where can i download games for the ds online?

I download my DS roms for my R4 here:

http://www.dashroms.com/

Part of the above site is closed for maintenance so you can only get certain roms. Maybe this next one that I also used would be better, although you cannot search so you just have to keep going down the list:

It's a shame the nds-roms.com has closed down, I used to use it too!

YOu can go to ndsuniverse and download a lot of good nds game roms

Personally I use:

http://www.mininova.org/

And then I use Razilla to de-crypt it so it is the correct file.

If you want to challenge me in a certain game which I might have feel free to contact me :)

if you have a wii with wi fi go to the wii channel and download free games for your ds
