The SD cards that I have are both 1 gb. They are both for Wii. They both worked up until 2 days ago! It's very odd what's going on. I don't know if its' the computer or the Wii. I did buy a new SD card and I did extract from the Wii and the same exact thing happened! The town is not the same on the computer & the Wii. But gecko is working. Thanks so much for helping!!
