I'm trying to transfer files from my computer to my little brother's Wii, but I don't have an external or internal card reader, is there any way to do it? (Also, not sure if this is in the right section, please move it if it isn't) Note: I've already tried my camera, it doesn't allow me to.
On moons suggestion, if its a microSD, and using a phone, you can use SSHDroid or ESFTP to use your mounted cards as a wireless FTP or SSH server.
