well I use an M3 DS simply to play these games on my DS, so if you're interested in purchasing that then search 'M3 DS simply' in google and you'll find sites which sell the item... now the links to DS roms:

h**p://nds-roms.com/?act=home

and

h**p://www.emuwizards.com/index.php

(swap the *'s with tt)

and out of the two above I believe the second link is the best as it updates pretty quick, jap games us and eu versions are available almost immediately as they hit the shops...

Enjoy!

Hi! I'm new here. I recently purchased an NDS Lite. Are there any free nds games I can download?

Or is there a site where I can pay for the downloaded games?

you can visit the above links to download games/roms although you would need an emulator to play them on the pc and I aint sure if there is one which plays all the games.. or you could buy an adapter to play the games on your ds which is pretty cheap in comparison to buying many games. well I hope this helps you.

The nds-roms.com doesn't work..

it did at the time I posted it, sorry mate..

NDS Roms site has been unstable for a while. I think they are changing hosting sites.

another good site is

http://www.g-masters.com/
(downsize, you have a download limit of 2 every 24 hours)

http://frozen-roms.net/index.php?lang=en
(Downsize, older games have broken links)

There isn't a working emulator for the PC.
Try the r4ds or m3 ect.
