Hacking Supercard Rumble Error

[ljosastaur]

Hi

When I turn on my DS with SuperCard Rumble and SuperKey inserted I always get the error "not find the sd please turn off gba".
What can I do to fix this ? I tried searching but I couldn't find any solution to this error.

Thanks

Uhm...insert the SD?

If it is already inserted try reformatting your SD card.
