It could just be a reject micro sd card... Do you have another? I just get mine locally from electronics shops or from a phone shop.
I've had to chuck out two micro sd cards that didn't error but didn't really work (that I bought from Overseas).
When I first started setting up cards for my sons I watched a heap of youtube videos on DSTT cards... Most are old and sites and firmware not current.
Watch this old video
Setting Up and Using TTDS/DSTT Card. There is plenty out there... just browse through them to get an idea of how people set their's up.
Make sure that you have in your TTMENU directory a SKIN directory and under that a DEFAULT directory with files.
I have downloaded some firmware at some stages without this files in it & a friend had trouble with this once too.
Retrogamefan's DSTT Unofficial Firmware 1.17a12 files are excellent. They have everything in them.
Once familiar with the directories and files I set up directories under SKIN (leaving DEFAULT there) ... if you like the default grey you can alway copy default and rename it GREY_DEFAULT and then download & unzip files from
DSTT Themes as there is a
SkinSelectorTT.nds that enables you to change skins.. which kids love.
So I put the SkinSelectorTT.nds in the GAMES directory and the kids can preview the skins by their directories and press A to select them.
Another thing to think about is the space that you have on the card. Don't load the card with games and have no room for the .sav files (Game Saves). It used to be 512k for every game.. but a few games have bigger .sav files now and can be twice as big. If cheats is turned on they take up 5kb too
Hope this helps.
