My NDSTT is not being recognised by my DS Lite

Hi all,

Am desperately trying to get my NDSTT to work, have downloaded the files from www.ndstt.com but when I put it in my DS Lite it says there is no DS Card inserted.

My DS came free with a mobile phone and the box says it's for sell in Singapore, Taiwan and Thailand only, would thids have any affect on it? English games do work in it.

Thanks all.

 

Does it say, or does it just continue with the Nintendo GUI? As DSTT, when inserted, takes over the GUI of Nintendo, so when it says the health warning screen etc. it skips directly to the DSTT.
