Try this
http://www.gamefaqs.com/portable/ds/save/925601.html. The only thing you need to do is convert them try the save converter on the disk that came with the R4.
I tried to do that but when i do download a file from that site and try to edit it on Pokesav before putting it on my R4DS it is all blank.
and i cant put the save on my R4DS 'coz when i do the game just starts a new game save.
BTW: That converter SUCKS this one is better:
