "region patch" so it will convert all "PAL" to "NTSC" because you specified "force NTSC (USA)" in the video mode.
try like that.
if it doesn't work, and other games are working on your usbkey, then you'll have to try using sneek. but it's complicated!
