got the location of 'hard to find' nds roms?

Hi guys anyone know anywhere to find some of those really hard to find games no longer available from this site or not available at all.
The Sim two nds can be found after googling 'trashman sims 2' and following a link to a torrent site called 'general search'
I am trying to find bindi irwin presents Big ocean adventure for my kids, but still no luck after 6 months. It has been out over a year in Australia.
Anyone else with useful tips for ANY search for roms is appreciated ;)
Thanks guys!

If you want torrents go to : www.mininova.org or www.thepiratebay.orgIf you can't find it there go to the Rom Request section of the forum and request for it over there.:)
