Download latest kernel software from following website http://www.ndstt.com or http://www.buy4ds.co.uk/page.php?
page=download

Unzip the downloaded file into a temporary directory and copy all
files/directories into your memory card. Now in memory card root
directory, there should be the file TTMENU.DAT and the directory
TTMENU. Note the file TTMENU.SYS is created by DSTT when it boots
up for the first time. Then you will have to create a folder called games in
the root directory of the memory card. This will be where all the games are
held by dragging and dropping after they have been unzipped. Only files
downloaded ending with the extension .nds will work.
If you require a DSTT adapter and either a 1gb or 2gb memory card loaded
with the software please e-mail dstt@jollyroger.org.uk for prices etc.
