Putting games on to card

Hi
I am new on here and have downloaded some games and when i go to put them on my card it puts them on but they are not showing up on my ds,can anyone help me please

did you extract them using winrar?

I dont no i just downloaded them and saved them to a file on my comp

then you also need to download winrar from www.rarlabs.com and install it. Once it is installed, right-click on the rom and select 'extract here' (with a little book icon next to it) and the .nds file will appear in the folder. That file is the one you copy onto your flashcart.

Ok will do that thanks foe your help .

Yep, you need to put the .nds files on your flashcart.

Or ds.gba, but that's rarely the case ;)
