Hi bought my Wii couple of years ago because wife wanted to outdo sister got it chipped with wii2 key i think!) worked fine but wife never looked at it kids prefer xbox 360.
we have only played... a couple times in last 2 yrs but now if i try to play new backups they dont work!!
the original back ups still work.
i cannot find thread to help as i dont know what problem is
If you have wiikey2, you should update it. Register here Wiikey Resources & Downloads and download the latest patch (1.3 "Odyssey") from the members area and burn it to a DVD, this fixed my problem and that update runs SSBB and NSMB too.
