Yep, that's what I thought too, thanks for your reply. I've tried putting priiloader on the same SD-card I was using. I just copied the priiloader directory (from MMM-36-cIOS_BB2.zip into the apps directory. It shows up nicely in the 'APP manager' (or so) menu of MMM, but when I choose it, it briefly flashes " Loading app..." at the bottom of the screen, then the screen goes black and my only option is pressing the Power button for a few seconds to shut the Wii down.
Is this priiloader version incompatible with this MMM version or so? Or should I just format the SD-card again and use the whole of the MMM-36-cIOS_BB2.zip file?
