GHWT Wii: The device inserted in the SD Card Slot cannot be used

[OsakaAzumanga]

I keep getting this error when I installed dlc with wad2bin for ghwt on Wii. I've installed the IOS needed because I have the game on disc but it still comes up. Help?

WT only supports 2gb cards

Better use these days Rb3 deluxe and import the custom songs from WT

If you find a 4GB card that ISN'T SDHC (they're rare) it will also work.
HC (and XC, it's actually the same) uses different commands to the original SD format.
