ttds no games in menu?

Hi, Trying to get the games i have downloaded to run but having probs, downloaded latest driver from website and tt menu comes up on my ds but no games are listed, just sys options in top left corner, I know ive done something wrong, but what? help please, dont know if this helps but games are saved as .rar? i also formatted my sd card (fat) b4 loading anything on to it.

Yeah, the proper extension for ds games is .nds, if it's in .rar format, you'll need to extract it. Go here for a tutorial. https://www.romulation.org/forum/index.php/topic,3880.0.html
