Thank you all for the quick responses but I have installed rev19 with ios37 and the problem still persists. What do you mean by the force on the iso. It is a NTSC USA Monster Hunter Tri. From what I understand, the wriststrap warning is supposed to come first, then checking wii system memory, then a CAPCOM logo. But my system freezes with a black silent screen in between the 'checking wii system memory" and Capcom logo. What am I not doing?
