ds wont read dstt card

My sis bought a dt card for her dd and last night i tried to load it for her and it wont recognise it at all, tried the micro card in another tt card and thats fine, dodgy card do you think or am i missing something??

Maybe. So nothing happens when you have the DSTT in the DS, it just loads the DS firmware when it shouldn't? Try blowing on the MicroSD, DSTT, and NDS loader.

DS asks to load a card even though it is in!!

So tried blowing etc? Taking out the MicroSD and putting back in and retrying? Where did she get the DSTT?

Yes tried that, she got it from stuffaccess.co.uk, i have had a good look at it today opened it etc and it is nowhere near like my others, it has only the black circle on the chip and the black square is on the otherside and shows through on the ttds sticker on the front of the card, i have ordered her one from where i get them and touch wood had no problemsthanks for your help
