Nugasa can also dump saves, and doesn´t hang after using it.
I have a simulair USB gecko adapter called "Wiikey SD adapter" from ebay.
The wii doesn´t seem to recognise my FAT formated SD card in the "Wiikey SD adapter".
I use the same SD card for my Wii homebrew.
Do I need some homebrew application to run this "Wiikey SD adapter"?
