Fairly new to Wii modding also. I was having a heck of a time getting Sports Resort to work, even after reading through numerous sites and threads. Finally got it to work tonite via USB drive. I installed WiiFlow channel, installed Cios38rev14. Set error o2 to on in WiiFlow, clicked on game and adjusted setting in there then clicked on play and voila. PM me if you want to know more.
