Have a look at the beginning of the guide for instructions to install DVDx.
that fixed my FTP
Hello, got this working ok, great simple guide.
1 question: can it access WBFS partition so I can transfer games from PC to Wii HDD through wireless network?
Sorry but no. It wouldn't be very practical anyway as it would be extremely slow.
I'm not sure what type of router you have but it sounds as if you have the option to set different subnets for the LAN connections and the WiFi (kinda talking out my butt here, lol) or your Wii is on a different connection then what your PC is (more likely I think). The only thing I can suggest is to see if you can configure the router so that the DHCP severs give out IP's on the same subnet if the two do share the same router.
Is there a way that I can see the HDD connected to my Wii if it is in WBFS format?
I can transfer successfully files to my SD card but the ftpii cannot initialize the HDD.
