Just installed the wiikey and tried an original copy of Wii Sports, which worked fine, then tried a backup of Zelda, which would not play. I fixed a connection that looked questionable, tried Zelda again and it worked. Tried it a third time and it did not work again, tried backups of Wii Play and Red Steel multiple times, and those worked fine. Out of about 6 times trying Zelda, it played only on the 2nd and 5th time. Anyone have any thoughts on if it is just the disc or if my connections might be bad. The disc is Verbatim DVD-R burned at 4x, same as the other backups.
