I was one of the first Wii owners in the Uk, getting mine on launch date. December 8th 2007
I recently went to a friends house who has just got his and he has the channel which allows you to transfer to SD. (I can't quite remember what it's called)
Mine does not.
So I phone Nintendo, who said any game from Mario Strikers onwards (whether it be an online game or not) will have on it an update for the Wii for this channel.
I also asked this scenario:
I have Godfather, transfer my data to an SD card and take it to my mates who also has Godfather saved on his internal memory. Once you load the game, which memory does the Wii read?
Answer: The internal memory. So if your mate has it. He has to transfer it off his Wii so you can transfer yours on. :
I also quizzed on downloading save files via the internet (including American) and using them on Uk wii's. He said there should eb no problem but don't use japanese ones as the PAL do not have the characters for the games.
I have no intention of putting my Wii on the internet so for anyone else who is of the same ilk. This may be useful
Thank you please.
