have a super monkey ball 2 for GCN. wanted to play it again after finding it 5 years later and it wouldnt load up on my first GCN. so tried it on my second backup GCN and it didnt read on that one either. put in mario golf toadstool tour just to make sure the gamecube's were reading disks, and it loaded up just fine. the weird thing is, 5 years ago i remember playing this game and it worked perfect. nothing has changed with the disk in that time, just hasnt been used. looked at the back of it and no scratches. is there a suspect area on these games where to look if it stops working?
