Henry Hatsworth!

Whenever I try and start up the game on supercard DS ONE its comes up with "the data could not be written . Please turn the power off and reinsert the game card''. It says this with every version I download. any help please?

anyone?

Get the latest firmware and check if you have extracted and downloaded it right

If you're using an R4 then you'll need to do an arm7 patch. Just search the forums to find out how.
